I work in security and use Splunk for endpoint and application security, use case development reports, etc. I haven't used Splunk much for threat intelligence. We have a threat intel feed configured, and we create use cases based on those and the recommendations by the threat intel team. If something isn't covered, we create a use case for it. For example, if an application has an authentication interface enabled, we check all their authentication mechanisms and all the login policies.

The solution speeds up our response by enabling us to automate some of the investigation steps
Pros and Cons
- "Splunk's interface is user-friendly, and it has apps and add-ons for most applications. We can easily normalize the data to make it readable and understand the logs. We easily get all the field extractions and enrichment done by using the apps and add-ons. This helps us understand the application logs because the raw data is useless unless we extract some useful information from it. These add-ons make it so much easier."
- "It would be nice if Splunk reduced the cost of training. Their training sessions are way too costly."
What is our primary use case?
How has it helped my organization?
Splunk speeds up our incident response by enabling us to automate some of the investigation steps, such as finding information about the user or the source of the incident on machines. We can then move directly into the remediation phase and assign those tickets to the remediation team. It also triggers automatic email alerts to the recipient user. If our security analyst wants to see the alert logs or anything, they can easily drill down to identify any information required.
It allows us to configure use cases involving our machine-learning toolkit, and we have an adaptive threshold in ITSI. Using these tools, we can eliminate false positives and do some whitelisting to weed out users who are performing benign activities. Removing the false positives reduces the incident response time.
We can start to see results immediately once we have achieved a steady state. For instance, we can easily show how much our mean resolution time for incidents has fallen and provide metrics in a way that is easy for our clients to understand.
What is most valuable?
Splunk's interface is user-friendly, and it has apps and add-ons for most applications. We can easily normalize the data to make it readable and understand the logs. We easily get all the field extractions and enrichment done by using the apps and add-ons. This helps us understand the application logs because the raw data is useless unless we extract some useful information from it. These add-ons make it so much easier.
Dashboards are useful when we present things to management. They want the numbers and the results. The leaders aren't interested in what we are working on. We need some visualization for our presentations. Splunk has beautiful and useful visualization and dashboard alerts. We can easily create visualizations using the available options and create different types of charts, reports, and graphs that are easy for management to understand. We can also provide our leaders direct access to the dashboards, so they don't need to reach out to our team to get this data or we can automatically send them the reports via email.
Splunk has several useful features, like asset and identity management. If we integrate our asset and identity management properly in this log, it's effortless to identify the user, device, or asset. We can get all the details if we integrate those things into the lookup engine.
What needs improvement?
It would be nice if Splunk reduced the cost of training. Their training sessions are way too costly.

Splunk Enterprise Security
May 2026
Learn what your peers think about Splunk Enterprise Security. Get advice and tips from experienced pros sharing their opinions. Updated: May 2026.
902,270 professionals have used our research since 2012.
For how long have I used the solution?
We have used Splunk for around seven years.
What do I think about the stability of the solution?
Splunk is highly stable if you meet all the prerequisites and have enough physical memory for your local storage.
What do I think about the scalability of the solution?
If you use the cloud version you can scale as much as your licensing allows. It's easy to scale, upgrade, or add instances according to your needs.
How are customer service and support?
I rate Splunk support 8 out of 10. They're good, but I think there is room to improve because Splunk is the market leader, and they should strive to provide the best possible support.
Which solution did I use previously and why did I switch?
I previously used QRadar and ArcSight. Splunk is one of the top products. Compared to Sentinel or QRadar, Splunk is the market leader in features and security. You can integrate application, physical, or cloud security and onboard those logs into Splunk, then tailor it to your requirements.
How was the initial setup?
I've worked on multiple deployment models for Splunk, including hybrid, cloud, and on-prem. The deployment is straightforward. We do a POC and then scale it based on our requirements.
What was our ROI?
I feel like Splunk is worth our investment.
What's my experience with pricing, setup cost, and licensing?
The cloud version of Splunk is somewhat expensive, but it does provide some flexibility because you do not need engineers to manage the system. Everything is hosted in the cloud because it is a SaaS service. It depends on the usage. It is costly, but everything good thing comes at a price.
What other advice do I have?
I rate Splunk Enterprise Security 9 out of 10.

Lead Administrator at Wipro Limited
We can create dashboards, speed up our security investigations, and reduce alerts
Pros and Cons
- "Splunk has a wide range of features that customers use to find and analyze all kinds of logs."
- "The price has room for improvement."
What is our primary use case?
We provide comprehensive infrastructure support and ingest mine data in three ways. The first is Agent-based where the information is sent from client machines to an agent. The second is TCP port forwarding where data is sent to Splunk through an open port. The third is the HEC token. We then use the Splunk DB Connect app to ingest data as per the client's requirements.
How has it helped my organization?
We are currently onboarding data from AWS to GCP. We are moving data from on-cloud to our production and deployment level environment. Additionally, the data is being added to the services on those machines. To forward the logs to Splunk, we have created a default index, which is a way of storing data in a particular way. We have created the index based on the requirements of the data storage.
Currently, we are ingesting all kinds of government security PI data. Similarly, we can ingest any kind of confidential data into Splunk using masking. This allows us to filter the data and mask sensitive information. For example, if a user account number has ten digits, we can mask out the first six digits so that only the last four digits are visible. We ingest this kind of confidential data into Splunk, and we also ingest PI data and Splunk governance data.
We are using the threat intelligence management feature. We have a separate security team, called a soft team, which is responsible for finding vulnerabilities, threats, and malware alerts in our Splunk environment. We use the threat intelligence management feature to identify any suspicious activity that may be coming from outside users. The soft team continuously monitors these alerts and creates proxy alerts to identify any potential threats.
Splunk's insider threat detection capabilities help us to easily identify threats by using Splunk queries. We have predefined Splunk Insight and are also using the one in the app, which is configured on top of Splunk machines. This allows us to quickly identify how many unknown IPs are syncing into other machines, and we can use this information to identify threats.
We use threat pathology and MITRE ATT&CK. I am currently supporting a financial institution with its infrastructure, which is split into two teams: one for complete infrastructure support, including hosting and operations, and the other for security-related matters. My team is continuously investigating new security threats, so we will take care of the onboarding process. As part of the infrastructure support team, I am responsible for handling all onboarding tasks. If I encounter any security concerns, I will escalate them to the SOC team.
We have a lot of operations using the Mission Control feature in Splunk.
Splunk helps us analyze malicious activities and detect breaches. We are using a Splunk SaaS application in a multi-class environment. To maintain high availability with zero downtime, we have maintained close to 70 indexes and 50 searches. Splunk provides us with alerts from the entire infrastructure, which helps us maintain our service. We use Splunk Mission Control to iron out any issues. For any special needs, we can go to Mission Control to verify and mitigate alerts.
Splunk Enterprise Security has helped us reduce our alert volume. Splunk currently ingests five terabytes of data, and we can set parameters to exclude rotational works and backlogs to reduce the number of alerts.
Splunk Enterprise Security has helped speed up our security investigations.
What is most valuable?
Splunk has a wide range of features that customers use to find and analyze all kinds of logs. For example, they can use SQL queries to identify vulnerabilities. Additionally, they can create dashboards to visualize and filter their data, and to create real-time alerts when thresholds are exceeded. Splunk Vision is a popular tool for data modeling and visualization and is used worldwide.
What needs improvement?
The price has room for improvement.
For how long have I used the solution?
I have been using Splunk Enterprise Security for five years.
What do I think about the stability of the solution?
We are maintaining a multi-cloud environment across multiple regions, and for the last two years, Splunk Enterprise Security has maintained a 99.999 percent uptime.
How are customer service and support?
We open cases on behalf of our customers with Splunk. If the technical support resolution is not up to par, we request a meeting call to work with the support team and resolve the issue for our client.
Which solution did I use previously and why did I switch?
We also use the Red Hat OpenShift enterprise Kubernetes container platform. OpenShift is a more popular container tool with excellent support, but all of our OpenShift deployments are on-premises, along with production clusters around the world.
How was the initial setup?
For the deployments, we scan the data to ensure that the Splunk machines can support it. If we identify anything on the machine, we ask the customer to remediate the issue by upgrading the version of Splunk. Most of our customers are using version 8.3.3.
What other advice do I have?
I would rate Splunk Enterprise Security nine out of ten.
Organizations that value their security should not choose the cheapest SIEM solution. They should expect to invest in a SIEM solution that can meet their specific needs, even if it means spending more money.
Monthly patching maintenance is required.
Which deployment model are you using for this solution?

902,270 professionals have used our research since 2012.
Reasonably priced, helps with compliance, and saves a lot of time
Pros and Cons
- "The most useful feature for me is the ability to create different kinds of alerts and set a different kind of denominator that will capture the real event. That is helpful for a power user like me."
- "It will be helpful for customers if they can create some real-world cases, and we can find a case study to align with. I know that Splunk has tremendous potential. We only include a tiny piece of it. There is a lot of stuff that we need to learn. If Splunk can provide more real-time examples, that will be helpful for customers."
What is our primary use case?
We gather all the security logs from all the endpoints, network appliances, and the security filter. We have set up automatic alerts that are sent to system administrators, so we have pretty much real-time alerts about anything that happens.
How has it helped my organization?
Splunk Enterprise Security has definitely improved my organization. First of all, it helps with compliance. Our organization has something called scorecard requirements. It is an annual self-check checklist. Having alerts set up is one of the requirements, and secondly, we have a local administrator who gets the alerts. That makes our job a lot easier. So, we pretty much know what is going on in a real-time setting.
We are the judicial branch of the government, so we are pretty much into our private cloud. We do have a setup to monitor our private cloud but not outside our organization. If we can monitor one cloud, multiple clouds will not be hard at all. It is easy.
Splunk has absolutely reduced our mean time to resolve. Knowing on time and having firsthand information is very helpful for any organization. We are able to capture what is going on, and the visibility of it is absolutely tremendous. I cannot provide the metrics, but it has saved a lot of time.
Splunk has absolutely improved our organization’s business resilience. We have been using Splunk for the last six or seven years, and I cannot imagine a life without Splunk.
In terms of Splunk’s ability to predict, identify, and solve problems in real-time, this is something that we will look into. We have not yet looked into machine learning, AI, and all of Splunk. Currently, we are more in the reaction mode, but we are trying to get more in the protection mode or have more proactive measures. We have not got to that point yet, but we will definitely be there.
What is most valuable?
I am not into the administrator type of setup. I am more like an advanced user. The most useful feature for me is the ability to create different kinds of alerts and set a different kind of denominator that will capture the real event. That is helpful for a power user like me.
What needs improvement?
Splunk conferences are very helpful for networking and talking to folks who have a similar situation. It would be helpful for customers if they could create some real-world cases, and we can find a case study to align with. I know that Splunk has tremendous potential. We only include a tiny piece of it. There is a lot of stuff that we need to learn. If Splunk can provide more real-time examples, that will be helpful for customers.
For how long have I used the solution?
It has been six or seven years.
What do I think about the scalability of the solution?
Splunk has a reputation for being scalable. You can start small, and if your demand increases, you can scale your platform. Splunk does a good job. It allows customers to have scalability so that they can expand their capacity. I would rate it a ten out of ten in terms of scalability.
How are customer service and support?
In our company, we have a Splunk consultant who is very good at providing a solution. So far, I have not had any problem that is unresolved. I would rate their support a ten out of ten. In this industry, there is good support, and there is bad support. Splunk's support is more like Cisco's support. It is pretty good.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We used something else, but I do not remember the name. Splunk is what we have been using for a long time. It is more advanced in terms of IT security. There is more scalability and the capability to do a lot of different things on multiple platforms. This is where it is more advanced than other products.
How was the initial setup?
I was not in the deployment team, but I was involved in the early stage of evaluating all different kinds of products.
What was our ROI?
There are a lot of things for which you can measure a return on investment, but security is something on which it is hard to put a dollar value and measure how much return you have got. However, in terms of helping the administrator or helping the company to put security in place, Splunk does a great job. I cannot imagine a life without Splunk.
What's my experience with pricing, setup cost, and licensing?
The pricing is a little bit on the higher side, but looking at what Splunk provides us, it is reasonable.
Which other solutions did I evaluate?
We evaluated what was on the market, and fortunately, we picked Splunk. Looking back, it was the right decision.
What other advice do I have?
Splunk is moving in the right direction and providing better and more mature products. This is my fifth conference, and I see the progress. I see Splunk bringing in all new products. They are pretty much in line with the security trends. They have improved a whole lot to meet customers' needs.
I would rate Splunk Enterprise Security a ten out of ten.

It's really good at consolidating a lot of data from different sources and generating summaries
Pros and Cons
- "It has been really good at consolidating a lot of data from different sources. It's really good at generating summaries."
- "It would be nice if Splunk provided a little more documentation and instructions on how to upload. The steps are short, but sometimes it's not so intuitive."
What is our primary use case?
Our primary use case is mostly for monitoring security events. We have different endpoints, like router switches. It collects a lot of data and we create reports.
We also use Enterprise Security to send alerts out. I'm still relatively new. I mostly work for the SPL side of things.
How has it helped my organization?
It has been really good at consolidating a lot of data from different sources. It's really good at generating summaries.
It's exciting to hear that SPL2 is rolling out. We look forward to using that more, especially for the data ingestion part of things.
What is most valuable?
In the context of apps, we use a lot of search and reporting. We create many searches and reports, that quickly summarize a lot of information. That's the part that I mostly look into. That has been very valuable. I also like the dashboards and visualization features.
Its ability to provide end-to-end visibility into our environment is important. It helps a lot, especially when other users or stakeholders want that information. So being a little more transparent, but being mindful of the compliance and rules associated with that. It makes it really easy to communicate with people. They want statistics fast. The ability to quickly pull it out without a hassle is very valuable.
We use Splunk to try to reduce the number of random alerts sent out. We're trying to consolidate a lot of functions. That has been very valuable and helpful for us.
The logging system has been a great help to us. Sometimes when we try to integrate some functions, we're not sure what errors happened. We look into the logging system, and it provides so much information.
These optimization examples have reduced the meantime to resolve. It has been reducing cutting time.
It definitely helps our business resiliency a lot. We have a specialized cybersecurity office and on-prem technology and they really like to use Splunk. It has been addressing a lot of concerns and it is able to output the data that people are looking for. It's able to predict and identify a lot of functions.
Splunk Enterprise Security has been a great help to us in consolidating our tools. It's definitely been pulling a lot of data, especially from the network side of things. We look at it for baseline security tests. Splunk has a lot of apps and add-ons that we have been using Enterprise Security for.
What needs improvement?
I currently use Splunkbase and some of the add-ons. Integrating into our apps has been very straightforward. It would be nice if Splunk provided a little more documentation and instructions on how to upload. The steps are short, but sometimes it's not so intuitive. It would be nice if there were more user-friendly help guides.
For how long have I used the solution?
I have been using Splunk Enterprise Security for six months.
What do I think about the stability of the solution?
It has been very reliable. We haven't encountered downtime that I know of.
What do I think about the scalability of the solution?
Splunk works with companies that are a lot bigger than us. We're medium-sized. I have faith that we can scale.
How are customer service and support?
For technical support, I look at the online community, which has been a great help. I haven't used Splunk support directly.
The forum is easy to use. I would rate it a nine out of ten. Sometimes the response time is slow.
How would you rate customer service and support?
Positive
What other advice do I have?
I would rate Splunk Enterprise positively. I hear from coworkers that there could be tweaks. I would give it an eight out of ten.
In the SPL default, everything's crunched together. The formatting could be neater. When I write it in the search head, it has a lot of information in one small area. It could have a friendlier user interface.
Which deployment model are you using for this solution?
On-premises

The incident review functionality gives a good overview of security incidents
Pros and Cons
- "The solution's most valuable feature is the incident review, which gives a good overview of our security incidents."
- "You can run a script from an event, but it needs many clicks to run that integration, which could be made easier."
What is our primary use case?
We develop use cases for Splunk Enterprise Security all the time. I mostly work with the SOAR platform to ingest those use cases.
How has it helped my organization?
Splunk Enterprise Security helps our organization because we use it daily to solve our security use cases. We have incidents every day.
What is most valuable?
The most valuable feature is the incident review, which gives a good overview of our security incidents. I also like the solution's search functionality, which makes it easy to find things.
Splunk Enterprise Security generates our alerts, and we would have to refine the searches if we want to reduce them.
It's very important to our organization that Splunk Enterprise Security provides end-to-end visibility into our environment.
Splunk Enterprise Security has helped reduce our mean time to resolve and helped improve our organization’s business resilience.
What needs improvement?
The incident review could definitely be improved in many ways. It should be easier to run integrations from it. You can run a script from an event, but it needs many clicks to run that integration, which could be made easier.

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.

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.
Which deployment model are you using for this solution?

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.

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.
