I mostly use the solution in my company for incident response, ticket management, and integration with other endpoint products.
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?
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.

April 2026
Learn what your peers think about Splunk Enterprise Security. Get advice and tips from experienced pros sharing their opinions. Updated: April 2026.
894,738 professionals have used our research since 2012.
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.
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)
Disclosure: My company has a business relationship with this vendor other than being a customer. End user
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.

Security Engineer at Softtek
Has been instrumental in improving our incident response time, especially for user authentication issues
Pros and Cons
- "Splunk stands out for its extensive application integrations."
- "The user interface is not user-friendly for non-technical users."
What is our primary use case?
Splunk Enterprise Security offers a wide range of capabilities that benefit our organization. This includes user behavior analytics, which helps us identify suspicious activity. Additionally, Splunk Enterprise Security allows us to create custom alerts for various internal security needs.
How has it helped my organization?
Splunk has been instrumental in improving our incident response time, especially for user authentication issues. It excels at detecting anomalous behavior, such as brute force attacks or multiple login attempts from a single source. This allows us to quickly identify and address potential security threats, making Splunk a vital tool for our cybersecurity incident response efforts.
The asset and identity management feature strengthens our overall security posture. This system relies on the creation of security roles by administrators. These roles then determine access permissions based on the principle of Role-Based Access Control. In this way, access is carefully controlled and assigned based on specific job duties. It's important to note that administrators retain a high level of access and make final decisions regarding access permissions.
Splunk offers a variety of dashboards, including real-time dashboards that update continuously. These dashboards complement Splunk's real-time alerts by providing a visual overview of our system's health. They can be built to leverage different Splunk resources, like indexes, search clusters, and host clusters. This allows us to monitor key metrics and identify potential issues in real-time, helping us maintain a healthy and efficient system.
Our SoC and Analytics teams use Splunk to monitor multiple cloud environments.
The visibility into multiple environments is good.
The insider threat detection is valuable for our organization because it helps us identify unknown threats. While we leverage existing threat intelligence for known threats through signatures and endpoint protection tools, these methods have limitations. Since they rely on predefined information, they can't be readily integrated with Splunk to monitor for and generate alerts based on these known threats. Splunk's strength lies in its ability to detect anomalies and suspicious user behavior, which can be crucial for uncovering insider threats that might bypass traditional signature-based defenses.
Splunk Enterprise Security excels at analyzing malicious activity. Our team has created several use cases to identify such activity. These use cases focus on data patterns that might indicate malicious intent, such as a sudden increase in login attempts or logins occurring outside of regular business hours. Additionally, we can identify brute force attacks attempting to crack passwords through repeated login attempts. This allows us to effectively monitor for and respond to potential security threats.
It has improved our detection ability and has helped reduce our alert volume to a manageable level.
Splunk has helped speed up our security investigation.
What is most valuable?
Splunk stands out for its extensive application integrations. It boasts a user-friendly interface with intuitive features that are easy to understand and navigate for technical users. This accessibility is a major reason why I find Splunk so appealing.

For how long have I used the solution?
I have been using Splunk Enterprise Security for three and a half years.
What do I think about the stability of the solution?
Splunk Enterprise Security is extremely stable.
What do I think about the scalability of the solution?
Splunk Enterprise Security is easily scalable.
How are customer service and support?
We have only had minimal contact with Splunk technical support.
How would you rate customer service and support?
Neutral
How was the initial setup?
The initial deployment is straightforward.
What's my experience with pricing, setup cost, and licensing?
Splunk Enterprise Security is affordable.
While affordability is important, I recommend Splunk Enterprise Security over the cheapest option on the market. This is because Splunk offers a robust feature set that justifies its cost.
What other advice do I have?
I would rate Splunk Enterprise Security nine out of ten.
We have Splunk Enterprise Security deployed across multiple locations.
Splunk Enterprise Security requires minimal maintenance.
I recommend Splunk Enterprise Security as a scalable and reliable solution for both on-premises and cloud environments.

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?

Pros and Cons
- "Splunk Enterprise Security is a very useful application to collect all the logs and also to find out the problems. You can easily create whatever you want by using its features, and it also has the capability to collect from all kinds of different platforms. Splunk Enterprise Security provides me with all the alerts."
- "Splunk Enterprise Security is a very useful application to collect all the logs and also to find out the problems."
- "I didn't face any major issues with Splunk Enterprise Security. There were only one or two issues related to the user account, but nothing major."
- "There were only one or two issues related to the user account, but nothing major."
What is our primary use case?
My main use case for Splunk Enterprise Security is centered around threat detection and incident response. I’ve configured correlation rules and alerts within the SIEM to proactively detect suspicious activities. The environment includes multiple servers and security devices from which I collect log data using forwarders. These logs are ingested into Splunk, parsed, and analyzed to identify anomalies, security issues, and performance concerns. This setup helps streamline investigations and reduce response time to potential threats.
How has it helped my organization?
Splunk Enterprise Security has significantly improved our organization by centralizing log management, enhancing visibility into security events, and enabling faster detection and response to threats. The customizable dashboards, real-time alerts, and powerful correlation capabilities have streamlined our incident response process and reduced investigation time. It has also helped us meet compliance requirements more efficiently by automating reporting and audit trails.
What is most valuable?
Splunk Enterprise Security’s most valuable features include its powerful log aggregation from diverse platforms, flexible search and correlation capabilities, and customizable alerting system. It allows me to collect logs from virtually any source—servers, firewalls, cloud services—and create custom rules to generate meaningful alerts. The flexibility of Splunk’s Search Processing Language (SPL) makes it easy to build tailored dashboards, identify threats, and quickly pinpoint the root cause of issues, significantly improving operational efficiency and threat detection accuracy.
What needs improvement?
While Splunk Enterprise Security works well overall, improvements could be made in user management—particularly around simplifying role-based access controls and troubleshooting user account issues. Additionally, future releases could benefit from:
Improved UI/UX: A more intuitive interface for new users and simplified dashboard customization.
Built-in Use Case Library: More out-of-the-box security use cases and alert templates to reduce setup time.
Cost Optimization Tools: Better native tools to monitor and manage licensing usage and storage costs.
Enhanced Cloud Integration: Streamlined and more secure integration with major cloud providers for hybrid environments.
These enhancements would make the platform even more user-friendly and efficient.
For how long have I used the solution?
I have been working with Splunk Enterprise Security for about two years.
Which solution did I use previously and why did I switch?
I previously used Dynatrace and open-source tools like SigNoz. While Dynatrace excels in application performance monitoring, it requires an additional license fee for server-side log collection, making it less ideal for centralized log management and SIEM use cases. SigNoz, being open-source, offers basic log management but lacks the depth, scalability, and advanced threat detection features of Splunk Enterprise Security. I switched to Splunk Enterprise Security because it provides a comprehensive, all-in-one solution for security monitoring, log aggregation, and real-time alerting, which better fits enterprise-level security needs.
How was the initial setup?
The initial setup of Splunk Enterprise Security was straightforward. I followed publicly available documentation, which was clear and easy to understand. The installation and configuration process went smoothly without any major issues. From initial setup to full deployment—including log collection, rule configuration, and dashboard setup—everything was completed in about two days, demonstrating how well-documented and accessible the deployment process is for users with a solid technical background.
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?
On-premises

Associate at PricewaterhouseCoopers
Provides centralized monitoring, customized dashboards, and speeds up security investigations
Pros and Cons
- "The most valuable features in Splunk Enterprise Security are the cluster capabilities."
- "The licensing price is high and has room for improvement."
What is our primary use case?
I'm part of the Splunk operations team, which means I support Splunk functionality and occasionally conduct threat management onboarding. We assist various teams with threat-related tasks. If they need help bringing log sources into Splunk, we guide them through the process. Once the logs are onboarded, we create correlations to identify threats, troubleshoot issues, and help mitigate potential risks.
How has it helped my organization?
We handle incidents through a queue configured in our event management system. This includes automated incidents for our Splunk infrastructure, like server health checks, and user-reported issues where functionalities like the fetch score aren't working. We address all incidents, whether automated or user-raised, through this system.
We've made significant improvements to our Splunk infrastructure to support our internal teams. This ongoing effort focuses on helping application teams onboard logs from various applications for their review and troubleshooting. We've streamlined the onboarding process, improved data quality, and ensured smooth data consumption for our internal users.
Splunk Enterprise Security offers multi-cloud environment monitoring capabilities that we can utilize for our users if they require it.
We can build a dashboard in Splunk to centralize the monitoring of critical information. This dashboard can display key metrics for onboarding methods and LogSources we actively track, providing a clear view of our entire monitoring environment.
While Splunk Enterprise Security offers good threat detection capabilities, our current process limits visibility into user activity. When users request correlations, we create the code and configure everything on our end, and then they test and work on it from theirs. This lack of transparency extends to threat management, as we can't directly see tickets in their separate ServiceNow system. If they encounter issues, they share details in a document for us to review and address.
It comes with a large collection of correlation searches, but we'll need to review them to find the ones that match our specific needs for monitoring malicious activity. Once we've identified the relevant searches, we can customize or recreate them within the correlation settings to best suit our environment.
Splunk Enterprise Security helps us detect threats faster.
Splunk Enterprise Security is a good monitoring tool that allows us to track specific details by creating custom queries. For instance, to monitor a particular organization's infrastructure, we would first onboard their logs and then create queries to capture relevant information. This way, any suspicious activity, attacks, or other events would be easily identified within the infrastructure. Additionally, Splunk's checkup operation minimizes the chance of missed alerts by automatically identifying detections, ensuring near-complete coverage of around 99 percent unless there are outages or limitations with global agents.
Splunk Enterprise Security helps us speed up our security investigations.
The customizable dashboard for our security operations is a good feature.
What is most valuable?
The most valuable features in Splunk Enterprise Security are the cluster capabilities.
What needs improvement?
The licensing price is high and has room for improvement.
For how long have I used the solution?
I have been using Splunk Enterprise Security for four years.
What do I think about the stability of the solution?
Splunk Enterprise Security is stable.
What do I think about the scalability of the solution?
Splunk Enterprise Security can scale according to our needs.
How are customer service and support?
The technical support has been successful in resolving the majority of our cases.
How would you rate customer service and support?
Positive
How was the initial setup?
While the deployment process itself is simple, the number of personnel needed varies depending on the infrastructure size and user base. A small deployment for 50 users can be completed by two people, while larger deployments supporting over 500 users may require up to 15 people.
What's my experience with pricing, setup cost, and licensing?
The Splunk Enterprise Security license is expensive.
What other advice do I have?
I would rate Splunk Enterprise Security eight out of ten. Splunk improves user efficiency by streamlining workflows and enabling the detection of anomalies within data.
Splunk Enterprise Security is deployed across multiple locations in our organization.
To ensure our data remains secure, Splunk servers require monthly maintenance. This maintenance includes installing security patches that address vulnerabilities and prevent unauthorized access to our information.

The user interface gives you a single dashboard to directly view all high-level information
Pros and Cons
- "I like Splunk's automated threat detection and orchestration capabilities. Splunk offers a single solution for analyzing, aggregating, correlating, monitoring, reporting, visualizing, etc. You can get all of these capabilities in one place. On top of that, it provides a cloud, testing, on-premise, and hybrid solution, giving customers more flexibility for their use cases."
- "We've sometimes faced issues with upgrades. The incident review dashboard sometimes breaks after updates. When we add a space or something in the description or anywhere in the SQL, the drill-down value may be reset with a blank value. Before rolling out any software, they should test it thoroughly and ensure clients won't have issues with the upgraded version. It should be compatible with all or most of the apps. All major issues must be addressed before rolling out the upgrade."
What is our primary use case?
I use Splunk for visualization, reporting, monitoring, log aggregation, and other security purposes. We gather various logs into one place and analyze them based on specific business use cases to get high-level insights that inform decision-making at every level of the organization. We also use it to aggregate other IT logs — not just security.
Our organization is working in a massive on-prem environment. We're one of Splunk's oldest clients. It's convenient to migrate everything to the cloud, and we would have more flexibility. However, we currently have our resources and everything established to use Splunk on-premises, so we aren't switching to a cloud environment.
How has it helped my organization?
Splunk allows us to monitor logs and track suspicious activity in real time. With the help of the SOAR platform powered by AI and ML, we can respond quickly. Our security posture is better, and we can resolve security incidents quicker. Splunk has improved our visibility by providing critical security metrics in our dashboard and strengthened our security controls.
The number of alerts we receive is similar to what we saw using our previous solution. While it hasn't necessarily reduced our alerts, Splunk is improving our resolution time and overall security.
What is most valuable?
I like Splunk's automated threat detection and orchestration capabilities. Splunk offers a single solution for analyzing, aggregating, correlating, monitoring, reporting, visualizing, etc. You can get all of these capabilities in one place. On top of that, it provides a cloud, testing, on-premise, and hybrid solution, giving customers more flexibility for their use cases.
Splunk's real-time monitoring is one of its best features. The user interface gives you a single dashboard to directly view all the high-level information. The security incident monitoring and investigation page is also very helpful. You can document an investigation step by step. Many investigators can work on a single incident also based on their shifts. Everyone can add notes on the investigation page.
The incident response features are based on real-time data. The monitoring team can immediately take over an incident and prioritize tasks based on risk scores. We can assign multiple technicians to one security incident based on their skill, improving resolution time. The incident review dashboard provides many useful details, like the indicators of compromise and risk scores.
We can get threat intelligence from multiple platforms, including the latest known IOCs, to support our response to security incidents. We store the threat data from various sources in a centralized place, and it updates every six to 12 hours.
The MITRE ATT&CK framework feature is helpful for understanding which phase an incident is in and what the next steps are so a technician can prevent it from progressing. It gives us a detailed overview of other tactics it might be associated with, enabling us to stay vigilant. We can correlate with other simultaneous or sequential incidents and take action to strengthen our security based on these incidents.
What needs improvement?
We've sometimes faced issues with upgrades. The incident review dashboard sometimes breaks after updates. When we add a space or something in the description or anywhere in the SQL, the drill-down value may be reset with a blank value. Before rolling out any software, they should test it thoroughly and ensure clients won't have issues with the upgraded version. It should be compatible with all or most of the apps. All major issues must be addressed before rolling out the upgrade.
For how long have I used the solution?
I have used Splunk for eight or nine years.
What do I think about the stability of the solution?
I rate Splunk nine out of 10 for stability.
What do I think about the scalability of the solution?
I rate Splunk eight out of 10 for scalability. Scalability is always a challenge. The larger your environment, the more issues you'll have. There aren't many problems with Splunk on the cloud, but scaling can be challenging in an on-prem environment. If you're ingesting a significant volume of data, you need a proper maintenance routine to maintain your base architecture. Sometimes, it's a bucket application. It can take a few hours to reset those things, and network issues might contribute to that.
How are customer service and support?
I rate Splunk support eight out of 10. It varies based on your data volume and number of licenses.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I have used several solutions for different clients, including QRadar, Palantir, and Microsoft Sentinel. Splunk has more capabilities than QRadar. It's also more flexible and user-friendly. You can modify and customize the solution to show you the information you want.
How was the initial setup?
The deployment depends on the environment. It may take only a couple of weeks to deploy Splunk in a small environment, but a larger environment involves a detailed process that may take months. It helps to have a larger staff. It also depends on how process-oriented an organization is. Some organizations will take much more time in the planning and design phase.
After deployment, Splunk requires a good deal of maintenance, depending on the volume of data you're ingesting and your user base. It may require multiple resources to manage this environment.
What was our ROI?
Splunk improves our security controls, resolution time, and threat-handling capabilities. We're saving time and resources, meaning more money for our clients.
What's my experience with pricing, setup cost, and licensing?
I don't know about Splunk's pricing because I work on the technical side, but I know it is a costly platform. There are cheaper products and some open-source ones, but Splunk costs a lot because of the features it provides. Still, the pricing is a concern for many of my clients, and more would use Splunk if they lowered the cost a bit.
What other advice do I have?
I rate Splunk Enterprise Security nine out of 10. I would recommend Splunk because it covers multiple services in one place. It also has a strong developer community. You can easily get help from community support. Splunk is a versatile product that competes well with leading security tools like Microsoft Sentinel.

Early incident detection has saved the company from financial losses
Pros and Cons
- "Incident detection is the positive impact I have seen from Splunk Enterprise Security; it probably saved the company from financial losses because of the early detection of the incidents."
What is our primary use case?
For incident detection, this is the main purpose for which I can use the product. That is the only use case for my team. It may be different for my team who is actually processing the incidents and a bit different for me, as I am a manager. For me, the most important aspect is making statistics over a period, seeing who did what, and extracting all the needed information. It is quite easy and intuitive.
What is most valuable?
Incident detection is the positive impact I have seen from Splunk Enterprise Security. It probably saved the company from financial losses because of the early detection of the incidents. I cannot say about ROI because I am not involved in financial matters, so I cannot estimate any kind of cost.
What needs improvement?
There are so many products and features that it may be quite hard sometimes to find something that you are looking for. Search capabilities or maybe some kind of AI assistant helping to find what you want would be beneficial improvements.
For how long have I used the solution?
I have been dealing with the product for about seven years.
What do I think about the stability of the solution?
From time to time, there are some glitches with stability. Some logs are missing, and we have an external SOC team handling this license for us. Whenever there is something wrong with Splunk Enterprise Security, they need to raise a ticket, and it can be time-consuming to wait for them to reply; this is also a disadvantage.
What do I think about the scalability of the solution?
It is easy to scale up or down if you have the money. The solution is quite pricey not only because of the license but also when scaling it and maintaining it.
How are customer service and support?
I have not raised any ticket myself, but I have heard some not very good stories about technical support from Splunk Enterprise Security. Support did not provide quick enough help.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I have not been using any other competitors.
How was the initial setup?
I have no idea about installation because I took no part in it.
What about the implementation team?
We have a dedicated team that is doing all the configuration of Splunk Enterprise Security for us. We are just managing what has been prepared for us.
What was our ROI?
It saved the company from financial losses because of the early detection of the incidents. I cannot say about ROI because I am not involved in financial matters, so I cannot estimate any kind of cost.
What's my experience with pricing, setup cost, and licensing?
I heard the solution is quite pricey.
Which other solutions did I evaluate?
I have not been using any other competitors.
What other advice do I have?
Users should know what they are looking for. Splunk Enterprise Security is probably customizable enough that they could achieve their goals, but they need to know what they want to get from it. On a scale of 1-10, I would rate Splunk Enterprise Security an eight 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?
Other
