Has accelerated detection workflows and enabled timely alert triage across multiple data anchors
Pros and Cons
  • "I would assess the stability and reliability of Splunk Enterprise Security as very reliable and very stable."
  • "Splunk Enterprise Security can be improved by addressing the content management interface, which is very outdated, slow, and clunky; sometimes we think things are saved and they haven't."

What is our primary use case?

As a threat detection engineer, my main use case for Splunk Enterprise Security is to create content to find anomalous activity in our environment. Splunk Enterprise Security, via the content management interface, allows us to create correlation searches, take advantage of summary indexes where we can correlate multiple findings per host, per user, whatever anchor point you want to use, and get those alerts to our analysts in a timely manner, where they can be triaged based on alert severity and criticality.

What is most valuable?

The notable feature of Splunk Enterprise Security, which in version 8 is going to be called "findings," is the ability to send notables, and all the actions that can be chained with the notable when you actually have a hit or a finding.

The ability to quickly automate detections based on alerts or intelligence that we operationalize in the environment benefits my company, as we get that alert sent to the appropriate parties and put in front of the analysts quickly, allowing for triage and the ability to group the alerts together instead of just always looking at a single finding.

What needs improvement?

Splunk Enterprise Security can be improved by addressing the content management interface, which is very outdated, slow, and clunky; sometimes we think things are saved and they haven't. Being able to edit saved content and saved searches in batch, such as when you have a log source and a field changes, is a pain point right now since you have to go in and basically update all of them unless you do some kind of Eval on the ingestion side; that's probably the biggest pain point with it right now.

What do I think about the stability of the solution?

I would assess the stability and reliability of Splunk Enterprise Security as very reliable and very stable.

What do I think about the scalability of the solution?

Splunk Enterprise Security scales very well with the growing needs of our company, although there are definitely some things that are behind the times, such as some of the limitations out of the box on KV Stores, lookups, and some of the commands, the MV line of commands and some of the limitations there. Hopefully, with the advent of all the cool AI and ML capabilities coming down in the 8 series, many of those limitations will be eliminated.

How are customer service and support?

Regarding customer service and technical support, I don't generally submit support tickets, however, I have on a few occasions. It's usually our Splunk engineering team.

We have bimonthly meetings with our account representatives, and we have some sort of on-call technical staff that are assigned to our company and our contract, and they've all been excellent; wonderful people to work with.

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

Prior to adopting Splunk Enterprise Security, I used another solution that does similar things, and over the course of my career, I've used a couple of different solutions, peer solutions with Splunk, but Splunk Enterprise Security is the best.

It really comes down to the versatility and how powerful it is; I have never worked with another platform where I can do as much for as many teams, not even just security, which is my primary focus, and the value that you can get out of it, I've never seen a platform that versatile.

What was our ROI?

From my point of view, the biggest return on investment when using Splunk Enterprise Security is keeping our company safe.

What other advice do I have?

The advice I would give to other companies that are considering Splunk Enterprise Security is that if you've never used Splunk, it can be a little daunting at first, learning a new language, Splunk SPL. That said, it's worth it.

The cycle time that's going to be taken in training and upskilling, once your staff is familiar with that, and you don't even have to do a lot of training, just a couple of the basic classes from Splunk University to get proficient, it's going to open a lot of doors.

On a scale of one out of ten, I rate Splunk Enterprise Security a nine out of ten.

Centralized logging has simplified root-cause analysis and improves productivity across apps
Pros and Cons
  • "Managing logs is very easy with Splunk Enterprise Security."
  • "One thing I would like to see improved in Splunk Enterprise Security is a better user manual."

What is our primary use case?

Our main use cases for Splunk Enterprise Security are to find the root cause of any applications, to see the dashboards, to see the logs, and to centralize some logging systems.

What is most valuable?

Managing logs is very easy with Splunk Enterprise Security. Earlier, we were using DataDog and before that, we were also using our own tool, 24/7, to maintain logs and everything. In that, we faced many issues maintaining logs from many applications because we are managing many applications right now. So it was very tough, and when we were introduced to Splunk Enterprise Security, we used it, and it became very easy to maintain. It is easy to have control over it.

The main benefits I have seen from using Splunk Enterprise Security are mainly two things: the pricing and the manpower. Right now, we do not have to worry about the time if we encounter any issues. Recently, one of our customers raised an issue that the application was running very slow. Earlier, we had issues like that, but at that time we had to do so much manual checking everywhere to find the issue. Right now, if we get an issue regarding this, it is very easy to understand the root cause.

What needs improvement?

One thing I would like to see improved in Splunk Enterprise Security is a better user manual. Right now, it is pretty tough for any newcomer or new user to understand everything because there are no specific areas for them to learn from.

From a features perspective, an enhancement I would like to see is a better learning aspect. The AI feature is great, but I believe enhancing the learning part for any new user would be beneficial.

For how long have I used the solution?

We have been using Splunk Enterprise Security products for the last eight to nine months, but I have been onboarded on this in the last six months.

What do I think about the stability of the solution?

The stability, reliability, and performance of Splunk Enterprise Security are pretty good. Now we are very stable with many production systems, and Splunk Enterprise Security is also scalable if we want to expand further.

How are customer service and support?

I would evaluate the tech support team as good.

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

I previously used different products and solutions like in-house technologies and DataDog.

How was the initial setup?

The initial setup process for Splunk Enterprise Security was somewhat challenging. As I mentioned, it lacks a specific user manual, making the initial setup tough, but now we are hands-on and comfortable with it.

What was our ROI?

Regarding ROI, while I cannot speak specifically about the investment, I can say that the returns are good. We achieve one hundred percent productivity utilizing Splunk Enterprise Security to create multiple dashboards and find various issues.

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

On the pricing aspect, I find the setup cost and licensing of Splunk Enterprise Security to be relatively cheaper compared to what we used earlier. I can say that what we are paying is worth it based on the value we receive.

Which other solutions did I evaluate?

We decided to switch to Splunk Enterprise Security because of the ecosystem. We are also using Splunk Cloud, and we have a good relationship with Splunk. The pricing compared to what we were using earlier is worth it.

The key differences, apart from pricing, are the visibility and observability. We did not get good visibility with the previous tools, but now we have a very clear view, which is why we switched to Splunk Enterprise Security.

What other advice do I have?

My advice for anyone considering Splunk Enterprise Security is to understand the basics of logging systems first and determine your use cases before building specific functionalities in Splunk Enterprise Security.

We have recently upgraded to Splunk Enterprise Security 8.0, and we are evolving everything now. We are evolving frameworks and many other things within it. I would rate this review an 8.5 overall.

Which deployment model are you using for this solution?

On-premises

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

AI-driven threat detection has transformed investigations and reduces false positives for analysts
Pros and Cons
  • "The AI-driven detections have improved the accuracy of my investigations significantly, reduced my mean time to detection by about 30 percent and my mean time to resolution by about 40 percent, and contributed to faster, more efficient threat detection compared to other SIEM tools I have used."
  • "I rate the technical support of Splunk Enterprise Security as a three. I find it not good because whenever I raise a ticket, they take a very long time."

What is our primary use case?

Splunk Enterprise Security is mainly used for detecting and monitoring log analysis, threat detection, and incident investigation. It is primarily used for failed login detection where multiple login failed attempts occur from the same source IP. Brute force attacks are another common use case. Splunk Enterprise Security use cases can be extended through visualization on data dashboards, setting incident triage, and Windows event log analysis in SOC environments. I use it from a SIEM perspective in my organization.

What is most valuable?

The best features of Splunk Enterprise Security are that it is the leading platform in cybersecurity right now in SOC environments. Business resilience is very useful for real-time monitoring and investigation, which improves our business resilience.

The AI-driven detections have improved the accuracy of my investigations significantly. I have worked with two other SIEM tools: Wazuh and Azure Microsoft Sentinel. Compared to both, Splunk AI is very good. When we mark an alert as a false alert, Splunk Enterprise Security automatically detects it as a false positive. Whenever another similar alert comes through, it automatically takes action, so we will not get that alert on our dashboard again. It automatically handles false positive alerts, preventing clutter on our dashboard.

It has reduced my mean time to detection (MTTD) by about 30 percent and my mean time to resolution (MTTR) by about 40 percent. Our SLA has reduced from fifteen minutes to ten minutes, which is very helpful because we are raising alerts within ten minutes.

Risk-based alerting provides significant value. When we raise an alert, we provide the incident classification as either true positive or false positive in Splunk and also in the ticketing tool. If an alert is a false positive, Splunk's AI takes care of this and tells us whether we want this alert to show to the SOC team or not. The decision depends on AI analysis.

The assessment of the threat topology and the MITRE ATT&CK framework in Splunk shows that Splunk already maps MITRE ATT&CK with incidents. Whenever an alert comes, the AI configures it to that framework. For investigation purposes, I check the process tree to see how the alert originates and where the malware is going to end. This is very good for threat investigation.

Splunk Enterprise Security has become at least forty to fifty percent faster at detecting threats compared to Azure Sentinel. It is very fast for detecting alerts.

It has contributed to the reduction of analyst burnout and fatigue because it reduces our alerts. If we raise an alert on Splunk, it takes care of them through AI. False positive alerts will not show up, preventing mess for our team. Our threat hunting team and forensic team handle the true positive alerts, while false positives are automatically taken care of by AI.

When comparing Splunk with other vendors, I find that Splunk use cases have more power to detect alerts. Azure Microsoft Sentinel has inbuilt over two hundred use cases analytics for their team only, and we cannot create more customized use cases. In Splunk, we can create additional customized use cases, plus there is AI for detection. If we miss some use cases for any logs or events, AI takes care of it and creates its own use case, showing alerts for us. The dashboard is also very user-friendly compared to both.

What needs improvement?

Areas that have room for improvement in Splunk Enterprise Security include user access. When we give access to a new user, it becomes difficult for them to log in and understand the interface. It would be beneficial if there is a demo for L1 users. I also see improvement needed in integration. Currently, we have to manually integrate devices, but I would like AI to take care of it, similar to how SentinelOne operates. This would make the process smoother.

For how long have I used the solution?

My experience using the solution has been two years.

What do I think about the stability of the solution?

Stability-wise, Splunk Enterprise Security is very good. I have not experienced any significant performance issue or downtime.

What do I think about the scalability of the solution?

I rate the scalability of Splunk Enterprise Security as an eight. It depends on how stable and scalable you manage Splunk Enterprise Security for your organization.

How are customer service and support?

I rate the technical support of Splunk Enterprise Security as a three. I find it not good because whenever I raise a ticket, they take a very long time. Even if I call the toll-free number, tickets are pending.

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

I have worked with two other SIEM tools: Wazuh and Azure Microsoft Sentinel. The AI-driven detections have improved the accuracy of my investigations significantly compared to these solutions.

How was the initial setup?

It is very easy to deploy Splunk Enterprise Security compared to both other SIEM tools. Splunk connector is very easy to set up.

The time it takes to install depends on whether we are installing on a Windows or Linux machine or the size of the organization. For a moderate-level company, it usually takes around five days to install everywhere the connectors and endpoints.

What about the implementation team?

When it comes to upgrading Splunk Enterprise Security to version eight point zero, I have a team that handles the upgrade, and it is basically easy to upgrade the version.

What was our ROI?

Combining SIEM, SOAR, and UEBA into a single interface has improved my operational efficiency significantly. Before we integrated SOAR, we usually took fifteen minutes to raise SLA alerts. For analysis, L1 would take ten to twelve minutes to decide if they wanted to raise an alert or not. With SOAR, we have predefined playbooks, so if any inbound connection happens from a malicious IP, it automatically blocks on the firewall. We handle most alerts through SOAR now, which allows us to focus on the more significant incidents like malicious attacks, effectively reducing our response time.

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

Regarding the pricing of Splunk Enterprise Security, I would say it is very expensive for our organization compared to the two others. Wazuh is open-source, and for SentinelOne, we are a partner with Microsoft, but Splunk has a high cost for setup, which is based on the EPS count and storage.

Which other solutions did I evaluate?

When comparing Splunk with other vendors, I find that Splunk use cases have more power to detect alerts. Azure Microsoft Sentinel has already inbuilt over two hundred use cases analytics for their team only, and we cannot create more customized use cases. In Splunk, we can create additional customized use cases, plus there is AI for detection. If we miss some use cases for any logs or events, AI takes care of it and creates its own use case, showing alerts for us. The dashboard is also very user-friendly compared to both.

Enables our team to automate threat detection and prioritize incidents through risk-based alerting
Pros and Cons
  • "I appreciate the Identity and Assets framework the most, as well as the threat analysis framework."
  • "To improve Splunk Enterprise Security, I suggest incorporating more AI features for faster remediation and enhanced responses, allowing users to build more correlation searches quickly."

What is our primary use case?

My main use cases for Splunk Enterprise Security include finding out excessive login failures, any compromised accounts, any compromised emails using phishing tactics with Proofpoint, network anomalies, User Behavior Analysis, and detecting rogue assets.

What is most valuable?

I appreciate the Identity and Assets framework the most, as well as the threat analysis framework. Those are my two favorites in Splunk Enterprise Security, along with correlation searches and the entire incident response workflow.

The Risk-Based Alerting in Splunk Enterprise Security is a great addition to our team, as it correlates data from different sources and adds scores to users or systems, allowing us to make decisions based on risk scores assigned to assets or identities.

Splunk Enterprise Security dashboards communicate our security posture and risk score to executives, including major contributing risk factors, key performance indicators (KPIs), and key risk indicators, which help us make informed decisions about future focus areas.

Splunk Enterprise Security helps our team save time by performing correlation searches automatically, eliminating the need for manual searches. We also utilize SOAR for taking automated remediation responses.

What needs improvement?

To improve Splunk Enterprise Security, I suggest incorporating more AI features for faster remediation and enhanced responses, allowing users to build more correlation searches quickly. Regarding improvements in Enterprise Security, I believe the incorporation of AI would enable Splunk users to spend less time on building correlation searches while still gaining productive ideas.

For how long have I used the solution?

I have over eight-plus years of experience working in the IT sector, with six-plus years of experience collectively working on security and Splunk-related tasks.

What do I think about the stability of the solution?

I would assess the stability and reliability of Splunk Enterprise Security at 90%.

Advanced threat detection has reduced alert fatigue and improves faster incident response
Pros and Cons
  • "Over the course of using Splunk Enterprise Security, it has helped us grow our business and attract more clients due to its low mean time to respond and various analytic engines that help us address threats daily, resulting in positive customer feedback and satisfaction."
  • "There is not much to improve in Splunk Enterprise Security, but points such as deep learning and writing complex queries can be time-consuming, and managing multiple correlation rules can become complex over time, especially with high volumes of log data that can affect performance."

What is our primary use case?

I am still working with Splunk Enterprise Security. We are a reseller of Splunk Enterprise Security, providing it to our customers.

On a daily basis, we use Splunk Enterprise Security for advanced threat and ransomware detection, providing it to our customers for threat detection and ransomware detection, as well as for detecting insider threat anomalies and for continuous monitoring and log analysis.

We provide Splunk Enterprise Security both internally as we are an MSSP, managing our customers and our internal operations.

Splunk Enterprise Security Essentials has contributed to a reduction in analyst burnout or fatigue by addressing the issue of receiving thousands of alerts, with nearly half being false positives, which creates a psychological burden and desensitizes analysts to warnings.

The integration of threat intelligence directly into our TDIR workflow helps us identify false IOCs based on external data, normalizing and correlating it with our internal networks, with Splunk Enterprise Security operationalizing TI feeds through highly structured workflows that manage multiple threat feeds effectively.

Over the course of using Splunk Enterprise Security, it has helped us grow our business and attract more clients due to its low mean time to respond and various analytic engines that help us address threats daily, resulting in positive customer feedback and satisfaction.

What is most valuable?

The most useful features of Splunk Enterprise Security are the data handling, schema flexibility, correlation rules, threat detection engines, and log search capability, which makes it easy to find logs among lots of data, as well as customizable dashboards and risk-based alerting, among other features.

These features are valuable because they help us daily find logs related to our customer requirements and provide reports based on that, making it easier to find data for devices such as networks and Windows.

The most benefits from using Splunk Enterprise Security are the drastic reduction in alert fatigue, rapid incident triage, the ability to find a particular log for specific devices, unified security workflows, data flexibility, instant mapping to security frameworks, and correlation rules, along with anomaly-based rule detection and threat hunting that help us on a daily basis.

These benefits are very important for my users, as they help us and our customers secure our infrastructure from unauthorized access and detect spoofing, phishing, and all types of attacks, allowing us to identify vulnerabilities and patch them before exploitation.

What needs improvement?

There is not much to improve in Splunk Enterprise Security, but points such as deep learning and writing complex queries can be time-consuming, and managing multiple correlation rules can become complex over time, especially with high volumes of log data that can affect performance.

For how long have I used the solution?

I have been using Splunk Enterprise Security for almost three years.

What do I think about the stability of the solution?

Regarding stability, we have not faced significant challenges with Splunk Enterprise Security so far, though we have had some minor issues due to service failures, which were resolved without major threats. Its reliability is strong, especially after the visual redesign that helps prevent critical signals from getting lost.

What do I think about the scalability of the solution?

I rate the scalability of Splunk Enterprise Security as nine out of ten based on my use cases and observations.

How are customer service and support?

My experience communicating with technical support has been very good, as we quickly receive resolutions from them.

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

The AI-driven detections and assistance have improved the accuracy of my investigations.

Splunk Enterprise Security is very helpful in triaging and raising alerts before they reach SLA times, which helps us reduce the mean time to respond.

I estimate that we have reduced the mean time to resolve by around 40 to 70%.

Splunk Enterprise Security has helped reduce my team's average mean time to detect by around 50 to 70%, overall for threat detection and alert detection.

Regarding risk-based alerting, it helps us identify true positives and false positives, effectively eliminating alert fatigue; we rarely get false positive alerts, as RBA assigns a risk score to user devices and alerts analysts only when an asset accumulates enough risk score from different systems, exposing advanced persistent threats that traditional SIEM rules miss.

The threat topology or MITRE ATT&CK framework features help us easily identify unauthorized persons and attackers' tactics and techniques used to gain unauthorized access to our data center, making it easy to analyze active correlation rules and identify blind spots.

Splunk Enterprise Security helps us detect threats faster due to its advanced rule-based alerting and anomaly detection, allowing us to catch threats before they impact our services and servers.

I estimate that we can detect threats about 30 to 40% faster compared to traditional SIEM services.

How was the initial setup?

I participated in the initial setup of Splunk Enterprise Security, working with numerous device installations in Wazuh and Splunk Enterprise Security, including network devices, servers, and cloud services.

To set up Splunk Enterprise Security, we need to install Splunk Enterprise Security on the server, share logs with the forwarder, and then receive logs from the forwarder.

I faced some challenges specifically with the AWS integration during the initial setup.

Which other solutions did I evaluate?

I did not participate in the decision-making process for Splunk Enterprise Security, but I highly suggested it for small businesses seeking a low-cost solution.

I did not have any other options besides Splunk Enterprise Security.

What other advice do I have?

I consider Splunk Enterprise Security to be an affordable solution given the capabilities it offers; for organizations with predictable data environments wanting certainty in cost, it is a worthwhile investment. I rate this review as a nine out of ten overall.

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Centralized monitoring has improved threat detection and reduced response times significantly
Pros and Cons
  • "Splunk is one of the most powerful SIEM platforms due to its flexibility, scalability, and advanced search capabilities as it uses the SPL language."
  • "Regarding Splunk Enterprise Security improvements, I think there should be licensing flexibility, including cost optimization for larger data volumes."

What is our primary use case?

I work with a couple of security solutions as well as devices. We have companies such as IBM, Splunk, QRadar, and many other SIEM solutions. I have worked with technologies such as DLP firewalls, proxies, file transfer solutions, and monitoring via security monitoring solutions. I am from a security analyst background.

Regarding Splunk Enterprise Security, we have both this product and Splunk as a SIEM solution with us.

Regarding Splunk's real-time capabilities, I have been using it from the monitoring perspective. We have been onboarding our customers over to the Splunk platform, gathering log details from the security monitoring perspective, and building alerts over the Splunk platform. It serves as a SIEM solution and SIEM provider by Splunk. Splunk is one of the most powerful SIEM platforms due to its flexibility, scalability, and advanced search capabilities as it uses the SPL language.

Splunk has interactive dashboards with cloud detection and cloud integration platform capabilities, having their own built dashboards which help to get all details with the VPC flows and AWS data, showing how much data has been thrown, what the detections and vulnerabilities are, and we can easily access that information.

What is most valuable?

From our security monitoring perspective, the most valuable features are the dashboards. Splunk has a wide variety of dashboards and widgets available so I can monitor ROI, MTTD, and MTTR, which are required to adhere to SLAs with respect to clients. Splunk Enterprise Security also has valuable features such as the Splunk Processing Language (SPL), enabling analysts to perform advanced threat hunting, incident investigation, and log analysis over massive data sets for longer durations in real time. It helps create custom detections and rapid investigation queries.

Splunk Phantom with automation setup helped us reduce MTTD and MTTR time significantly. The automation ensures that detections get automated and notified to customers quickly. We have been positively impacted with the Splunk setup regarding automation and detection.

Splunk detects threats in real-time using the Splunk Query Language and helps with reduced MTTD and provides higher efficiencies. AI facilitates generating investigation queries without manual crafting. Interactive dashboards assist with retention, allowing analysts to prioritize alerts and start investigations quickly. The SOAR helps automate alerts and manage ITSM incidents, reducing MTTD and MTTR. UBA adds visibility to abnormal behaviors of users, and we have detected impossible travel incidents in near real-time and contained unauthorized attempts.

What needs improvement?

Regarding Splunk Enterprise Security improvements, I think there should be licensing flexibility, including cost optimization for larger data volumes. Additionally, for new users, the SPL language can be difficult. Practical examples provided within the dashboards or the query sets of datasets should be presented.

Regarding the pricing aspect, more licensing flexibility is needed. Splunk provides licensing based on data volume. If data peaks are above average, extra charges can occur. This should be optimal based on averages.

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 is stable. They have been pushing upgrades frequently, and this has remained stable as well.

How are customer service and support?

Splunk has continuously helped in terms of any issues or outages, helping us troubleshoot and having troubleshooting calls on a priority basis. They act according to their severity tags.

What was our ROI?

We have been having positive ROI. Time spent on log analysis and threat detection is less, and centralized multiple security tools have improved analyst efficiency. We have reduced our MTTD by about fifty percent with real-time detections.

What other advice do I have?

Splunk Enterprise Security has been helping us in terms of AI and detection quality. We have improved fine-tuning and reduced false positives. There have been no false positives in the environment, helping focus on true positives more.

Regarding risk-based volume, Splunk generates alerts based on risk and we focus on particular incidents. We have received positive feedback about RBAs helping with quick investigation and remediation. The Threat Topology helps with incident categorization and severity mapping. Minimal efforts bring content packs into production, requiring little fine-tuning.

I would rate this review a nine out of ten.

Risk-based alerting has improved threat visibility and reduced false positives for our analysts
Pros and Cons
  • "The features of Splunk Enterprise Security that I prefer the most are risk-based alerting, the new Mission Control, and the integrations that are coming into place between Mission Control and Splunk SOAR."
  • "Splunk Enterprise Security could be improved by having better role-based access controls."

What is our primary use case?

My main use cases for Splunk Enterprise Security are detections and incident response.

How has it helped my organization?

An example of how these features have benefited my organization is that risk-based alerting has transformed our ability to reduce the number of detections that we have, streamline our observability into risks and threats in our environment, and really focus our analysts on actual real problems, helping to remove the noise and false positives to a large degree. It frees us up to do actual work.

What is most valuable?

The features of Splunk Enterprise Security that I prefer the most are risk-based alerting, the new Mission Control, and the integrations that are coming into place between Mission Control and Splunk SOAR.

What needs improvement?

Splunk Enterprise Security could be improved by having better role-based access controls. We need to be able to better control who can do what, which people can be allowed to take certain actions, run certain playbooks, or view specific items, and separate things between teams.

For how long have I used the solution?

I have been using Splunk Enterprise Security for about 8 years.

How are customer service and support?

I evaluate customer service and technical support as fantastic. Technical support is some of the best that I've worked with.

I work with a lot of different vendors, and Splunk support is very responsive and capable. They have very knowledgeable people who can deep dive into the details and understand the inner workings of the platform without having to engage developers or back-end people all the time; they can just deal with it because they know what they're doing.

How would you rate customer service and support?

Positive

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

I have also used Google Chronicle and the Google SecOps platform. The factors that led me to consider a change included the lack of maturity in the other product and the maturity of Splunk. Google SecOps doesn't have anywhere near the capabilities of the Splunk ecosystem.

The search capabilities in Splunk Enterprise Security, and Splunk in general, are far superior to the search capabilities in Google's products. Their automation platform was extraordinarily immature. It doesn't have many of the basic capabilities that you would expect in an enterprise-class platform, and Splunk does have that. The Splunk capabilities were just vastly superior.

How was the initial setup?

I would describe my experience with deploying Splunk Enterprise Security as fairly straightforward.  We have detection engineers who know what they're doing, and so learning the detection platform in Splunk Enterprise Security was quick for them to pick up. Even those who were not familiar with Splunk Enterprise Security to begin with were able to pick that up quickly.

What was our ROI?

I have seen a return on investment with Splunk Enterprise Security.

What other advice do I have?

I would rate it an eight out of ten.

Which deployment model are you using for this solution?

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Risk-based alerting and custom dashboards transform communications and detect threats
Pros and Cons
  • "The stability and reliability of Splunk Enterprise Security is outstanding. It's a software and product that anybody can really pick up and use."
  • "Combating insider threats and advanced persistent threats is an amazing feature of Splunk Enterprise Security, and it gives us the visibility that we need for those detections that other software doesn't have."
  • "I'm not as familiar as I should be to answer how Splunk Enterprise Security can be improved, however, one of the improvement points that Enterprise Security could offer is on-prem training."
  • "One of the improvement points that Enterprise Security could offer is on-prem training, the availability to have a Splunk representative come out to different sites and actually sit down with the organizations and help them understand."

What is our primary use case?

Many of my use cases for Splunk Enterprise Security involve integrating with our networks and systems to troubleshoot and streamline our capabilities.

What is most valuable?

One of the features of Splunk Enterprise Security that I really enjoy is the ability to have the scalability of the product and the moldability that's really customized to meet our specific needs. 

The flexibility of Splunk Enterprise Security is beneficial, and that feature, while a broad statement, is crucial in itself, as it allows us to design our own environments with the flexibility and malleability needed to function effectively.

Splunk Enterprise Security's Risk-Based Alerting or RBA has been really amazing. We're still new at it, however, it's definitely nice to be able to have those results at your fingertips instead of having to search what you need to.

Using Splunk Enterprise Security's dashboards to communicate security posture to executives is probably one of the nicest things that Splunk offers. Not everyone is as skilled with the inner workings of the system as we are in my industry, so being able to put a visualization on there is critical.

The ability of Splunk Enterprise Security to ingest data has been amazing for our threat detection. Combating insider threats and advanced persistent threats is an amazing feature of Splunk Enterprise Security, and it gives us the visibility that we need for those detections that other software doesn't have.

The stability and reliability of Splunk Enterprise Security is outstanding. It's a software and product that anybody can really pick up and use.

What needs improvement?

I'm not as familiar as I should be to answer how Splunk Enterprise Security can be improved, however, one of the improvement points that Enterprise Security could offer is on-prem training, the availability to have a Splunk representative come out to different sites and actually sit down with the organizations and help them understand.

For how long have I used the solution?

I've been using Splunk Enterprise Security for about a year to a year and a half now.

How are customer service and support?

I handle most things in-house, however, I evaluate Splunk Enterprise Security's technical support and service as outstanding based on the few times we've had to contact them.

How would you rate customer service and support?

Positive

How was the initial setup?

My experience with deploying Splunk Enterprise Security is that the deployment process is pretty straightforward, especially once you have the certifications and you understand how the process works. I'd say it goes back to the training opportunities; some people are unfamiliar with it, so a little bit of support would be appreciated sometimes.

What was our ROI?

Splunk Enterprise Security has definitely reduced the amount of time that it takes us to detect and respond. I would say the percentage lowered by using Splunk Enterprise Security is around 25 to 30%.

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

I understand how the pricing, the setup costs, and the licensing of Splunk Enterprise Security work, however, I personally don't have knowledge of the numerical values.

What other advice do I have?

I'd give Splunk Enterprise Security a rating of ten out of ten. 

My advice to other companies considering Splunk Enterprise Security is to just do it. Don't look at any of the competitors; Splunk, hands down, is the product that I would recommend to other companies.

Unified event correlation and intelligence dashboards to strengthen business resilience
Pros and Cons
  • "I would assess the stability and reliability of Splunk Enterprise Security as good, as I have not had any issues with it."
  • "The most significant challenges I face when using Splunk Enterprise Security for advanced threat detection include not having enough time to be in it, the resources and people to also be in there, and trying to configure it and teach people how to use it. A lack of resources prevents us from giving it the attention it needs."

What is our primary use case?

My main use cases for Splunk Enterprise Security are event correlation and risk-based alerting.

What is most valuable?

The features I appreciate most about Splunk Enterprise Security are the different domains they have and the intelligence that comes along with each of those dashboards, being that single pane of glass for analysts to go in and look at. Splunk Enterprise Security has helped improve my organization's business resilience.

We use Cribl to pull data in and get it optimized before it hits Splunk Enterprise Security as far as collection. I have not done much customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security yet; we started off with just getting data in, and now we are at the point where we are starting to look at detections.

In Splunk Enterprise Security, I do not use risk-based alerting as much as we should. That goes back to the whole time issue, as we need to teach people what to do with it and how to tune them, and we do not have enough time in the day.

What needs improvement?

As for improvements to Splunk Enterprise Security, we will see how ES 8.2 looks. It is hard to say. We just found out about a bunch of changes, so it is difficult to make specific recommendations at this point.

The most significant challenges I face when using Splunk Enterprise Security for advanced threat detection include not having enough time to be in it, the resources and people to also be in there, and trying to configure it and teach people how to use it. A lack of resources prevents us from giving it the attention it needs.

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 would assess the stability and reliability of Splunk Enterprise Security as good, as I have not had any issues with it. I have experienced downtime, crashes, or performance issues with Splunk Enterprise Security only once or twice when we have had to restart our Splunk instance, and it has taken three minutes and come right back, so nothing major.

What do I think about the scalability of the solution?

Splunk Enterprise Security has not hit the point yet where we need to scale; we are still at the initial ingestion phase. We are in the process of expanding usage for Splunk Enterprise Security; we have not actually done it yet, as we are still planning and trying to get other teams involved while meeting their use cases, so we are probably a month away from that.

How are customer service and support?

I would evaluate customer service and technical support for Splunk Enterprise Security as far better than anything else, giving it an eight out of ten, thanks to the response times they meet. When going to our account representatives, if we need something, they are always responsive and we get whatever we need.

How would you rate customer service and support?

Positive

How was the initial setup?

The deployment was easy since we're cloud-based. We didn't really didn't have to do anything.

What was our ROI?

I have seen ROI with Splunk Enterprise Security. Just getting data in and being able to use the data and making sure it is compliant and mapping it to data models is far more efficient than any other SIM I have had experience with.

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

My experience with pricing, setup costs, and licensing for Splunk Enterprise Security is straightforward and self-explanatory. We are ingest-based, so we are not compute-based, making it pretty simple to get everything in without worrying about pricing.

Which other solutions did I evaluate?

Factors that led me to consider the change include shifting to a cloud-based solution at an affordable price and moving to something that is going to help reduce time spent on alerts and maintaining the system, with maintaining the system being probably the biggest reason since shifting to the cloud.

What other advice do I have?

For the future of Splunk Enterprise Security, I would want the Edge Processor to be able to send to multiple destinations rather than just Splunk, though that is more about Observability.

The advice I would give to other organizations considering Splunk Enterprise Security is that everybody wants to drive a Ferrari, so get the Ferrari of SIMs.

I rate Splunk Enterprise Security ten 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?

Correlation engine and alert features significantly reduce alert volume
Pros and Cons
  • "It's great for finding anonymous threats."
  • "The stability of Splunk Enterprise Security is very impressive; it is a very stable product."
  • "Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations. They are working on it, yet there are only five to ten very basic visualizations."

What is our primary use case?

The typical use case for Splunk Enterprise Security is to meet regulations and requirements for critical infrastructure. It is used to audit changes and authentication logs. The second purpose is for security operation center management and security management.

What is most valuable?

The most valuable features of Splunk Enterprise Security are the main component, which is the correlation engine that can specify detailed conditions such as how many events there need to be, what notification I will get, and if I get it per event or one per batch. 

There is also throttling; in basic Splunk, there is no throttling at all. In Splunk Enterprise Security, there is an additional layer of control of these alerts. I appreciate the correlations and the alerts in that product.

The asset management is particularly useful. We can enable asset lookups to show in every event. We define one, and it will translate to all events, allowing asset management to be easy. 

Splunk Enterprise Security helps to reduce alert volume because the language is similar to SQL with Google-style functionality above it. We can use these terms to specify what is in the allow list. We can specify what's in lookups, what should be there, and what's not. It definitely helps to reduce the numbers of full score.

Splunk Enterprise Security helps to speed up security investigations. When the finding is created, there are many correlations. You can quickly see what asset it is, what identity is involved, and you see the historical progress of what happened. Right from the findings, you can call VirusTotal and other resources, which is definitely helping.

I assess Splunk Enterprise Security's insider threat detection capabilities for helping to find unknown threats and anomalous user behavior as great. It regularly checks new events through the correlation search and compares them with threat intelligence. The threat intelligence is refreshed regularly, downloading new threat information. Splunk has a special research team for security content and intelligence, which distributes its own threat list to Splunk Enterprise Security.

It's great for finding anonymous threats. It checks new events and also works with the latest threat intelligence. At least once a day, it develops new threat information. In Splunk, there is a special research team. They are also distributing their own threat lists. The solution is capable of very good threat detection.

In basic SPL, with the Splunk query language, we can detect brute force without threats. It scans every event, and if it finds patterns, IOCs, it can trigger notable events, which are now called findings. The new version includes an internal Git repository, so when the SOC team makes improvements to the correlation search and makes changes, it automatically keeps a history of that correlation search, what was changed, when, by whom, and you can revert if it breaks.

The value that Splunk Enterprise Security offers in resilience is vital. It helps customers distributing gas across the Slovak Republic, ensuring that critical infrastructure, such as operational pipelines, are running. If there were an outage that delayed recovery, the economic impact could be significant. 

It's good for analyzing malicious activities and detecting breaches. The interface sometimes can be very essential.  

Splunk has helped us reduce alert volume. We can use terms to specify what is whitelisted and we can search like we would on Google. 

We've been able to speed up security investigations. We a finding is created, there are many correlations. You can quickly see the asset, the identity involved, the history, et cetera. 

What needs improvement?

Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations. They are working on it, yet there are only five to ten very basic visualizations. When you have your data all set and the customer wants some new dashboards that would help them, it is pretty complicated to build them from the built-in visualizations. 

This is one of the blocking points in Splunk, however, they're working on a new layer called Dashboard Studio. It is still limited. An older version of Splunk allowed implementation of JavaScript to capture events when a user clicked by mouse, which enabled great features. In the improved Dashboard Studio, this is not possible. They have improved one part and have made the other part worse, so it still lacks a premium feeling. Cisco will improve it, however, it seems they are focusing on what the big companies want. They will implement it if it's usable for these big players that pay, but for small companies, it's too pricey to use this solution.

For how long have I used the solution?

I've been working with this solution for seven years.

What do I think about the stability of the solution?

The stability of Splunk Enterprise Security is very impressive; it is a very stable product. They handle these things perfectly and conduct internal testing thoroughly. 

They test it very thoroughly before release, and our customers have Splunk running for months without issues. 

When I observe how customers work with Splunk in the cloud, it is also very good. They manage maintenance windows and inform customers, resulting in little to no interruptions to workflow. In terms of stability, I would give it a full score.

What do I think about the scalability of the solution?

We work with medium to large organizations. Our typical environment has 500 servers. In volume, we're looking at 100GB in storage. From Splunk's view, we're doing rather small volumes. It's big in a Central European context, and small from a Splunk North American context. It can be pricey for small companies. 

How are customer service and support?

I would rate technical support from Splunk Enterprise Security as a six out of ten. 

It's average, considering it's a very big product, and they handle several hundred tickets a day. I have opened 20 to 30 cases, and they helped me with only three to five of them. They try to close issues as soon as possible, often just offering documentation links. 

Even when I provide them with the core problem, they do not help much. The customer often has to rely on workarounds, custom scripts, and solutions which are somewhat lacking.

How would you rate customer service and support?

Neutral

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

Before Splunk Enterprise Security, I didn't use a different solution; this was my first job, and I started working full-time with Splunk about eight years ago. 

In the beginning, when they were testing, I was shown the OP5 and Nagios operating monitoring; we used tried them out, however, they were not really security-related.

How was the initial setup?

You can quickly set up Splunk by downloading the package, unpacking it, and starting to work. It's straightforward to get a quick view of your data, and you do not have to worry about connections to databases; it will start parsing the data as soon as you hand it over. For bigger environments with several hundred servers, Splunk Enterprise Security is the best solution.

What was our ROI?

Customers see the value in investing in this solution, particularly when it helps resolve issues quickly, turning a potential 20-hour response into one hour.

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

It's still pretty pricey. It's an expensive solution for smaller companies. 

That said, if someone evaluating SIEM solutions wants to go with the cheapest solution, Splunk Enterprise Security is a very good option. It has difficulties in administration and setup, however, in comparison with other products, it's still a great platform.

What other advice do I have?

My relationship with Splunk is that we are a partner and reseller partner. My organization does not monitor multiple cloud environments; we primarily monitor M365 and Azure environments from cloud products. We use the Microsoft Add-on for Splunk to read Exchange and Microsoft audit logs from the cloud. However, we still prefer on-premise solutions in our country.

We use the Mission Control feature. It's replaced another component. I don't use it too much myself. It's like a connector for SOAR. We're investigating its capabilities and have not implemented it fully.

Overall, I would rate Splunk Enterprise Security a nine out of ten. If you want to see your data quickly and in full view, it's very good - specifically for bigger environments.
