Helps ingest data, enhances business resilience and problem-solving capabilities
Pros and Cons
  • "The two features I appreciate most in Splunk Enterprise Security are the content management system and the inter-incident review dashboard."
  • "They could offer pre-built search queries for everyday use cases like brute force attacks, DDoS attacks, and other security threats."

What is our primary use case?

I have created various correlation searches to develop use cases for detecting security threats. For example, I have created use cases to identify brute force attacks, unauthorized access, denial of service attacks, and distributed denial of service attacks. To date, I have developed a total of 190 use cases for our environment using Splunk Enterprise Security.

How has it helped my organization?

The end-to-end visibility provided by Splunk Enterprise Security is crucial. Its user-friendly interface makes it easy to navigate and configure. The intuitive options allow for simple customization, enabling users to easily select and configure settings. This feature, combined with the excellent support from the Splunk team, makes it a valuable tool for addressing enterprise security issues and creating or modifying use cases.

Splunk's website provides a variety of simple commands for identifying security events. These commands and pre-built security fields make it easy to detect real-time attacks, monitor environments, and identify security threats. Splunk offers a more straightforward and efficient approach than other monitoring tools.

Splunk automatically ingests and normalizes data, eliminating the need for human intervention. When data is ingested, it is automatically converted into index-friendly formats within most source pipes.

The MITRE ATT&CK framework is a valuable tool for security teams, and its integration with Splunk Enterprise Security offers significant benefits. By mapping specific MITRE ATT&CK tactics to Splunk use cases, analysts can quickly identify the root cause of security incidents and access relevant information for remediation. For example, if a brute force attack occurs, an analyst reviewing the incident can quickly determine the corresponding MITRE ATT&CK tactic and access detailed information about the attack, including potential solutions, mitigation strategies, and potential future actions. This seamless integration between MITRE ATT&CK and Splunk empowers security teams to respond to threats more effectively and efficiently.

Splunk has significantly enhanced my business resilience and problem-solving capabilities. Due to the urgency of different issues, there are four types of Splunk support cases: P1, P2, P3, and P4. P1 cases are incredibly critical and require immediate attention. If a business-critical issue arises, I can open a P1 case, and the Splunk support team will respond within 15 minutes. This rapid response has enabled me to resolve critical issues promptly. For P2 cases, the support team typically connects within two to three hours. P3 cases receive a response within 24 hours. Overall, the Splunk support team consistently resolves issues efficiently.

After deploying the use case, we immediately observed the benefits of Splunk Enterprise Security. We can instantly monitor enterprise security use cases in our environment without delay. However, as a precautionary measure, we deploy use cases and monitor them for seven days. If the use case does not generate excessive noise within this period, we deploy it to the final environment. Otherwise, we refrain from deployment. Splunk's capability allows us to deploy use cases within seconds.

Splunk helps me consolidate all the data, such as networking and cyber security data. If there are other types, such as behaviour analysis, we can perform them with the help of Splunk. But I'm mainly in the cyber security field, so I am more concerned with Splunk for cyber security data only. For example, in my PhD, I created my thesis based on medical performance monitoring. I monitor the performance health condition of one million people with the help of Splunk. So, this is not a cybersecurity use case I'm creating there. I monitor the health condition with the help of a Splunk Enterprise. If a health condition is significant, the alert immediately goes to the doctor, physician, and their relative.

My alert volume has decreased significantly. Splunk is a machine that generates alerts based on specific use cases or service queries. Before implementing a new use case or alert, we must analyze how many alerts it will trigger. If it generates fewer than one alert per day, it's acceptable. However, I will only deploy it if it generates one daily alert. This approach allows me to reduce the alert volume effectively using Splunk Enterprise Security.

Splunk streamlined my security investigations by consolidating logs into a single repository. The Splunk community provided invaluable assistance, enabling me to quickly find answers to my security-related questions and address concerns promptly. By leveraging the collective knowledge of the global community, I expedited my security processes and enhanced overall security measures.

Splunk reduces the mean time to resolve because it enables L1 SOC analysts to view relevant data in the power role field directly. For example, when a brute force attack alert triggers, analysts can easily see the source IP, time of the alert, user, destination IP, and other critical fields. This immediate access to information allows for swift preventive measures, countermeasures, and efficient resolution of cybersecurity issues. Splunk's clear and intuitive interface empowers even junior analysts with only one year of experience to effectively apply their knowledge and address security challenges.

What is most valuable?

The two features I like most in Splunk Enterprise Security are the content management system and the inter-incident review dashboard. The incident review dashboard allows us to directly view significant events triggered by the use cases I've configured within the content management system.

What needs improvement?

I suggest that Splunk provide the same resources on its platform, as on other websites through Google. For instance, they could offer pre-built search queries for everyday use cases like brute force attacks, DDoS attacks, and other security threats. These queries would be generated based on my specific data, saving me the time and effort of creating them manually. This would be incredibly beneficial and align with the AI capabilities already present in Splunk Enterprise Security.

Learn what your peers think about Splunk Enterprise Security. Get advice and tips from experienced pros sharing their opinions. Updated: March 2025.
842,296 professionals have used our research since 2012.

For how long have I used the solution?

I have been using Splunk Enterprise Security for eight years.

What do I think about the stability of the solution?

In the eight years I have used Splunk Enterprise Security, I have experienced no stability issues. There has been no downtime or crashing. The only problems I have encountered were temporary interruptions in some features, lasting approximately 15 minutes.

What do I think about the scalability of the solution?

Splunk Enterprise Security is highly scalable. For example, I currently have one terabyte of data to deploy, and tomorrow, I need to deploy ten terabytes. In that case, the system can easily accommodate the increased load without compromising performance. It is extremely fast and efficient, ensuring no issues even as the input data volume grows. The system adjusts quickly to meet the demands of expanding data requirements.

How are customer service and support?

I have contacted Splunk technical support three times in the past fifteen days due to various issues encountered while using Splunk. Each time I reached out, they responded promptly and assisted me in resolving the problems.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I have used several alternatives to Splunk, such as AppDynamics, Dynatrace, and Oracle Enterprise Manager. However, I have found Splunk Enterprise and Splunk Enterprise Security the most effective tools for my needs. These platforms are easy to use, allowing for flexible parameter customization and dynamic adjustments to meet specific requirements.

How was the initial setup?

The initial deployment of Splunk Enterprise Security was straightforward due to my prior experience learning and using various tools. I found it to be significantly easier to implement than similar software.

I set up my lab independently, being new to the environment at the time and eager to learn. I visited the Splunk website and discovered the free courses they offer. Using these courses, I successfully configured my lab. Splunk provides valuable assistance for setting up personal labs and offers a 60-day trial version. This version allows for direct log setup and hands-on practice of Splunk skills without cost.

What's my experience with pricing, setup cost, and licensing?

Splunk Enterprise Security's pricing is competitive. For instance, the cost typically increases proportionally with the daily license volume. For example, purchasing a 100 GB license per day is less expensive than buying one GB per day. A discount is offered for larger volume purchases.

What other advice do I have?

I would rate Splunk Enterprise Security eight out of ten.

Which deployment model are you using for this solution?

We can manage all the logs from every device on a single dashboard
Pros and Cons
  • "Splunk can deliver more information by going deeper. By creating a dashboard, we can identify the root cause of the threat. Let's say I have a firewall from Check Point. Splunk will find the dashboard for Check Point, implement it in our environment, and connect it to the Check Point firewall logs, which are shown on the dashboard. If we request a custom dashboard, the engineer will take longer to complete the task."
  • "Splunk should align its security principles with those of other vendors like SentinelOne. Splunk has mature APIs that can communicate with various security applications and devices. Splunk can process more to produce an understandable dashboard."

What is our primary use case?

I work in the pharma industry, and I use Splunk to aggregate all my reporting logs for my firewall and Active Directory logs. We have anti-spam, web application firewalls, and other solutions to secure our perimeter. We use Splunk for log management and have a stack to transpose a log from the firewall to a VM. When we directly feed the firewall logs to Splunk, they become intermittent and freeze. 

How has it helped my organization?

The biggest benefit is that we can manage all the logs from every device on a single dashboard. I can put the log from the core system into Splunk to analyze for abnormal behavior and show that to the developer to improve it. Splunk can also analyze our security devices for security posture for CRM and ISO requirements, helping the organization obtain its ISO certificates.

We started to see the benefits of Splunk when we created our first dashboard. Based on the dashboard information, we can get deep insights from the log, where we define a security incident or event and assign a score to repetitive events. For example, we receive brute force attacks, where the hacker attempts to try a thousand or a million passwords. This will trigger alerts on the dashboard or email. We are not monitoring 24/7, so we can get alerts from Splunk. We can detect threats faster from firewalls and antivirus. 

The consolidation helps us identify the source of the threat faster. They can analyze the forensics to dig into information from the log and correlate the devices. A unified log from various devices can simplify the IT team's response and reduce the alert volume by 35 percent. 

What is most valuable?

Splunk can deliver more information by going deeper. By creating a dashboard, we can identify the root cause of the threat. Let's say I have a firewall from Check Point. Splunk will find the dashboard for Check Point, implement it in our environment, and connect it to the Check Point firewall logs, which are shown on the dashboard. If we request a custom dashboard, the engineer will take longer to complete the task. 

I can create a custom dashboard for the firewall, antivirus, or endpoint protection. This will take time to complete because they need to understand the log type and mitigation of the process from the system or API.

Splunk helps us manage our hybrid environment, including our email system. The main email system is Microsoft Exchange, which is deployed on-premise, and the second is Office 365. There isn't much security for the hybrid environment. We get logs from the web application firewall, the firewall, and the anti-spam solution. 

What needs improvement?

Splunk should align its security principles with those of other vendors like SentinelOne. Splunk has mature APIs that can communicate with various security applications and devices. Splunk can process more to produce an understandable dashboard.

Splunk's latest version is much better than before. It's more resilient and powered by AI. It can ingest more complex logs. It will be better because we're using the legacy one.

For how long have I used the solution?

I have used Splunk for around six years.

What do I think about the stability of the solution?

I rate Splunk 10 out of 10 for stability. We've had no problems as long as we ensure we have capacity planning for the log system, which is growing every second. 

What do I think about the scalability of the solution?

I rate Splunk nine out of 10 for scalability. 

How are customer service and support?

I rate Splunk support eight out of 10. Support was great, and they responded quickly. 

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

Splunk is our first SIEM, but we'd like to explore Wazuh more.

How was the initial setup?

It's hard to say whether deploying Splunk was straightforward or complex because sometimes the consultant did the work for us. I handled the operations side, and the consultant did the project itself. It was completed in two days. 

What's my experience with pricing, setup cost, and licensing?

Splunk is expensive. It's based on the data inside the log. If you produce bigger logs, the cost goes up. We pay a license up to a set size, let's say 100 gigabytes, and if we have 101, they charge us for the overage. We pay about a billion Indonesian rupiah. 

There are many cheaper solutions. Microsoft Sentinel is also a little expensive, but there are cheaper ones like Wazuh, Graylog, and Rapid7.

What other advice do I have?

I rate Splunk Enterprise Security nine out of 10. If you want to use Splunk, you can try the free version, which goes up to half a gig. You can feed a log from the Active Directory. If you take that information directly from Active Directory, it will be hard to read. Splunk provides a good dashboard. 

Splunk is an excellent choice for an organization that needs a fully scalable and highly customizable solution. We can customize the dashboard to combine all the device logs. Unfortunately, others still need to learn how to do that. It depends on an organization's needs and resources because it's not cheap.

It's on the higher end of pricing, which can be a significant factor for small organizations with budget constraints. It's more appropriate for the enterprise level and companies with over 500 employees.

User-friendly, feature-rich, and best support
Pros and Cons
  • "It is user-friendly. It is more effective than other solutions. The support and help for troubleshooting and the documentation from Splunk make it very effective."
  • "The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost."

What is our primary use case?

There are many use cases. Most of the use cases are related to security, data integration, and data sources. 

How has it helped my organization?

Splunk Enterprise Security helps with real-time detection. When we integrate any data source, if any external IPs or external devices are accessing that data source, we get notified. We get alerts based on the use cases we develop.

Splunk Enterprise Security has improved the incident response time a lot. Splunk is doing log ingestion, and it is also used to search the database for issues. It is ingesting and identifying. All that is happening in a single solution.

Splunk Enterprise Security is very easy to use. We can monitor anything. We can monitor and integrate any type of applications and servers. It is very easy and effective. I work with different security tools, but none of the security tools has these many features.

Splunk's documentation is clear. Irrespective of the environment we are working in, we have clear documentation.

One of our clients is using the Threat Intelligence Management feature. The actionable intelligence provided by the Threat Intelligence Management feature is very good.

I have been working with different vendors. Splunk Enterprise Security is a very effective and user-friendly tool. Whether it is Sentinel, LogRhythm, or QRadar, each one of them has its own limitations, but Splunk has all the features.

Its benefits can be realized very quickly. It does not take lots of days or months.

Splunk Enterprise Security has helped to reduce our alert volume. There is a 60% to 70% reduction.

Splunk Enterprise Security has helped speed up our security investigations.

What is most valuable?

It is user-friendly. It is more effective than other solutions. The support and help for troubleshooting and the documentation from Splunk make it very effective.

It has multiple features. It has data integration, search, reporting, and alerting.

It does not need any advanced programming. It only requires basic programming.

What needs improvement?

In terms of features, it does not need any improvement. Everything is good so far. The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost.

For how long have I used the solution?

I have been working with Splunk for more than 7 years. I have worked with Splunk Enterprise, Splunk Enterprise Security, Splunk Cloud, and on-prem Splunk.

What do I think about the stability of the solution?

It is very stable. We never had any issues or bugs.

What do I think about the scalability of the solution?

Its scalability is good.

How are customer service and support?

The support from the Splunk side is very good. They provide the best support.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I have used Sentinel and QRadar. I switched because of the advanced features, support, and good documentation. It is very effective. It is the best solution. The only problem is the cost.

How was the initial setup?

I have worked with cloud deployments and on-prem deployments. Its initial setup depends on the environment. It is sometimes complex, and sometimes, it is very easy. We also get good support from them.

Our implementation strategy has 3 phases. We first go for development, and then we go for Pre-Prod. After that, we move to Prod.

What about the implementation team?

Currently, I am the only one handling the deployment, but when it comes to operations, we need at least two to three people.

It requires maintenance. Generally, 2 people are required, but for my clients, I am the only one who is taking care of the maintenance.

What was our ROI?

We have seen an ROI.

What's my experience with pricing, setup cost, and licensing?

It is expensive. I work for multiple clients. I am working for more than 5 clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel.

What other advice do I have?

I would recommend Splunk Enterprise Security to anyone who is looking for a similar solution. This is the only solution with all these features.

I would rate Splunk Enterprise Security a 9 out of 10. It is stable, user-friendly, and feature-rich. It is very helpful. Even though it is expensive, the stability, support, and technical documentation make it very effective.

It's easier to customize than other solutions
Pros and Cons
  • "We have created a few custom use cases for Splunk that have helped us detect threats faster. For example, we set up endpoint-related data models and specialized setups for various scenarios. It's more efficient than some other products I've used."
  • "The access and identity features could be improved. For example, let's say we have onboarded 65 logs. Now, we can identify the various processes, but we run into trouble when we're updating the processes for AWS CloudTrail, EDR, MDR, and XDR."

What is our primary use case?

I am on the intelligent engineering team responsible for onboarding logs and operationalizing Splunk Enterprise. We have a separate team for creating use cases and other stuff. I onboard logs and manage the infrastructure. When you onboard various logs, it creates different data models and normalizes the fields for compliance.

How has it helped my organization?

We have created a few custom use cases for Splunk that have helped us detect threats faster. For example, we set up endpoint-related data models and specialized setups for various scenarios. It's more efficient than some other products I've used. 

Splunk has sped up our security investigations. We can automate some functions using playbooks, like automating scans for perimeter vulnerability. If you have the signatures, Splunk can intervene automatically to block threats according to the playbook. 

What is most valuable?

Splunk lets us integrate multiple third-party threat intelligence feeds. We can also customize the data models for correlation more than we could with competing SIEM solutions. We can filter out the noise and see our alerts. 

I created some security reports or dashboards. We also have dashboards for user requests related to our firewalls, like Palo Alto and traffic or activity alerts. We can also see where we're getting a lot of authentication failures, etc. We've also created some other custom use cases, like using VPN logs and use cases for analyzing the national origins of repetitive malware. We have integrated some other solutions like Carbon Black EDR or MDR as well as Vectra, which is fully automated with AI. They have their own signatures.

We get decent visibility with Splunk and integration with data visualization tools like Grafana. We also have various threat intelligence feeds that are updated regularly with the latest IOCs and signatures, which we can use for threat hunting. 

What needs improvement?

The access and identity features could be improved. For example, let's say we have onboarded 65 logs. Now, we can identify the various processes, but we run into trouble when we're updating the processes for AWS CloudTrail, EDR, MDR, and XDR. 

For how long have I used the solution?

I have used Splunk for the past three or four years. 

What do I think about the stability of the solution?

Splunk is stable. It has around 97 percent uptime in my environment. 

What do I think about the scalability of the solution?

I rate Splunk Enterprise Security nine out of 10 for scalability. 

How are customer service and support?

I rate Splunk technical support seven out of 10. We rarely rely on Splunk support except for critical upgrades and migrations. Sometimes, we open a ticket if we see a performance problem, and they find a solution. Typically, we find a solution for our issues online in user forums or knowledge bases.  

How would you rate customer service and support?

Neutral

Which solution did I use previously and why did I switch?

Previously, we used some open-source solutions, Sumo Logic, and Graylog. 

How was the initial setup?

We have Splunk deployed in two environments for different purposes. One is for ITSI, general dashboards, and our APM application. That is deployed in the cloud. We have it in an on-premises environment for enterprise security. We have a cluster that spans three data centers. Deploying Splunk is easy if you have some experience.  Configuring the log sources, managing the indexes, and learning all the features is more challenging. 

Splunk doesn't require maintenance aside from the disaster recovery and DLP aspects. We have a huge environment in different data centers set up for high availability. 

What was our ROI?

Splunk is expensive, but you can get a lot out of it if you have the expertise and know how to customize it. It's more customizable than other platforms.  In Java or .NET, everything is pretty defined, so you can't do much customization, whereas Splunk lets you customize dashboards, alerts, and reports using SQL. The cheapest solution is always open source, but these products don't have many capabilities. They might work in a small environment. I would recommend trying LogRhythm, ELK, or Google Chronicle.

What's my experience with pricing, setup cost, and licensing?

Splunk is very expensive because we have recently integrated another solution, and 40 percent of the licensing cost is driven by that. 

What other advice do I have?

I rate Splunk Enterprise Security nine out of 10. I would recommend Splunk to others. When implementing Splunk, it's crucial to set up your use cases, onboard threat intelligence and log sources, and create data models. Using simple XML language, you can create a data model and a simple pivot table to generate complex reports.

Offers good visibility into multiple environments, significantly reduces our alert volume, and speeds up our security investigations
Pros and Cons
  • "We can automatically suspend or terminate suspicious sessions."
  • "There are limitations with Splunk not detecting all user activity, especially on mainframes and network devices."

What is our primary use case?

Through Splunk Enterprise Security, we have implemented extensive login integration. This allows us to monitor and restrict access for sensitive accounts, such as superuser and master accounts when password rotations occur. If a login attempt is made for such an account, Splunk triggers a real-time workflow that automatically generates a P1 ticket for the Help Desk and IAM Operations teams to investigate and take necessary action.

Beyond real-time monitoring, we have established additional security measures. We utilize locks within JBOS to control manual account check-ins and user server activity, such as password verifications. Splunk ingests logs from any configured PAM solutions, enabling auditors and our technical team to readily access and analyze all privileged activities. We can also generate reports for session management, session logs, and audit logs.

How has it helped my organization?

Splunk Enterprise Security can enhance our organization's detection capabilities. While SIEM solutions are essential for most companies, choosing the right one is crucial. Splunk Enterprise Security is a popular option, and its benefits extend beyond technical teams. It can empower audit teams and provide visibility into user activities, including data sharing and out-of-the-box reports. Splunk's strength lies in its flexibility. It can integrate with other tools to fill any gaps in its capabilities. However, relying solely on one tool like Splunk isn't ideal. PAM tools often have built-in auditing and reporting features, but they may not offer the same level of customization or enterprise-wide visibility. This is where Splunk comes in. It provides a complementary solution, offering multiple ways to generate reports and gain insights.

We recently focused on enhancing Splunk Enterprise Security's identity correlation capabilities. This involved integrating it with several chosen applications. One key integration involved moving from Puppet to Ansible for managing privileged access management and performing virtualization tasks. Ansible allows for agentless management, meaning we don't need to install agents on every server. For broader asset management, we leverage CI/CD tools for efficient deployment across all servers. These tools significantly reduce the manual effort required.

Splunk Enterprise Security offers good visibility into multiple environments. However, certain applications in the financial sector, particularly for high-risk activities, still face regulatory or compliance restrictions that prevent them from migrating to the cloud. Despite these limitations, we see forward-thinking institutions like JPMorgan Chase taking the initiative to move lower-risk applications to the cloud. This trend extends beyond finance, with other sectors like healthcare already embracing cloud adoption.

In my assessment, Splunk Enterprise Security earns an eight out of ten for its ability to detect malicious activities and breaches, but only a seven out of ten for taking action.

Once we have an enterprise version set up, Splunk handles the initial identification steps of potential threats, saving us manual effort. I'd even rate Splunk a perfect ten for this initial phase. However, subsequent action items still require manual intervention – a bottleneck we can minimize with additional tools like endpoint security threat analytics that integrate with Splunk. This would enable complete threat modeling, including asset identification and mitigation directly within Splunk. Unfortunately, our company hasn't invested heavily in threat modeling, with a limited team compared to the larger IAM and risk groups. Thankfully, the industry is recognizing the importance of threat modeling, leading to increased hiring in this area.

Splunk Enterprise Security has significantly reduced our alert volume. This has freed up a substantial portion of the IM operations team, who were previously tasked with continuously monitoring for threats and anomalies across various applications, not just spam. By leveraging these threat detection tools, we anticipate being able to reduce IM operations staff by at least 50 percent.

Splunk Enterprise Security facilitates the acceleration of our security investigations, reducing the required time from one week to one day.

What is most valuable?

One of the features I appreciate most is privileged account threat detection. It identifies suspicious activity associated with fraudulent accounts detected on the endpoints of target systems.

Furthermore, the platform offers threat analysis and reporting that leverages Splunk data. This allows for the detection of irregular user access from machines directly. This functionality is crucial in large PAM environments with thousands of users, as it identifies inactive accounts.

For scenarios where users might not access the PAM portal to change passwords, different policies are implemented. Splunk plays a key role in detecting irregular user activity. By establishing a three-month threshold, we can identify cases where users haven't used their accounts despite not being on leave or vacation. Such instances warrant investigation to determine the continued need for privileged access.

We can automatically suspend or terminate suspicious sessions. We have also customized reporting within Splunk.

What needs improvement?

There are limitations with Splunk not detecting all user activity, especially on mainframes and network devices. This is because Splunk relies on agents, which cannot access certain workstations. In these cases, we have to rely on application data. For example, with mainframes, manual reports are generated and sent to Splunk, limiting visibility to what's manually reported. This lack of automation for specific platforms needs improvement from Splunk. Additionally, API access is limited for other applications that rely on API calls and requests. This requires heavy customization on Splunk's end. These are the main challenges we've encountered.

Monitoring multiple cloud platforms, like Azure, GCP, and AWS, with Splunk Enterprise Security presents some challenges. While Splunk provides different connectors for each provider, consolidating data from two domains across distinct cloud environments can be complex. However, leveraging pre-built templates and Splunk's data collation capabilities can help overcome these hurdles. Despite initial difficulties, I believe Splunk can effectively address this task, earning it an eight out of ten rating for its multi-cloud monitoring capabilities.

While Splunk Enterprise Security offers insider threat detection capabilities, its effectiveness could be enhanced by integrating with additional tools, such as endpoint security solutions. This integrated approach is particularly crucial for financial institutions, which often require dedicated endpoint security teams. While using multiple tools is valuable, further improvements within Splunk itself are also necessary. Considering both external integration and internal development, I would rate its current insider threat detection capabilities as three out of ten.

Threat detection is where Splunk falls behind. While it offers tools, other use cases require additional work. PAM is an enterprise tool that centralizes information about users, servers, and everything else. It needs real-time monitoring, which I haven't seen in any of the companies I've worked for. They only rely on Splunk for alerting, but real-time monitoring should be handled by the endpoint security team's tools. This means there's no detection or analysis at the machine or endpoint level. Additionally, threat analysis reporting is also absent.

For how long have I used the solution?

I currently use Splunk Enterprise Security.

What do I think about the scalability of the solution?

Splunk Enterprise Security's scalability and ability to handle large data volumes is great. Splunk can manage a lot of users and applications. I would rate the scalability a nine out of ten.

How are customer service and support?

The technical support is a bit expensive but they respond quickly.

How would you rate customer service and support?

Positive

What's my experience with pricing, setup cost, and licensing?

Splunk Enterprise Security is expensive but the solution is equipped with a lot of features.

What other advice do I have?

My rating for Splunk Enterprise Security depends on the type of logs being analyzed and the company's specific environment and setup. If a company is actively comparing Splunk to competitors and their environment aligns well with Splunk's strengths, then a score of nine out of ten is justified.

Pros and Cons
  • "Splunk Enterprise Security is a standard solution providing good customer service and partnership."
  • "Splunk should have more regional data centers in the Middle East."

What is our primary use case?

We mostly use the solution for compliance, logging, log storage, and root cause analysis. In 2015, we had AIG as a client, and they only had Splunk. Splunk Enterprise Security is one of the oldest solutions that did the logging and storage.

How has it helped my organization?

Splunk has fantastic brand value, which helps us sell it as resellers. The solution's pricing is quite competitive. The solution meets all the requirements. As a compliance person, I know that log storage is very important for data privacy compliance guidelines like ISO or CCPA. Splunk provides all of those compliances and checkmarks.

What is most valuable?

I like that the tool is light and the agent doesn't slow down the machine. Splunk Enterprise Security is a standard solution providing good customer service and partnership.

What needs improvement?

The solution should improve regional knowledge of the new regulations coming out of the Middle East. As a consulting firm, we are currently targeting many Middle Eastern markets, including Saudi Arabia and Dubai. They don't have a local server support cloud center there, which is a big issue because they don't want their data to go out of the region. Splunk should have more regional data centers in the Middle East.

For how long have I used the solution?

I have been using Splunk Enterprise Security for five years.

What do I think about the stability of the solution?

Splunk Enterprise Security provides good stability.

What do I think about the scalability of the solution?

The solution's scalability is fantastic. Even 10,000 to 50,000 endpoints don't slow anything down. The servers, log storage, and ingestion work smoothly, irrespective of whether there are 5,000 or 50,000 endpoints.

How are customer service and support?

The solution’s technical support is very good.

What was our ROI?

Our customers using Splunk Enterprise Security don't have any compliance issues, and they don't get fined by the regulators, which saves them money.

What's my experience with pricing, setup cost, and licensing?

Splunk Enterprise Security's pricing is pretty competitive.

What other advice do I have?

I'm a consultant who uses Splunk for other clients. It's important for the clients that it can communicate with all kinds of devices, like firewalls, WAFs, servers, endpoints, switches, and routers. All of that is figured out over time, which is useful.

Splunk Enterprise Security is a good tool for finding security events across multi-cloud, on-premises, or hybrid environments.

Splunk has helped improve our organization's ability to ingest and normalize data. It can also identify and solve P1 or high-critical-priority problems in real-time.

Splunk Enterprise Security has helped us reduce our alert volume by around 50%.

The solution provides us with the relevant context to help guide our investigations, and this context information has impacted our investigation process. Having all the data in a single place does help with post-incident response and forensic root cause analysis.

Splunk Enterprise Security has significantly helped speed up our security investigations. I save 60% to 70% of my time because it's easier to find what I want to find through the tool's user interface.

Splunk Enterprise Security has helped reduce our mean time to resolve by around 50%.

Overall, I rate the solution ten out of ten.

Robust threat detection with extensive customization options and seamless integration with third-party security solutions
Pros and Cons
  • "One key advantage of Splunk over competitors like IBM QRadar is its superior device integration capabilities."
  • "Delays in responses from the technical team can pose challenges for both vendors and clients, especially considering that Splunk applications and machine solutions are critical assets."

What is our primary use case?

We typically suggest Splunk IT builds for customers with significant EPS requirements and large-scale data environments. While other solutions like Foundry and IBM QRadar may be popular, they often have limitations in handling big data effectively.

How has it helped my organization?

It offers visibility across various environments, encompassing diverse infrastructures such as multiple firewalls. Some environments are entirely cloud-based, while others follow a hybrid model with services both on-premises and in the cloud. The infrastructure setup varies depending on the organization's specific model and needs.

We are highly satisfied with the level of visibility provided by Splunk.

It offers advanced threat detection capabilities to assist organizations in uncovering unknown threats and anomalous user behaviors. Splunk is utilized for integrating various devices including firewalls and other security controls, enabling coordination of logs and the creation of use cases. Analysts investigate alerts generated by these use cases, identifying and mitigating potential threats. Additionally, Splunk provides built-in and customizable use cases to enhance security measures.

We utilize the threat intelligence management feature in Splunk, which includes the provision of IOCs. Additionally, we have third-party intelligence services integrated into Splunk, which alert us whenever any related feature is triggered.

The effectiveness of the actionable intelligence offered by the threat intelligence management feature hinges on the third-party engines integrated or enabled within it. While false positives are common and require investigation, there are instances where identified IOCs are indeed malicious. In such cases, actions like reporting or following a predefined playbook can be taken.

We leverage the Splunk Mission Control feature, and I have hands-on experience with it. Typically, I manage it through Splunk, where I create rules, reports, and dashboards. Enabling third-party intelligence and other features involves a thorough review process, particularly when onboarding new clients. Once set up, we regularly review our baseline configuration and make adjustments as needed to ensure optimal performance. The Splunk Mission Control feature aids our organization in centralizing our threat intelligence and ticketing system data management. We integrate third-party intelligence services along with our company's proprietary advisories, particularly in the retail sector. This integration enables us to maintain a comprehensive reference set within Splunk.

We utilize the Threat Topology and Mitre ATT&CK Framework features to enhance our understanding of threats. These features offer micro-mapping visibility, allowing us to align identified needs with specific techniques.

The purpose of the Mitre ATT&CK Framework is to aid in discovering and understanding the full scope of an incident. Using the micro-hypotheses, we assess whether our subcontractors are adequately covered. We evaluate our rules to determine whether we have sufficient use cases for tactics and techniques, such as initial access. This process helps us identify any gaps in coverage within the Mitre ATT&CK Framework and address them accordingly.

Splunk is a valuable service for analyzing malicious activities and detecting breaches. However, I recommend ensuring comprehensive coverage of threats by integrating all relevant devices and maximizing visibility into logs. For instance, leveraging firewall logs enables the detection of anomalies at the network level, while logs from EDR solutions can identify malicious activities on endpoints.

Splunk has significantly improved our threat detection speed. Comparatively, when working with other teams, I've found Splunk to be more efficient due to its big data capabilities, allowing for faster analysis compared to IBM QRadar and similar tools.

The primary benefits our customers experience from utilizing Splunk in their organization are significant. While Splunk may be more costly compared to other machine solutions, its effectiveness shines in handling large volumes of data, making it ideal for organizations with extensive data needs. Unlike solutions like IBM QRadar, which may struggle with processing large amounts of data efficiently, Splunk's big data capabilities enable it to excel in such scenarios.

Splunk Enterprise has effectively decreased our alert volume across various use cases. Whenever we develop a new use case, we carefully analyze it, occasionally encountering false positives. In such instances, we collaborate with IT to whitelist these cases. Over time, as we accumulate a robust whitelist, the ratio of false positives diminishes, resulting in a higher rate of true positive alerts.

It has significantly accelerated our security investigations, proving to be immensely helpful. We can efficiently track and analyze user activities with most devices integrated into the Splunk environment. The visibility provided by Splunk allows us to coordinate activities seamlessly and thoroughly investigate any detected incidents. Whether it's identifying the origin of an activity or uncovering correlations between events, Splunk enables us to piece together the entire user activity chain swiftly and effectively.

Compared to other SIEM products, I've found that Splunk offers quicker alert resolution times. Its ability to efficiently handle large data volumes contributes to this advantage. Analysts typically have predefined playbooks and investigation checklists for when alerts are triggered, which Splunk supports well. Additionally, we've customized dashboards and reports to further streamline our detection process, ultimately reducing our response time.

For those seeking cost-effective solutions, Elastic Stack stands out as a popular choice due to its single-source administration and competitive pricing. Many industries, recognizing its affordability and robust services, are swiftly adopting Elastic and other similar solutions like Wazuh.

The value of resilience in a SIEM solution varies depending on the organization's preferences and requirements. Some organizations prioritize high availability and disaster recovery capabilities, which contribute to resilience.

What is most valuable?

As an analyst, I've observed that Splunk offers a variety of rule sets, along with built-in and customizable use cases. We have the flexibility to create dashboards and expand reports for management visibility. One key advantage of Splunk over competitors like IBM QRadar is its superior device integration capabilities. With Splunk, we can seamlessly integrate and coordinate data from various sources, enhancing our analytical capabilities.

What needs improvement?

I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options. Additionally, enhancing support services with more technical personnel is essential. Delays in responses from the technical team can pose challenges for both vendors and clients, especially considering that Splunk applications and machine solutions are critical assets. Splunk's pricing may pose a barrier for some users, but if it becomes more competitive, it could attract those currently using IBM QRadar or similar solutions. Additionally, considering the trend towards migration to Microsoft Sentinel, which offers a comprehensive suite including identity management and EDR coverage with Microsoft Defender, Splunk could benefit from offering similar modules. In Microsoft Sentinel, they offer a separate identity management module, which I find particularly valuable. Any anomalies detected within identity management trigger alerts, providing enhanced security.

For how long have I used the solution?

I have been working with it for two years.

What do I think about the stability of the solution?

It provides good stability capabilities.

What do I think about the scalability of the solution?

The scalability of Splunk, particularly when implemented as an enterprise solution, is notable. While we work with a limited number of clients, typically five to six, they are spread across various locations, including the US and Pakistan. From a maintenance perspective, our operations are based in Pakistan. Our clientele predominantly consists of customers from Gulf countries, and we also extend our services to clients in the US.

How are customer service and support?

There have been instances where the response time from Splunk's support team has been slower in comparison to others. I find IBM QRadar and similar solutions to have more efficient support teams. I would rate it five out of ten.

How would you rate customer service and support?

Neutral

What about the implementation team?

Our deployment team handles both deployment and support services, including maintenance responsibilities.

What was our ROI?

It offers a return on investment for our company.

What other advice do I have?

Overall, I would rate it eight out of ten.

Rock-solid reliability with great threat intelligence management and good visibility across environments
Pros and Cons
  • "The feature that we use the most is the correlation search engine within ES."
  • "It is a hugely complicated product."

What is our primary use case?

I've been building SOCs for multinational banks across Asia and Australia, the Middle East, and right now in the United States.

It's the tool that we use to build SIEMs to meet logging requirements and to identify security issues across larger states of data sets.

How has it helped my organization?

We wanted to give our analysts visibility in near real-time to problems as they occur. That's the goal. 

By using the frameworks that we've adopted, like MITRE ATT&CK and the coverage mapping, we're able to show the divisions that we have in our detection environment. And we map that across with our prevention layers just to describe to the business the deficiencies we have. We can show, for example, these are the areas we can't see since we don't have logging for them, and or these are the areas we can spend more time on to draw down risk due to the fact that, while we have the logging, we haven't got the searches and correlation searches in place. That would perform detection behind the preventative controls. So it gives us a guide as to where we can spend time better.

What is most valuable?

The feature that we use the most is the correlation search engine within ES. That is the one we use. Absolutely the most. There are a lot of other features in there, however, that's the one we use.

Our organization does monitor multiple cloud environments. It's not "easy" per se. I'm a Splunk-certified architect. I've got 30 years of experience. If you've got 30 years of experience and you're a Splunk-certified architect, it's easy. If you haven't, you've got no chance.

Splunk Enterprise Security's visibility into multiple environments, for example, cloud, on-prem, and hybrid is good. Splunk doesn't care. It's as easy on-prem as it is on the cloud, as it is hybrid. I've built up all three individually and separately depending on the environment.

The insider threat detection capabilities for helping our organization find unknown threats and anonymous user behavior are okay. It can do it, however, it is not out of the box a UEBA. It doesn't pretend to be. Splunk has a separate product for that which is not the enterprise security suite. That said, if you enable the access domain correctly within ES, it gives you really good insight into what your Insight users are doing. That's what the access domain is. However, it doesn't have the advanced features that you would expect from your UEBA product as it is not one.

We use the threat intelligence management feature. My impressions of the actionable intelligence provided by the threat intelligence management feature are mixed. We import anomaly threat intel into the Splunk ecosystem to do that. We use the framework that Splunk provides, and we supplement it with the threat intel from a third party, and that works really well.

We use the MITRE ATT&CK Framework. We’ve mapped all of our detections around that Miter framework. There's there's four frameworks built in, and we chose Miter. It just makes more sense. You only pick one. There’s no sense in picking more than one.

It’s helpful to uncover the overall scope of an incident. If you've done the work to map your MITRE ATT&CK Framework into the product, then you have a hit against a MITRE ATT&CK technique. Then at least you know where it is in the MITRE ATT&CK framework so that you can describe it as a common frame of reference with a third party. However, it doesn't necessarily give you an idea of the scope. It requires more effort. That said, it's certainly a really good starting guide as to where you are.

Splunk Enterprise Security is okay for analyzing malicious activities and detecting breaches. It's only as good as the operators that use it. Out of the box, it doesn't do anything. You have to put the work in to make it do that. I can't begin to say how useful it is when it's first configured. You need to spend a lot of time working on your environment to make it do that.

It helped us detect threats faster. Without it, you can't check anything. It's too complicated.

The solution has helped us speed up our security investigations. Without it, you don't have investigations. Also, with the alerting itself, Splunk becomes best of breed.

What needs improvement?

Enterprise Security hasn’t helped us reduce our alert volume. The analysts have, however.

We do all of our enterprise security on-prem. We avoid the Splunk Cloud solution since we want the flexibility to build our own. It is a hugely complicated product. Obviously, anything that they could do to make it easier would be ideal. 

For how long have I used the solution?

I've used the solution for over ten years. 

What do I think about the stability of the solution?

It's rock solid. It never failed. Having resilience in our organization is fundamental to our security position. 

What do I think about the scalability of the solution?

We're a multinational and have Splunk in the UK and US. We have 2,000 employees, and 2,000 endpoints, at the employee level. We also have around 12,000 production endpoints and it runs across a multi-cloud hybrid that includes GCP and AWS. It also has a tiny on-prem footprint.

You can horizontally scale someone instantly. I've never been afraid we would exceed horizontal requirements. 

How are customer service and support?

We don't use technical support. 

Which solution did I use previously and why did I switch?

I did not previously use a different solution in this company. 

A long time ago, the company replaced ArcSight with Splunk. 

How was the initial setup?

The initial deployment was complex. 

Our strategy has been to avoid clustering for searching and to build a significantly larger virtual machine for running the ES environment as a stand-alone. It's got 128 cords and 256 Giga RAM so that it can run inside itself and not have to cluster since a cluster adds too much complexity.

We only need one person, myself, to deploy the solution. I'm a Splunk certified architect and I have 15 years of experience doing nothing but Splunk. 

The solution does require some maintenance. We have seven people in total handling maintenance. 

What was our ROI?

I have witnessed ROI. However, luckily, our center does not have to pay for the license. 

What's my experience with pricing, setup cost, and licensing?

We get enterprise licensing via Intuit, our parent company. The licensing is horrendously expensive. 

Which other solutions did I evaluate?

I did not evaluate other options. This solution was in place when I arrived. 

What other advice do I have?

I'm an end-user.

If you are looking for a cheaper option, you probably don't have a focus on security or have a risk that you care about enough to purchase a premium solution. If you look at the Gartner roadmap, Splunk is a clear leader, and it's always at the top right quadrant. Everything else is attempting to catch up to Splunk. There's no one else in front of it. If you choose something like Elastic or Sumo, your company doesn't place an emphasis on security. 

I'd rate the solution nine out of ten. It's a lot of work. Almost nothing works out of the box. You have to invest in it for three to five years at a minimum.
