At a high level, its use cases are related to security monitoring, log aggregation, and a little bit of analysis related to incidents or fraud.
Cyber Security at a financial services firm with 5,001-10,000 employees
Integrates well, provides good visibility, and helps to identify things that can lead to a larger problem
Pros and Cons
- "Integration with the cloud is pretty important and good for us. We found the integration with a lot of tools, not all tools yet, valuable. It does make the transfer of data, log files, and other things easier for us."
- "Its pricing is extremely high. There are other tools out in the market that are competitive. They do not necessarily have all the functionality, but they are competitive. The professional services we have used have been high as well in comparison to the market."
What is our primary use case?
How has it helped my organization?
Splunk Enterprise Security has created better visibility for us on the cybersecurity type of events and issues. We are still maturing, but where we have seen some growth is getting better data, knowing what data to look at, and how to understand that data.
It has end-to-end visibility into our cloud-native environment. This is extremely important for us because of the type of business we do. We have a lot of PII data and a lot of compliance data on which we have to maintain very tight controls, so it is extremely important that we are able to put that in the cloud and monitor and watch our environment very closely.
It has reduced our mean time to resolve, but we are still maturing. We have got a lot of maturing to do. We have got a lot of growing to do. We have also been limited on the staff to be able to get the full realization of what we can get out of it yet, so that is a place where we are continuing to grow.
It has improved our business resilience. We have been able to identify things that could have presented a larger problem for us financially or legally through various events. We have been able to leverage the data there. We have been able to maintain that data and support that data. It does the job. It meets the needs.
Splunk has not helped to predict problems in real time because we have not yet matured to that place, but we need to. Generally, it has been helpful, but we know that we have got a lot of growing up there. We still have not got everything identified and captured in the space we want to be able to do better analysis.
Its ability to provide business resilience by empowering our staff is really high. Empowerment is great, but we have a resource problem, so we have not quite realized where we could be.
We monitor multi-cloud environments. We have three of them. It is difficult to monitor them currently with Splunk. We are living in a highly regulated stack and a very little regulated stack and the ability to get a single pane of glass for all of that is very difficult.
What is most valuable?
Integration with the cloud is pretty important and good for us. We found the integration with a lot of tools, not all tools yet, valuable. It does make the transfer of data, log files, and other things easier for us.
What needs improvement?
Its pricing is extremely high. There are other tools out in the market that are competitive. They do not necessarily have all the functionality, but they are competitive. The professional services we have used have been high as well in comparison to the market.
In terms of scalability, it is hard to forecast where you are going. There is room to improve there.

849,963 professionals have used our research since 2012.
For how long have I used the solution?
I have been using this solution for about five or six years.
What do I think about the stability of the solution?
I would rate it eight out of ten in terms of stability. Where there has been ambiguity for me is that I recently had system stability issues that were beyond my control. They were part of my solution, and I was not aware that Splunk was accountable for it. It got quickly resolved, but there was a gap there that created pain for my business.
What do I think about the scalability of the solution?
We have not had any issues. We also have not had any detriment, but it is hard to forecast based on where you are going from a business perspective, at least with the models and the account teams that I have been working with. There is room to improve there.
How are customer service and support?
It has been a rocky road. I have been through a road where I have had limited to little engagement or support. I am on the cusp of a large turnaround, meeting with my client team and dialoguing through it. Based on the history, I would probably rate their sales support a four out of ten. Going forward, I would rate their sales support an eight out of ten. They are in the right direction. I would rate their technical support a nine out of ten.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We have been using the same solution for five or six years. It was selected before I joined, so I do not know.
How was the initial setup?
I joined after it was implemented. What I am working on now is the technical depth. I am spending a lot of time with the teams there for direction strategy. Splunk has done a great job there, specifically in pulling the right resources to bear. I had executive briefings directly with executives today where we had an opportunity to talk about different components of our solutions and our stacks, and it has been very good.
What was our ROI?
We are in a growth state right now. We have seen an ROI, but anticipating any point in the future is a little difficult, so it is a mixed response. Our scale is not quite clearly defined to be able to put it to a metric or to tie it back to consumption use. There is a little bit of autonomy in there to over-adjust and still find that we can true-up in a better space. That has been good for us, but if you let that run away from you, then you start to get in trouble.
We have not seen any cost-efficiency. We have seen our usage and needs grow, so we have seen Splunk go up in cost for us. We have not quite realized any efficiencies yet. It is also indicative of our maturity model.
What's my experience with pricing, setup cost, and licensing?
The licensing is good, but the pricing absolutely needs some work. It is very high. One thing that they put in a contract, but they do not emphasize it enough is true-ups on usage based on the quarterly consumption. They do not follow that methodology. They let a customer use, use, and use, and then at some point, a true-up occurs, and it is a large cost. There is an opportunity to do a quarterly track type of true-ups as per the agreements out there. That would put them in a position where customers are able to plan on, forecast around, and work through volume adjustments that may occur in their environment.
The other place where Splunk could spend time is the scale-up and scale-down model. Scale-up is easy where you get more business, and it is easy to add more capacity, whether it is storage or SVUs, but when you need to scale down because of a change in a business, it does put customers in a position where they are locked in, and there is no way to maneuver around that.
Which other solutions did I evaluate?
We do an evaluation annually. It is important for us to do a market comparison and make sure we are looking at options in our work. What makes Splunk Enterprise Security competitive is the variabilities that they bring to the table for the overall solution. It has things like APIs that you can tie into. There is also the bonus functionality of being able to do analytics there. User behavior analytics is important for us.
What other advice do I have?
I would rate Splunk Enterprise Security an eight out of ten.
Disclosure: I am a real user, and this review is based on my own experience and opinions.

SOC Analyst at a tech services company with 10,001+ employees
Helps us to plan, know where to look, and what to look for when we have an incident
Pros and Cons
- "I haven't had the chance to properly sink my teeth into Enterprise Security but so far I like that they added the MITRE ATT&CK features."
- "The training was mostly sales-focused, like how to monitor your sales. It was hard to then come back from doing the training and try to switch it to a cybersecurity focus because all the training we did was sales oriented. The basic training didn't really touch on any kind of cybersecurity use cases or anything like that. That would have been great to see in the training."
What is our primary use case?
Our primary use case is for cyber security, tracking logs, and incident response.
What is most valuable?
I haven't had the chance to properly sink my teeth into Enterprise Security but so far I like that they added the MITRE ATT&CK features.
This feature helps us know how to plan when we have an incident, know where to look, what to look for, and aspects like that.
The MITRE ATT&CK planning is valuable. When we see those incidents and those logs, having the information right there speeds up the process a bit.
We did not have a SIEM at the time, so we added Enterprise Security as our SIEM. We're hoping to learn more about it and grow as we progress.
What needs improvement?
They wanted us to do basic training, which was offered to our organization for free. That was great. However, ours is a cybersecurity focus. The training was mostly sales-focused, like how to monitor your sales. It was hard to then come back from doing the training and try to switch it to a cybersecurity focus because all the training we did was sales oriented. The basic training didn't really touch on any kind of cybersecurity use cases or anything like that. That would have been great to see in the training.
For how long have I used the solution?
We upgraded to Enterprise Security a year ago but have been using general Splunk for longer.
What do I think about the stability of the solution?
Stability-wise, despite these issues, it's been solid. I haven't had any issues with access to it or anything like that. The only issue we did have was with the engineer. After informing him of those issues, he went back and tweaked them, and then everything worked fine.
What do I think about the scalability of the solution?
It seems pretty scalable. Our network isn't extremely large, so I don't think scalability will be an issue in our case, but I definitely see the opportunity to scale if needed.
We have around 8,000 devices, so it's a fairly small network. It's across several different networks.
How are customer service and support?
I have not used support yet mainly because I haven't delved into it as much because of the issues with our initial integration with our engineer not being so trained.
Which solution did I use previously and why did I switch?
We have different contractors and they have other solutions. Some of those solutions included Elastic. We want to use Splunk and our contractors want to use Elastic. We're hoping .conf23 will broaden our imagination, so we'll have more to bring back and push towards just using Splunk only.
I have not used Elastic myself. It does sound like it does a lot. There's a lot that Splunk offers that we haven't actually used. I want to play with Mission Control. We only use Enterprise Security but I do want Mission Control where everything is in one centralized application where you don't have to jump to different applications.
I would love to get Mission Control.
How was the initial setup?
My engineer had a little bit of an issue with it but it was because of his own lack of training. We were pushed to hurry up and get a SIEM. He did the best he could. I let him know what wasn't working, and then he would try to fix what he could on the backend so it could work. He was in talks with Splunk to fix those issues. The results are coming back a bit better, but I think that there is still room for improvement.
I was not involved with the setup. I came in afterward. One of our guys here was the one that was in the initial integration of Splunk. We ended up with Splunk as our main SIEM. I've never had any issues with it and I enjoyed it.
What was our ROI?
We will see cost efficiencies mainly just from saving time and the shortened time and response to those incidents that we see. The fact that everything's organized in one application, we should see a bit of an increase in efficiency.
What other advice do I have?
I do see the possibility and the opportunity to increase the meantime to resolution by a lot. We use several different applications to monitor logs. We have the vision.
I've seen some of the updates and changes like Splunk AI and Splunk Vision Control that look nice. I didn't manage to get on some of the hands-on, which would have been lovely. I would like to get more ideas on how we can integrate Splunk into our networks.
I would rate Splunk Enterprise Security a nine out of ten. I see the opportunity and I'm hoping with our engineer that we can get to where we can make the best use of Splunk. It really seems great. A lot of our staff here were all ready to use it. We're just hoping our engineer can get to the place where we can actually make use of it.
The biggest value I get from attending a Splunk conference is being able to see the updates, changes, the features they're adding, the Splunk AI, and Splunk Vision Control. That's been nice. I am looking forward to some of the sessions. I want to get more ideas on how we can integrate Splunk into our networks and things like that, especially focusing on cybersecurity. I would also like to see some of the stock sessions because it's a brand new stock. We're trying to stand it up. Seeing how they're using it for stocks would be great.
Which deployment model are you using for this solution?
On-premises

Security Compliance Program Manager at a educational organization with 5,001-10,000 employees
Incorporates a lot of elements that help to reduce security risks but the architecture isn't well-defined
Pros and Cons
- "Splunk incorporates a lot of elements that help to reduce security risks. For it to reach certain compliance, we need to have some security insight. Splunk is a very good SIEM, it’s a top solution, but the best feature is its cost of visibility. We have all the most important features to detect vulnerabilities or risks."
- "I have concerns about the architecture as well since I can see it is not very well defined."
What is our primary use case?
Splunk helps us to be proactive and it integrates with many devices. It offers visibility from many different levels, areas, zones, and devices rather than from a single system. We can use this intelligence to create correlations, system solutions, etc. Splunk reduces the risk factors and helps us in many ways beyond just collecting logs. Though Splunk is costly, it has many features like threat intelligence which is very useful. It helps us be proactive about reducing risks.
What is most valuable?
Splunk incorporates a lot of elements that help to reduce security risks. For it to reach certain compliance, we need to have some security insight. Splunk is a very good SIEM, it’s a top solution, but the best feature is its cost of visibility. We have all the most important features to detect vulnerabilities or risks.
What needs improvement?
Customers cannot manage or maintain the servers on the cloud since they are all deployed. Since there are platforms, they can become a little bit hectic. One of my other observations is that the applications that are available on the store are not updated as much as those available on on-prem.
Moreover, I have had issues with the Splunk store. I believe that the developers in the Splunk store are external and I can see that the level of maturity of these developers ranges between low and medium. I have never seen the maturity go up higher. The applications are not maintained regularly and it can cause issues in the visibility dashboard. I would suggest to Splunk's tech team to keep the store private, so that Splunk creates its own applications without the interference of external developers.
I have concerns about the architecture as well since I can see it is not very well defined. However, this is not the case with on-prem. We were able to manage and do whatever we wanted on the server level without opening a case or anything else. Moreover, the applications are updated every six months.
What do I think about the stability of the solution?
Splunk is a stable solution.
What do I think about the scalability of the solution?
Splunk is a scalable solution. I am also impressed with the integrity of the solution. It is very good at collecting logs.
How are customer service and support?
To resolve issues in the Splunk platform, you need to wait in a queue and then open a ticket with the support team. I find it a bit time-consuming since it takes time to call tech support and get what you need.
Which solution did I use previously and why did I switch?
I have used Wazuh. From my point of view, Wazuh is a simple and basic SIEM solution compared to Splunk in terms of features. I don’t see Wazuh as a competitor to Splunk. Wazuh relies greatly on human tactics. It is best suited for cloud environments and maybe smaller ones. I have issues with Wazuh’s stability as well because I have found scenarios where it was working for one instance and not for another. These issues might be because it is open-source.
Wazuh is not actively working on their platform. I opine that they need to integrate many components and have many aspects automated so that the solution does not depend on its users. I have found issues with the language of Wazuh as well. It requires a lot of resources and time to learn the language. These issues make me think that Splunk is better than Wazuh.
How was the initial setup?
The initial setup process for Splunk was simple. The language used in Splunk is very easy to pick up and you can rely on any person using it to be able to learn it quickly. The language and picking up logs are easier with Splunk.
What about the implementation team?
I implemented Splunk through a POC.
What's my experience with pricing, setup cost, and licensing?
Splunk is costly but it’s worth it due to the high-end features.
Which other solutions did I evaluate?
I have worked with Wazuh and ManageEngine Endpoint Central.
What other advice do I have?
I would rate Splunk Cloud a 6.5 out of 10, but plugged on time, I would give it 8.8 out of 10. The maintenance of Splunk is a bit difficult due to the time-consuming tech support.
I would recommend Splunk. I cannot compare Splunk with any other SIEM solution because I have worked with many different solutions and logarithms, like the ManageEngine Endpoint Central, and Wazuh. I have used Splunk for two years and I can see Splunk as really the best SIEM solution that can be used for work. I totally recommend it even though I gave some negative feedback, it's because I am coming from a product perspective. We have to also take into consideration the security perspective. I am not talking about only visibility in which they should take a lot of care, but the way the solution is handling and even manipulating the data. This is the most valuable thing.
Which deployment model are you using for this solution?
Private Cloud

CTO at IHS Markit
We were able to create a catalog of dashboards and have a holistic view at all levels, understanding our business better
Pros and Cons
- "The dashboards are the most valuable feature. We like the ability to drill in and see what queries are under the dashboard, build new visualizations, edit the querying, and see the reports."
- "We were able to create a catalog of dashboards and have a holistic view at all levels. We could understand our business much better. Real-time errors, which were buried in emails before now, surfaced up on dashboards."
- "We do have to educate developers on how to not blow it up. It is a little to easy to write an expensive query and overly stress the system. This could be improved."
- "I would like additional features in different programming models with the support for writing queries in SQL or other languages, such as C#, Java, or some other type of query definitions."
What is our primary use case?
We use it for logging and troubleshooting.
How has it helped my organization?
Every team immediately created their own Splunk dashboard, and all the product owners were ecstatic about this. We were able to create a catalog of dashboards and have a holistic view at all levels. We could understand our business much better. Real-time errors, which were buried in emails before now, surfaced up on dashboards. Even our executives could understand this, and it changed the way teams thought about alerting and reporting. It allowed us to send out real-time notifications to integrate with Opsgenie, and it changed the way IT works.
What is most valuable?
The dashboards are the most valuable feature. We like the ability to drill in and see what queries are under the dashboard, build new visualizations, edit the querying, and see the reports. The dashboards are very intuitive and similar to SQL. They are easy to set up and get running.
What needs improvement?
The query language is pretty slick and easy, but it is not consistent in parts. Some of it feels a little esoteric. Personally, some of my engineers are coming from SQL or other languages. Some things are a little bit surprising in Splunk and a little bit inconsistent in their querying, but once you get use to it and once you get use to the field names and function names, you can get the hang of it. However, if it was a bit more standardized, it might be quicker to get it up and running.
I would like additional features in different programming models with the support for writing queries in SQL or other languages, such as C#, Java, or some other type of query definitions. I would also like a better UI tool for enhancements of advanced visual query editors.
For how long have I used the solution?
One to three years.
What do I think about the stability of the solution?
It is pretty stable, though it has gone down from our usage. We do need to keep an eye on our query volumes. Right now, it is too easy for a user to write a query, run it, make it available in polling mode (real-time mode), and bring down the server. Some more safety alerting would help and be beneficial.
We do have to educate developers on how to not blow it up. It is a little to easy to write an expensive query and overly stress the system. This could be improved. Overall, once you have people who know what they are doing, it is very stable.
What do I think about the scalability of the solution?
Our environment is on-premise, and it is big. We have a couple hundred users. However, it was slow and unavailable at times before we trained all the engineers on how not write a long, constantly polling query.
How is customer service and technical support?
Our internal tools team did work with the Splunk support team extensively. I was not directly involved, but from my point of view, they were able to fix and resolve issues within a day or less, so they have been okay
How was the initial setup?
It is early days right now to evaluate the integration and configuration of Splunk in our AWS environment. We are just starting to integrate it with regular stuff. While I think it is okay so far, I really do not have enough information.
What was our ROI?
Most of our return on investments have been through faster error resolutions. Our meantime to recovery has dropped for issues. We can often fix things before the customer notices them. Whereas, when logging was done custom by each team in non-standard ways, it would take days to resolve issues that are now resolved in sometimes minutes.
Which other solutions did I evaluate?
We knew we were going to go with Splunk. It was the leader and the one we liked. We didn't consider any others since Splunk met our needs.
We chose Splunk because of the ease of the UI, querying, and creating dashboards. It has a standardized query language, which a lot of the IT staff were already familiar with it. It was the market leader from our prospective for our needs.
What other advice do I have?
Go with Splunk. A lot of people know how to use it because they have experience with it. It works well. While it has some pain points, it provides reports and data visibility.
It integrates great with Opsgenie, PagerDuty and Slack. We love the Slack integration, as works great with the Slack alerts.
We use the on-premise version in our data centers and we use the AWS version. We are just starting to migrate to the AWS hosted version, and I have not seen a difference.

Senior Threat Intelligence Analyst/Manager at a tech services company with 1,001-5,000 employees
Provides good visibility and threat hunting, but is expensive
Pros and Cons
- "The most valuable features of Splunk Enterprise Security are the enterprise search bar and the dashboards."
- "The high cost of Splunk Enterprise Security prevented us from using its full capabilities."
What is our primary use case?
I use Splunk Enterprise Security for threat hunting.
How has it helped my organization?
The end-to-end visibility provided in the dashboards is great for our needs.
Splunk Enterprise Security allows monitoring across multi-cloud, on-prem, and hybrid environments.
Splunk does a good job of ingesting and correlating data.
Splunk provides real-time monitoring.
The framework's features, such as the MITRE ATT&CK framework, are great.
Our MTTR has improved with Splunk. It has improved our investigation time.
What is most valuable?
The most valuable features of Splunk Enterprise Security are the enterprise search bar and the dashboards.
What needs improvement?
The threat intelligence management feature would benefit from a broader range of APIs for enhanced integration. This would facilitate seamless connection with various threat intelligence platforms, as some currently are missing APIs, making integration difficult.
The high cost of Splunk Enterprise Security prevented us from using its full capabilities.
For how long have I used the solution?
I have been using Splunk Enterprise Security for one year.
What do I think about the stability of the solution?
Splunk Enterprise Security has been largely stable, experiencing only a few brief periods of downtime.
Which solution did I use previously and why did I switch?
We use Splunk and Sentinel for different purposes mainly due to cost factors not because one is better. For example, we use Splunk more for network traffic.
What's my experience with pricing, setup cost, and licensing?
The price of Splunk Enterprise Security fluctuates based on the customer, but I believe it's quite costly, especially for our clientele. Furthermore, to access the full range of features, it's exceedingly expensive to have comprehensive log data.
When evaluating SIM tools and considering the cheapest option, Splunk Enterprise Security might be worth considering, especially for larger organizations. While cost is a factor, Splunk offers significant value, and I recommend it over focusing solely on price.
What other advice do I have?
I would rate Splunk Enterprise Security seven out of ten.

Flag as inappropriateInformation Technology Specialist at a healthcare company with 10,001+ employees
Provides information about what's going on in a simplified way
Pros and Cons
- "From my experience, the visual aid that it provides is most valuable. There are charts and other means to provide information."
- "Its user interface for everything other than the charts can be improved. Some parts of it can be simplified a bit, such as when importing documents that have the network traffic. When you're going through the information about the network traffic, you have to have the expertise, but even if a program is supposed to be for IT support, it is good to make it user-friendly because it gets easier to train people. When something goes wrong, the more difficult a program is in terms of UI, the harder it is to fix the issue."
What is our primary use case?
I went to a cybersecurity boot camp through Penn University, and we went over this topic for a decent amount of time. It was more of a testing environment where they gave us different file formats that we had to go through. We would upload those files to Splunk, and it would give us good examples of what it would look like under different circumstances, such as when an organization is getting hacked, when there is a DDOS attack, and so on.
How has it helped my organization?
It is a good way of seeing the network traffic as a whole. With network traffic, there are a lot of things going on, especially in a big organization. It organizes the information and makes it more usable for average people. If you use Wireshark, you'll get a ton of information, and it is super easy to get lost in it. Even if you put Wireshark on for about 30 minutes, you can very easily get lost. Splunk simplifies the information, and it gives you charts and different means of seeing that information, making it easily understandable for people.
What is most valuable?
From my experience, the visual aid that it provides is most valuable. There are charts and other means to provide information.
What needs improvement?
Its user interface for everything other than the charts can be improved. Some parts of it can be simplified a bit, such as when importing documents that have the network traffic. When you're going through the information about the network traffic, you have to have the expertise, but even if a program is supposed to be for IT support, it is good to make it user-friendly because it gets easier to train people. When something goes wrong, the more difficult a program is in terms of UI, the harder it is to fix the issue.
For how long have I used the solution?
I've been using this solution for a little while.
What do I think about the stability of the solution?
In terms of stability, I really liked it. I didn't see any issues as far as stability was concerned. Whenever I needed it, it was there. It was available, and it worked. It was pretty good.
What do I think about the scalability of the solution?
Its scalability seems pretty good. If you are working with a lot of information, it would be usable.
Its users would depend on the organization. Mostly network engineers, network analysts, and SOC analysts would be dealing with this.
How are customer service and support?
There were instructors who knew how to fix a lot of the issues. If there was an overarching issue, they would deal with it.
Which solution did I use previously and why did I switch?
At the boot camp, we also used Kibana, which looked a little bit more friendly, but when we got into the details, I liked Splunk a little bit more. It was more intuitive, and it did a little bit more on its own rather than Kibana. With Kibana, it felt like I had to hold its hand all the way through the whole process. There were 20 people, and I know a number of people were leaning towards Kibana. It just came down to personal preference.
How was the initial setup?
We saw some of the basics for deploying it within an environment, but it was very minimal.
It isn't complex, but there is a little bit of a learning curve. Once you get the hang of it, it is very easy to get in and do things, but there is definitely a learning curve. I am not speaking just for myself; other 20 or more students that were in that class at the time also had a difficult time getting the hang of it, but once you get the hang of it, it is smooth sailing. You can fly through the program. Making it a little bit more simplified would help.
What's my experience with pricing, setup cost, and licensing?
I remember Splunk being relatively affordable. Kibana was more reasonable, but you get more with Splunk. If I was suggesting something, I would probably suggest Splunk because it is better to pay a little bit more and get a lot more.
What other advice do I have?
I would advise making sure that your staff is very aware of how the program works. After one or two classes, I got the hang of it, and it felt like I knew everything that was there to know about it, but when we went into the next class, I realized that there is a lot more. So, if you are going to use the program, I would advise making sure that everyone is trained and everyone really understands it. You should take your time to go into the nitty-gritty. You can very easily think that you know everything, but when you make mistakes in Splunk, at least from my experience, it can get messy quickly. So, you want to make sure that everyone has a very good understanding of what they're doing so that you can keep everything organized and accurate.
I would rate it an eight out of 10. When we're getting into the nuts and bolts and looking at the data, it is an eight, but when we are just navigating through the website, it is a seven. Only its UI needs improvement. It isn't bad, but there is room for improvement. They should make it a little bit more user-friendly.

Lead Information Security Specialist at a tech services company with 1,001-5,000 employees
Provides end-to-end visibility and reduces the investigation time tenfold
Pros and Cons
- "Correlation search, in general, is valuable because it allows us to search multiple data sources easily."
- "The main issue that I have with it is that the field transformations sometimes overlap with those in Splunk Enterprise, and then you get permissions issues that lead to troubles."
What is our primary use case?
Generally, we leverage it to correlate all of our threat intelligence data with all of our log events to make researching them simpler.
How has it helped my organization?
Splunk Enterprise Security gives us a lot more visibility into the entire enterprise and makes our analysis simpler. It streamlines the process and makes it easier to handle it.
It is very important for us that Splunk Enterprise Security provides end-to-end visibility into our environment. It saves us all the time where we used to have to go from tool to tool to tool to track down issues. Splunk Enterprise Security has tenfold reduced the amount of time it takes to investigate any one thing.
Splunk Enterprise Security simplifies being able to pivot from one data point to everything else, and it does not matter where in the pipeline that occurred because you can see it all.
It has helped improve our organization’s ability to ingest and normalize data. It has been very impressive how it is able to handle all of that for visibility and tracking things down.
Splunk Enterprise Security has not yet helped to reduce our alert volume. Our alert volume has increased at this point because we are still getting used to it, but I see how it can reduce the alert volume.
It provides us with the relevant context to help guide our investigations. The biggest part of it is that when we go through the alerts and the notable events, we are able to pivot to information from data sources that are not necessarily in Splunk, and we are able to run the automated response actions.
Splunk Enterprise Security has helped reduce our mean time to resolve. I do not have the metrics, but it is a decent amount.
Every process has been streamlined. Things for which you have to bounce between multiple tools can be done in one place, which in its nature speeds everything up and reduces the manpower.
What is most valuable?
Correlation search, in general, is valuable because it allows us to search multiple data sources easily.
What needs improvement?
The main issue that I have with it is that the field transformations sometimes overlap with those in Splunk Enterprise, and then you get permissions issues that lead to troubles.
I do not have any additional features that can be included. From what I gather, Mission Control is already included in the next release, as is a lot of the Cisco threat data.
For how long have I used the solution?
I have been using Splunk Enterprise Security for about five and a half years.
What do I think about the stability of the solution?
It is quite good.
What do I think about the scalability of the solution?
I have not experienced any issues with the scalability, but I do not handle the scaling, so I cannot speak to that.
How are customer service and support?
I do not have to deal with them, so I do not have any information. Our administrators handle that side of things.
Which solution did I use previously and why did I switch?
I did not. We acquired Splunk around about the same time I joined the cybersecurity team.
How was the initial setup?
I do not handle the administrative part. I am more of a user.
In terms of the deployment model, I believe it is technically a hybrid deployment. I am not involved in the architecture, but I know we are not exclusively cloud and we are not exclusively on-prem. We use AWS.
What about the implementation team?
I know we had Splunk Professional Services for the deployment, but I was not involved.
What was our ROI?
I do not know what the cost is, but I would imagine we have seen an ROI because we are able to run our security team with fewer people than previously.
Which other solutions did I evaluate?
I do not know what we evaluated because I came to the company at the same time we got Splunk.
What other advice do I have?
I would rate Splunk Enterprise Security an eight out of ten. It is an amazing tool that provides so much visibility and streamlines so much. The main issues I have encountered with Splunk are the difficulties in configuration and keeping everything up to date as the data sources change.

Provides threat intelligence correlations and reduces lead time for identifying risks and threats
Pros and Cons
- "The solution's most valuable feature is threat intelligence correlations."
- "I'd love to see more integrations, which is one of the primary points of the key node with Splunk Enterprise Security."
What is our primary use case?
We use Splunk Enterprise Security for insider risk and security operations centers.
How has it helped my organization?
Splunk Enterprise Security primarily reduces our lead time for identifying risks and threats. Since a lot of the work is being outsourced or we depend on those new threat intelligence feeds, we're able to identify and triage them quicker. So, it leads to a quicker incident response.
What is most valuable?
The solution's most valuable feature is threat intelligence correlations. It's too hard to stay up-to-date on all the different data feeds yourself. So, having a tool that does it for you is very beneficial.
Splunk Enterprise Security has increased our alert volume because we now have new data to work with, and we're writing more alerts. We don't use the solution a lot for observability. Usually, our primary use case for Splunk Enterprise Security is cybersecurity.
It is extremely important to our organization that Splunk Enterprise Security provides end-to-end visibility into our environment. That's the primary reason we use it. We want the ability to do everything from one tool without having to trash back and forth and take that precious time.
Splunk Enterprise Security has helped reduce our mean time to resolve. We're at least twice as efficient with Splunk Enterprise Security at identifying risk, following up, tracing it throughout the chain, and resolving it. We still have various toolings, but over time, the goal is to nest everything into Splunk Enterprise Security to make it cohesive from end to end.
What needs improvement?
I'd love to see more integrations, which is one of the primary points of the key node with Splunk Enterprise Security. I would also like to see more admin capability to enable the health of Splunk Enterprise Security because, a lot of times, it's difficult to know when and why things are failing, especially for on-premises customers.
Splunk Cloud is a little clearer because it has more integrated support. For on-premises, it feels like sometimes you have to guess and then hope for the best. Troubleshooting some things related to Splunk Enterprise Security takes a lot of time.
For how long have I used the solution?
I have been using Splunk Enterprise Security for five years.
What do I think about the scalability of the solution?
The solution's clustering is great, but it could have easier containerization where it's more dynamic, and you can spin up and scale down as needed. Right now, Splunk is a very large expense for us as far as our cloud environment is concerned. Anything we can do to cut costs would be great.
Right now, we run the servers 24/7 and never change the size unless they're underpowered. We're spending a lot of money on off-hours to keep it alive, which is not ideal.
How are customer service and support?
We've got a lot of experience on our team solving Splunk, but the few times we used Splunk's technical support, we found them to be very effective and efficient. Occasionally, we'll forget to respond to them, and they'll follow up with us, which is usually the opposite of what you see. So, I've got nothing but good things to say about Splunk support.
How was the initial setup?
The solution's deployment was difficult because we were going through admin changes right as we were installing it. It took three admins over the course of five years to get it set up. I think if we had one dedicated admin from the start and kept them on the job until the job was done, we wouldn't have had nearly as much trouble.
What about the implementation team?
We used a reseller to implement the solution.
What was our ROI?
We have seen a return on investment with the solution.
What other advice do I have?
Splunk Enterprise Security is really strong, capable, and great at what it does. There are obvious areas of improvement, but it looks like Splunk has already identified them and is working on road maps to enhance SOAR integration and AI digital assistance for Splunk Enterprise Security. Once those are fully implemented, the product will further improve.
Overall, I rate the solution an eight out of ten.
