For how long have I used the solution?
I have been using Splunk Enterprise Security for almost six months.
What do I think about the stability of the solution?
Splunk is a very stable platform.
What was our ROI?
My customers feel it's a good investment, but Splunk updated its price models recently.
What's my experience with pricing, setup cost, and licensing?
One of Splunk's two major disadvantages is its high cost. The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.
What other advice do I have?
Splunk has disadvantages such as cost and resource requirements. However, once I invest, it's a powerful platform that ranks number one in SIEM and observability. I rate the product nine out of ten due to pricing concerns and threat intelligence management not being advanced.
I believe Splunk is the top SIEM tool. However, the term "enterprise security" is misused when applied to Splunk. While many vendors claim to offer "enterprise security," true enterprise security should cover all aspects of cybersecurity. Splunk excels in SIEM, SOAR, and UEBA, but it doesn't address other crucial areas like firewalls, PAM, or web/mail gateways. Therefore, Splunk shouldn't be categorized as an "enterprise security" solution. Although Splunk leads in SIEM with its superior visibility and observability, it lacks presence in other essential cybersecurity domains.
Which deployment model are you using for this solution?
Hybrid Cloud
Disclosure: My company has a business relationship with this vendor other than being a customer. Partner
Splunk and Python Engineer at a financial services firm with 10,001+ employees
Improves our ability to handle data from applications
Pros and Cons
- "Splunk's strength lies in its single-page view."
- "Due to its high licensing cost, Splunk is out of reach for many organizations."
What is our primary use case?
As a Splunk engineer, I collect data from various sources, including Universal Forwarder, Heavy Forwarder, DB Connect, and Syslog to monitor application logs. This data is used to create dashboards that visualize application health and identify potential security incidents. Additionally, I configure alerts to notify teams via Slack or email when CPU or memory usage reaches critical thresholds, allowing for prompt resolution. Furthermore, I use Splunk to create KPIs and NDDs for various aspects of the organization, including a custom ITSI service for Microsoft 365. This service monitors child entities like Teams, Outlook, and Edge within a parent application, tracking metrics like team member logins and meetings, CPU usage, and memory usage. All this information is consolidated into a three-page ITSI report.
Splunk Enterprise Security helps us detect malicious activity, such as failed login attempts by unauthorized users. These attempts, whether brute-force attacks or phishing attempts, trigger alerts with detailed information about the incident mapped to the MITRE ATT&CK framework. This allows our security team to investigate and take appropriate action quickly.
How has it helped my organization?
We managed Splunk's large clustered environments, I oversaw data collection from roughly 750 applications via universal deployment clients. This experience, coupled with my nearly six years of Splunk expertise, made monitoring application logs and creating Splunk knowledge bases straightforward tasks. While processing task cut-off tickets from the application team could be time-consuming, the actual monitoring itself was easy to manage.
The end-to-end visibility provided by Splunk is important because our company uses applications like K-Connect and Splunk to monitor user activity across different sectors. Having previously worked in both healthcare and finance, I'm familiar with how this process works. We access user information including personal data to track their activity from start to finish within our systems. Splunk allows us to mark specific user data points for further analysis, ensuring we have a full view of user or patient activity within each organization we serve.
Splunk helps me find security events across multi-cloud and on-prem platforms. I would identify missing data by checking the last hour's timeframe (span=1h). If on-prem or cloud data was missing, I'd investigate which logs weren't being ingested, whether an indexer was down, or if a forwarder wasn't sending data. Additionally, I'd check if the application or event log volume was overwhelming the universal forwarder, requiring a queue to process the data effectively.
Splunk improves our ability to handle data from applications. This data is often unstructured or unavailable in a usable format. To make it usable, we used to normalize the logs manually through back-end commands and edit various Splunk consoles and platforms. This process transformed the data into a structured, human-readable event format, allowing us to extract the information we needed.
We can identify potential malicious activity through Splunk by analyzing database logs with SQL queries. For instance, a high number of failed login attempts within a short timeframe could indicate unauthorized access attempts. Additionally, with multi-factor authentication systems like Duo, a user logging in from two geographically distant countries within a short period might be suspicious. To address this, I've developed SQL queries that check for logins within a one-hour timeframe across different countries. These queries trigger alerts on a dashboard, allowing IT to investigate the user's IP address and determine if the login is legitimate.
Splunk has significantly improved our business resilience by providing a single pane of view for all our data. This visualization allows us to monitor for anomalies, including unusual application activity, unauthorized executables, and suspicious shell scripts running on both Linux and Windows servers. By triggering alerts for these events, Splunk empowers our organization to proactively identify and address potential threats, ultimately improving overall stability.
Splunk allows us to easily check the data for malicious activity. It also helps reduce the alert volume by allowing us to set thresholds for alerts. For example, we only receive an alert when the CPU usage exceeds 90 percent or the number of failed logs is more than 15.
Splunk helps us investigate by providing relevant context from system logs. We can search the Splunk logs for specific applications and timeframes, and then examine all the data fields for suspicious activity, failed login attempts, or any other anomalies.
It helps security teams investigate threats faster by providing a central platform to collect and analyze data from various security applications. This focus on enterprise security allows teams to identify and respond to threats across the organization, leveraging frameworks like MITRE ATT&CK to match attacker techniques and tactics.
What is most valuable?
Splunk's strength lies in its single-page view. This interface allows us to explore all our data, build dashboards with alerts, and visualize real-time information through various charts like column, bar, and pie formats, providing a full user experience.
What needs improvement?
Due to its high licensing cost, Splunk is out of reach for many organizations. Making their licensing more affordable would open up Splunk's solution to a wider range of users.
For how long have I used the solution?
I have been using Splunk Enterprise Security for six years.
What do I think about the stability of the solution?
Splunk Enterprise Security is a stable solution.
What do I think about the scalability of the solution?
Splunk Enterprise Security has excellent scalability.
How are customer service and support?

IT Developer/Architect at a government with 10,001+ employees
It integrates well, reduces alert volume, and we can customize the dashboards
Pros and Cons
- "Splunk Enterprise Security allows us to create custom dashboards by changing fonts and modifying widgets."
- "I've noticed that onboarding data from various multi-cloud sources and diverse products, such as security network devices, can be challenging."
What is our primary use case?
We use Splunk Enterprise Security for various security use cases, including writing correlation searches. This has significantly improved both our use cases and correlation searches. We can leverage existing resources, making modifications as needed, rather than starting from scratch each time. Splunk Enterprise Security provides diverse use cases across different environments, including AWS, Azure, and multi-cloud setups, while also integrating with Microsoft Sentinel. Additionally, we can integrate Splunk's service orchestration product for further automation. Overall, this allows us to automate tasks that security analysts previously performed manually, such as reviewing incident dashboards. We can fine-tune alerts based on analyst feedback. Splunk's research team ensures that use cases are updated with the latest security content, enabling us to understand and implement necessary steps while customizing them to fit our company's needs. This is what makes Splunk Enterprise Security so popular; it streamlines processes compared to legacy security products that often rely on manual scripts. Clients, including government agencies and banks, are transitioning to Splunk Enterprise Security due to its reduced training requirements and comprehensive features. Everything is consolidated, simplifying training and certification. Additionally, integrating Splunk's service orchestration product further automates tasks and improves response times. The substantial investment in Splunk indicates its staying power; no other product on the market currently offers comparable capabilities. Cisco's acquisition of Splunk reinforces its potential for success, combining APM, data logging, and security portfolios. In one financial project involving 600,000 users, we were able to monitor all incoming traffic, identify security activities, and distinguish between legitimate and malicious traffic, including phishing attacks and potential identity-based threats. Splunk enables tracking individual identities, crucial for detecting attacks where perpetrators hide behind compromised identities, often leading to data breaches and other security incidents.
We implemented Splunk Enterprise Security to assist with AWS security, which includes GuardDuty, CloudTrail, CloudWatch, and Inspector. These AWS components generate compliance and security alerts, which we correlate and use to create dashboard reports and identify security events for various use cases. We then enable the out-of-the-box use cases and send notable events to the dashboard. The implementation is currently in its early stages.
How has it helped my organization?
Splunk Enterprise Security operates based on incoming data, making monitoring multiple cloud environments relatively simple due to data availability and integration capabilities. Data from cCloudRail, CloudWatch, Azure, and other diverse environments can be incorporated. While occasional patching might be necessary, most integrations are readily available, offering extensive coverage without customization. Specific customizations might still be required, but most functionalities are pre-built, leveraging code developed by Splunk. This efficient approach involves analyzing data from vendors like Palo Alto and applying add-ons to apply code and automate parsing.
Our visibility into various environments depends on how much data we incorporate; therefore, the more we scan, the better our visibility.
Splunk Enterprise Security's insider threat detection capabilities act as a secondary approval and vetting process, helping our organization ensure there are no unauthorized users.
The MITRE ATT&CK framework allows us to identify criticality levels, helping us respond to incidents. We might integrate incident response with a REST API, where a notable event triggers the creation of a ServiceNow ticket. Information flows from ServiceNow back to Splunk, which then feeds other systems, enabling bidirectional incident management. These processes are largely out-of-the-box, as Splunk integrates well with ServiceNow, except for any customizations. We understand the data integration requirements and leverage Splunk's extensive integration capabilities.
Splunk Enterprise Security does a good job of analyzing malicious activities and detecting breaches. The amount of information the research and threat detection teams receive from Splunk enables faster threat detection of up to 60 percent, eliminating the need to consult numerous sources. This efficiency is a key benefit of Splunk, as its significant investment in security allows for expedited processes.
I have seen the older legacy product where they have this manual process to identify issues, run scripts, try to identify the output, and then go through ten systems to collect data. This could take days. Now, with Splunk, we have everything correlated with multiple use cases, and we have a correlation search between multiple systems, along with application data. Splunk Enterprise Security can stitch all this information together and show it in a single pane of glass, which makes decision-making faster and allows us to focus on the relevant issues instead of wasting time on non-relevant ones. They have done this well.
Splunk Enterprise Security significantly reduced our alert volume. The initial challenge was dealing with a legacy IBM system that generated a massive amount of unfiltered noise, making it difficult to identify relevant events to send to the incident dashboard. This process was time-consuming and inefficient, and the value of the system wasn't apparent. To address this, we fine-tuned both the SOAR system and Splunk by applying filters and conditions to focus on relevant data. Ultimately, Splunk reduced the alert noise from 1,000 events in two hours down to ten, which were then grouped into a single notable event. Despite potentially having hundreds of background events, Splunk condensed this information into a single, actionable item, allowing us to focus on investigating the most relevant issues.
Splunk Enterprise Security accelerates our security investigations by reducing noise, allowing us to focus on relevant use cases. Everything is categorized as high, medium, or low priority, and people immediately start investigating high-priority issues connected to PagerDuty. Sometimes, this leads to on-call situations, sometimes immediate action. Service orchestration and playbook scenarios enable automated responses, like instantly blocking unauthorized access to a system. The possibilities for security use cases with playbooks and service orchestration are vast, and I'm excited to explore them further in the coming days.
The dashboards and reporting capabilities help to aid our security analysis.
We have integrated Splunk Enterprise Security with various services to streamline our security operations. This integration allows us to leverage diverse data sources for creating lookups, data models, knowledge objects, and regular expressions. By automating the development of use cases and regular expressions, we can apply them to data more efficiently, enabling faster implementation and analysis. This approach enhances our ability to detect and respond to security threats effectively.
Splunk Enterprise Security has enhanced our organization's security posture by providing comprehensive security compliance dashboard reports.
What is most valuable?
I appreciate how Splunk Enterprise Security connects users to the research team and threat documentation, providing access to current events impacting other clients, security vulnerabilities, and relevant use cases. The platform's daily updates offer valuable insights for enhancing our security posture.
Splunk Enterprise Security allows us to create custom dashboards by changing fonts and modifying widgets. Those familiar with XML coding can further personalize dashboards to align with frameworks such as MITRE. Alternatively, we have the option to use the pre-built dashboards.
What needs improvement?
I've noticed that onboarding data from various multi-cloud sources and diverse products, such as security network devices, can be challenging. Although Splunk has simplified data onboarding with features like data managers, they need to improve their out-of-the-box parsing capabilities. While they've made significant progress, covering about 70 percent of common products, there's still a 30 percent gap where manual configuration is required. This forces us to spend time understanding and writing custom parsing rules instead of focusing on data analysis. With Splunk's recent acquisition by Cisco, I'm hopeful they will prioritize enhancing this functionality and increasing their coverage to 90 percent or more.
I want to see Splunk Enterprise Security dashboards incorporate more features, such as out-of-the-box AI and user behaviour analytics, which are accessible within a single dashboard.
The technical support response time has room for improvement.
For how long have I used the solution?
I have been using Splunk Enterprise Security for three years.
What do I think about the stability of the solution?
Splunk Enterprise Security has stability issues, especially with large data volumes, increased data intake, complex dashboards, custom models, and processing that significantly impact performance. Many customers experience this; even with demos using small datasets, performance degrades with millions of data points. This necessitates capacity planning, dedicated teams, and enforced best practices. These practices include restricting complex searches, blocking problematic users, and providing training to prevent performance degradation. Constant vigilance and proactive measures are crucial to maintaining a stable Splunk Enterprise Security environment. I would rate the stability of Splunk Enterprise Security five out of ten.
What do I think about the scalability of the solution?
I would rate Splunk Enterprise Security's scalability six out of ten. We need to add more shared CPU memory and increase the capacity, and scaling requires a lot of planning and effort.
How are customer service and support?
Splunk's support quality has declined in the past five years. Response times are now slower, and resolving an issue can take weeks. Submitting a ticket and connecting with the appropriate support agent often requires numerous emails and calls.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
To improve security coverage and user experience, we replaced our outdated legacy solution with Splunk Enterprise Security.
How was the initial setup?
Our Splunk Enterprise Security cloud deployment utilizes a DevOps approach with a fully automated CI/CD pipeline. This automation has significantly improved our deployment speed, reducing the process from a week to a few minutes. Changes are made in the development environment and then automatically pushed to production after a click-through approval process. This streamlined workflow eliminates the previous manual process and associated delays, resulting in a faster and more efficient deployment cycle.
What's my experience with pricing, setup cost, and licensing?
Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises.
What other advice do I have?
I would rate Splunk Enterprise Security eight out of ten.
Splunk is widely used across larger organizations. While large organizations often have extensive teams dedicated to Splunk projects and upgrades, smaller organizations can also use Splunk, taking advantage of more affordable pricing options like the free tier for limited data. Cost isn't a significant concern for larger organizations, who prioritize Splunk's security features and are willing to invest in its capabilities.
Splunk Enterprise Security is deployed across all departments, processing millions of data points. Over 500 people manage this data: building dashboards and reports, working with Enterprise Security, discussing use cases, and creating custom data models. This represents a massive effort for any large organization where every department utilizes Splunk.
Government departments are transitioning to Splunk, with daily onboarding increasing the current user base of 5,000.
Because the deployment is cloud-based, the Splunk DevOps team handles maintenance.
Splunk offers a resilient SIEM solution with comprehensive capabilities for research and a wide range of use cases. It is constantly updated, ensuring it remains a valuable and comprehensive SIEM package.
I recommend Splunk Enterprise Security. It is an excellent tool widely used by many organizations, making it a valuable choice for security information and event management.

Principal Cyber Security Engineer at a financial services firm with 5,001-10,000 employees
Provides users with insights and the ability to send alerts to analysts
Pros and Cons
- "The benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers."
- "I think the only thing lacking is that there are some answers that I couldn't find about the tool without reaching out to support, and it had to be escalated to the engineering team."
What is our primary use case?
I mostly use the solution in my company for incident response, ticket management, and integration with other endpoint products.
How has it helped my organization?
The benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers.
What is most valuable?
The most valuable feature of the solution is the correlation searches. The one-stop shop shows me all my insights, and alerts, and can send alerts to my analysts.
I would say it is fairly important for my organization that Splunk Enterprise Security provides end-to-end visibility in our environment. At the same time, my company has other products that cover the observability piece. From a security perspective, we use data outside of our security data to piece together the whole picture. I think our company's perspective is that no matter how we get the whole picture, we will do it, even if it is from outside Splunk Enterprise Security. I think Splunk Enterprise Security plays a major role in this.
In terms of Splunk Enterprise Security for helping our company find any security event across multi-cloud, on-premises, or hybrid environments, I would say that it is great once you get past the learning curve. The learning curve is higher than normal.
I think Splunk Enterprise Security has helped improve our organization's ability to ingest and normalize data in a great manner. Splunk is a great product and provides these features, but not so much when it comes to identifying and solving problems in real-time because there are always data delays. There is always onboarding, mapping, creation of correlation search, and then enabling Splunk ESCU part. It works in a general sense and not on a real-time basis.
In terms of whether Splunk Enterprise Security has helped reduce alert volume, I would say that it is the only active SIEM tool my company is currently utilizing. Reducing alert volumes involves tuning up certain areas of the engineering team. If I look at the product alone, I would say it can help reduce alert volume. If I consider the learning curve, I would say that you have to learn how to tune it the right way with the help of professional services or experts. You need to utilize your resources, which I think is the best way to do it.
Splunk Enterprise Security provides our company with relevant context to help guide our investigations since the correlation searches with the enriched data do help gain insights on all of our investigations. At the current point, we are still trying to get past the tool's learning curve so that all of our analysts and everyone on the security team can utilize the tool the best way they can. The more they learn, the better it gets, so currently, we are doing our best.
Splunk Enterprise Security helped reduce the meantime needed to resolve our issues because we have all our data in a centralized location and mapped to a data model. As long as we know what detection and data we are looking at, we can go to our data model and figure out where the issue lies.
Splunk Enterprise Security's ability to help improve our organization's business resilience revolves more around observability. Our company recently migrated to Splunk Cloud, and I think we have more hands-on experience with the ingestion side than ever before. I think it is a lot easier for us since we moved to Splunk Cloud as we don't have to focus on maintaining the infrastructure so much, and we can focus more on the data. I think this is outside of Splunk Enterprise Security's scope and falls under Splunk Cloud's capacity.
Speaking about Splunk's unified platform helping consolidate networking, security, and IT observability tools, I would say that my company is not there yet.
What needs improvement?
In the next release, I want Splunk to offer more openness to integrations with other products that may be more of a preference for my incident response teams.
For how long have I used the solution?
I have been using Splunk Enterprise Security for five years. I am an end-user.
What do I think about the stability of the solution?
In terms of stability, if configured correctly, it works great.
What do I think about the scalability of the solution?
With Splunk Cloud, I think using the tool's scalability feature is easy since one can just call the product's support team.
How are customer service and support?
The solution's technical support is great since they have been very responsive and very attentive while answering all my questions. If the support team can't answer my questions, they escalate it to their engineering team.
I have had nothing but good things to say about Splunk's technical team. There have been times when I had to rephrase my questions or when there were communication issues, but the time to respond, escalation, and the attempts in trying to find help and answers from the support team's end have always been great.
I think the only thing lacking is that there are some answers that I couldn't find about the tool without reaching out to support, and it had to be escalated to the engineering team. If this process is the only way I can find answers, I think it is a little bit limiting for an engineer who supports a real-time incident response team. I rate the technical support a nine and a half out of ten.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I have personally not used any other product before Splunk Enterprise Security.
How was the initial setup?
The product's deployment phase was pretty easy to manage since our company has a migration team and support staff. We also had a really good project manager from Splunk to help us, who walked us through every step, and it was a great experience.
The solution is deployed on Splunk Cloud, which runs on AWS.
What about the implementation team?
My company works with Splunk directly to help us with the implementation, and our experience with the product has been great.
What was our ROI?
I have not seen an ROI.
What's my experience with pricing, setup cost, and licensing?
The pricing model is great. You can choose between workloads or volume. I am not part of the conversation about pricing in my organization. I just know what I know about the tool from learning about Splunk.
What other advice do I have?
I rate the tool a ten out of ten.
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

SOC Technical Lead at a educational organization with 1,001-5,000 employees
Gives visibility into what's happening across the network and allows us to dig deep
Pros and Cons
- "Being able to aggregate detection and alerts from various sources is valuable. Like everyone else, we have a wide range of tools in our shop. We are able to stop at one spot and look at all the data. All the data is able to come through, and we can then jump from source to source or index to index. We can dig deep whenever we need to and get a good high-level understanding."
- "The first thing that comes to mind is a little bit of UI improvement. It sometimes can be a little bit buggy or it can be a little bit slow, but that varies from customer to customer."
What is our primary use case?
I am a SOC lead, and we use Splunk Enterprise Security for alerting and working on incident review and incident response.
We have a hybrid environment. We have multiple clouds, and I am not sure if I know all of them. We have Azure Labs that we run for our students. We have cloud infrastructure. We have cloud applications on which we need visibility.
How has it helped my organization?
It is incredibly important that Splunk Enterprise Security provides end-to-end visibility into our environment. Especially being someone who goes through and reviews the work that my analysts are doing, I definitely need to be able to see what is happening all across different domains of our network.
We work for a large university, and we have different tenants. We have our students, we have our employees, and then we have our faculty as well. We definitely need to see what is happening across the domains and across all of those different tenants.
It saves so much time for the analysts, and it empowers analysts to carry out and triage an investigation, wherever needed. It is incredibly hard when you are working with different sources. I am sure everyone else knows that you cannot expect your analysts to be on the same page a hundred percent at the time. They might say, "Hey, I am going to go into this tool and look at these alerts here, or I am going to look at these learnings from this tenant." We need to be looking at all of those sources and all of those domain tenants at once. Being able to see that across the board and not having to jump through hoops to get the data that we want is extremely valuable. I do not have metrics for how much time it has saved because I do not know our life before Splunk. I know that it has done a great deal in saving time, and now with SOAR, that is exactly what we are looking into. We are looking into how we can empower that even more by combining it with Splunk Enterprise Security.
Splunk Enterprise Security has helped improve our organization’s ability to ingest and normalize data. Splunk is definitely a leader. I cannot imagine leaving and going to another toolset and losing the capabilities that I have and the knowledge that I have. One of my favorite parts is that Splunk really does work. It seems to me that they work with actual users on a regular basis, so they know the pain points and they know what our issues or our primary concerns are.
In the beginning, it did not help to reduce our alert volume, but over time, it has definitely reduced that. Something that I am working on primarily with our SOC right now is increasing our alert volume because we are at such a low rate because of the work that we can do with Splunk's capabilities. We are looking into what areas in the network we are not alerting on. We have these out-of-the-box solutions, but there is more that we can build on. It is empowering our analysts to be SOC analysts, but the more advanced employees can work towards the threat detection engineering side or SOAR playbooks development side or even just on the backend of setting up and working with the configuration.
I wish I knew the metrics for the reduction in the alert column. I do not have any approximation, but our SOC is very manageable. We are a small team, and the number of alerts varies. On average, we get about 300 alerts a day on the high end and 150 alerts on the low end. If it is a very slow day, such as a vacation for everyone, and we do not have a lot of activity going on in the network on our endpoints, it is very manageable for a small team. Our SOC team has four full-time employees, and then we have intern/student workers because we partner with the university. We have three of them. Overall, there are seven, but, of course, students are only able to work a maximum of 15 or 18 hours a week or something like that, so the amount of man-hours that we have is pretty low.
Splunk Enterprise Security provides us with the relevant context to help guide our investigations. There could be a little bit more, but that also depends on the analysts and where they are in terms of maturity. I have a lot of capability to go and expand what I need to, but others do need a little bit more guidance. It is not easy on the first look for someone who has never done it before, but after being taught or learning about it themselves, it is pretty easy. It can still do a whole lot. If we are looking at an anonymous login, we are getting context from different sources. If there is an activity that is going on in the host machine, such as we have some login from Russia, which has never happened before, there is a firing of alerts from the EDR. We can see our email gateway firing alerts regarding their account. That allows us to contextualize and correlate the activity very easily.
Splunk Enterprise Security has helped improve our organization’s business resilience. We are able to take action immediately when we need to. Especially with risk-based alerting, we are able to understand what needs attention right now. We do work with young junior analysts a lot, and we are able to teach them how to identify what needs action right now or what needs to be investigated or triaged immediately. We are basically protecting our crown jewels first rather than some low-hanging fruit that we see everyday, but we cannot take a look at them because we have some important things going on in our network.
What is most valuable?
Being able to aggregate detection and alerts from various sources is valuable. Like everyone else, we have a wide range of tools in our shop. We are able to stop at one spot and look at all the data. All the data is able to come through, and we can then jump from source to source or index to index. We can dig deep whenever we need to and get a good high-level understanding.
What needs improvement?
The first thing that comes to mind is a little bit of UI improvement. It sometimes can be a little bit buggy or it can be a little bit slow, but that varies from customer to customer.
They can continue building out the Splunk community. They can give incentives for customers to collaborate and expand on what they are working on but also provide the tools to do that. There are good resources such as Splunktern. I love the Splunk education and training platform. It is amazing, but I wish there was a little bit more. Especially with the training and applications, they should give us real-world use cases and a little bit more specific scenarios. Splunk is doing a much better job than a lot of other organizations or technology platforms, but they can give more information. I know a lot of my Splunk users do not even realize the things that they can do. On the user end or analyst end, they need to be more proactive by giving more of a heads-up. For example, I found out about Splunk research today. I have been using Splunk for two years. I wish I had known about that more. They can reach out more. The incentives can be anything. Some people love stickers, and some people love shirts. They can create that community a little bit more.
For how long have I used the solution?
I have been using Splunk Enterprise Security for two years.
What do I think about the stability of the solution?
I do not have much to compare it to, but it is stable. We hardly have any issues, and if we do, they are intermittent.
What do I think about the scalability of the solution?
The growth that we have seen in my time with our team has not been so much. However, we are adding more tools or trying to gain visibility into different areas of our network or applications that have already been there. Being able to throw some logs in and figure out that we should be monitoring this has been painless. We can just forward them all over. It takes an hour or so. We get the answers and the visibility that we need.
How are customer service and support?
I have not used it very often. I have used it once or twice, but I would say that the engineers I have worked with have been extremely knowledgeable. They have helped so much. We were working on SOAR, and we were pretty new to it as a SOC. We were able to work all of that out with a Splunk engineer on a call. They were able to answer our questions. They knew our needs and goals, and they were able to guide us to meet those. That has been very effective for us. I would rate them a ten out of ten. I have not had any bad experiences.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We have had Splunk since I have been in this company.
What was our ROI?
Specifically, I cannot say what return on investment we are getting. However, when we look at other products, we know we are not going to have the same capabilities and we are not going to have the same response times and correlation capabilities. Even working with other vendors and getting their logs into Splunk can be a nightmare, and that is enough to make us say that we do not want to buy their product.
Which other solutions did I evaluate?
Personally, I have not evaluated other solutions. We do have some friends and family connections who use other solutions. Based on their stories, we will continue using Splunk.
What other advice do I have?
I would rate Splunk Enterprise Security a nine out of ten. If it were a ten, it would do my job for me.

Works at a insurance company with 1,001-5,000 employees
Offers flexible data ingestion and searching capabilities
Pros and Cons
- "What I appreciate the most about the product is the flexibility with data ingestion and searching, which is very powerful; you can do whatever you want with it."
What is our primary use case?
My use cases are SIEM basically, which means using Splunk Enterprise Security as our SIEM effectively. We are taking all of our data from on-prem and some of our cloud services and importing them into Splunk Enterprise Security, then creating and generating alerts and reports based on some of our security use cases.
What is most valuable?
What I appreciate the most about the product is the flexibility with data ingestion and searching, which is very powerful; you can do whatever you want with it. We were able to see its benefits pretty much right after we got it implemented.
What needs improvement?
The UI sometimes can be laggy and not responsive. Additionally, some places need to be refreshed from a UI visual standpoint; I think they're starting to get better at that. Splunk Enterprise Security has come along much better since when we started looking at it.
We use the cloud version, the Splunk Enterprise Security Cloud version, so we don't have access to a lot of the back-end functionality. Not having used it on-prem and just going straight to the cloud means there are some nuanced differences in how things are managed. If you look up documentation it says, 'You need to update this file,' and I cannot access that file. The translation between on-prem and cloud for some of the configuration elements needs clarification.
For how long have I used the solution?
I have been using it for a year and a half.
What do I think about the stability of the solution?
Stability and performance are pretty good for the most part, with only the UI lagging sometimes. Depending on the screen, it can take a while to load.
What do I think about the scalability of the solution?
Regarding scalability, it's hard to really say as we haven't had to build out anymore since implementation. However, we've been able to input most everything into it, and we don't have to do any rescaling as it happens automatically, which is beneficial.
How are customer service and support?
I have contacted their technical support, and they are pretty good for the most part. There have been a few times when things were prolonged, but overall, the support has been good.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I have not used any alternative solution.
How was the initial setup?
The initial deployment was pretty easy for our company. It took us three months to fully deploy it, and we are maturing as we've been progressing. We have had many transitioning use cases, but getting the data in was pretty straightforward.
Splunk Enterprise Security doesn't require much maintenance on our end, just patching and occasional app updates. Most of it is just configuration work and not application updates, which is beneficial.
What about the implementation team?
Our whole team manages it right now; it's not a one-person job.
What's my experience with pricing, setup cost, and licensing?
I am somewhat familiar with the pricing. Generally, it seems expensive, though I don't think it's the most expensive option. Sometimes it can be confusing to determine the best way to utilize everything based on our pricing tier.
What other advice do I have?
I would rate Splunk Enterprise Security an eight out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Other
