Helps improve our incident response time, and provides great visibility, but the deployment is complex
Pros and Cons
  • "Splunk Enterprise Security's dashboards are a key asset."
  • "The presence of multiple layers creates a significant challenge for monitoring across cloud environments."

What is our primary use case?

We use Splunk Enterprise Security for threat detection on our network devices.

How has it helped my organization?

Splunk Enterprise Security excels at threat detection. We've developed multiple correlation searches leveraging security data. These searches identify threats and categorize them by urgency level, enabling our security analysts to prioritize and take swift action.

Splunk Enterprise Security has helped us improve our incident response time. We achieve this by ensuring our queries are completed in near real-time.

Access management focuses on storing and managing access controls, while identity management deals with user identities. For example, if we want to find IP addresses associated with CrowdStrike, we can use access management to look up their IP ranges. Then, we can check if any IPs match by adding them to a specific identity management lookup. Finally, by leveraging the combined identity and access management features of Splunk Enterprise Security, we can create correlations between these entities.

The security dashboard can be customized to display the information we need most quickly. It typically has seven to eight panels, each dedicated to reflecting specific data. While some initial data load time might be present, clicking on a specific panel will display its information as soon as possible. There can be delays in traditional dashboards when searching for specific data. To optimize this, we can create "base searches" within each panel. These predefined searches cover commonly used queries and fields. Alternatively, we can create a "summary index" that holds a longer span of pre-processed data. This summary index allows even large datasets to be displayed quickly when accessed through the dashboard.

Splunk enhances our team collaboration regarding security incidents. When a threat alert is received, we can click on it and choose "investigation in progress" from a dropdown menu. This selection redirects us to a dedicated investigation page for further details. For in-depth analysis, we can drill down into the logs to pinpoint the source of the issue. Additionally, the platform allows us to contact network devices to determine the root cause. Once the issue is resolved, we can close the investigation.

We monitor both AWS and GCP environments using Splunk Enterprise Security. 

Splunk provides threat intelligence capabilities that can be valuable. This, combined with the comprehensive set of dashboards available, allows us to effectively monitor for threats. We can also create custom apps within Splunk for threat detection. These apps can include custom dashboards or reports that display specific information. For example, we could create a dashboard that shows the number of users accessing unknown URLs or another that monitors a particular device for suspicious activity. An example of suspicious activity might be a device where the print command is being executed repeatedly but failing each time. This could indicate a malfunction or, potentially, a malicious attempt to exploit the system. Similarly, a sudden spike in activity, such as millions of clicks on a specific device within a short timeframe, could also be a sign of a threat. By monitoring these parameters within Splunk's threat detection features, we can identify and investigate potential security incidents.

Splunk provides valuable visibility across multiple environments. Whether we have an on-premises or cloud architecture, Splunk offers self-monitoring capabilities. Additionally, depending on our environment, we can leverage existing monitoring tools. For on-premises deployments, we can utilize the Martin Console alongside Splunk for comprehensive monitoring. Cloud environments often come with built-in monitoring handled by the cloud provider's support team. In such cases, Splunk can focus on applications and custom log data for deeper insights.

The threat topology provided by Splunk gives us a comprehensive overview of potential threats. By analyzing queries or notable events, we can identify and neutralize these threats.

Splunk does a good job of analyzing malicious activities.

Splunk has improved our organization's decision-making by centralizing all the information in our environment and allowing us to access multiple dashboards and reports in one place.

Splunk has helped us reduce our alert volume. By using Splunk, we can identify the root causes of failures, which in turn leads to a decrease in alerts.

Splunk accelerates our security investigations by enabling us to resolve issues and document them in Standard Operating Procedures or knowledge-base articles. This facilitates a swifter response to similar incidents in the future.

What is most valuable?

Splunk Enterprise Security's dashboards are a key asset. They offer comprehensive visibility across our entire environment, allowing us to diagnose and address security issues directly from the interface.

What needs improvement?

I would like Splunk to offer a quicker and easier way to run queries.

Splunk could improve its cost-efficiency for our organization by offering pre-built architectures tailored to specific environments. This would provide a clearer picture of required licenses and their implementation, ultimately reducing licensing costs.

The presence of multiple layers creates a significant challenge for monitoring across cloud environments.

914,109 professionals have used our research since 2012.

For how long have I used the solution?

I am currently using Splunk Enterprise Security.

What do I think about the stability of the solution?

Splunk Enterprise Security is a very stable product, but there are occasional bugs that can appear.

What do I think about the scalability of the solution?

We can scale Splunk Enterprise Security up or down depending on our demands.

How are customer service and support?

The Splunk support team is helpful. For complex issues or on-demand requests, we raise cases with them. On-demand requests requiring impactful solutions are paid. However, for UK-based users, standard support is free and usually resolves issues efficiently. In some cases, the support team rushes to provide a solution without even looking at the issue.

How was the initial setup?

The initial deployment can be complex. It involves creating multi-site clusters for each location and configuring a cluster master for each. This is because the cluster master will replicate data across multiple sites, making the environment more complex.

Four people were required for the deployment.

What other advice do I have?

I would rate Splunk Enterprise Security 6 out of 10 because of the complexities that occur at times.

I highly recommend Splunk Enterprise Security for organizations seeking comprehensive security monitoring. Splunk offers a centralized platform to collect and analyze vast amounts of security data. This empowers us to gain full visibility across our entire IT environment, including applications, user activity, and potential security threats. Splunk provides insightful dashboards, reports, and real-time alerts to help proactively identify and address security issues.

While cost is a consideration, prioritizing features over functionalities for SIEM solutions can be risky. It's best to identify your business needs first and then choose an SIEM that offers the most relevant benefits to address those needs.

Splunk Enterprise Security is deployed across multiple locations and departments within our organization.

Splunk Enterprise Security required maintenance.

Which deployment model are you using for this solution?

User-friendly, feature-rich, and best support
Pros and Cons
  • "It is user-friendly. It is more effective than other solutions. The support and help for troubleshooting and the documentation from Splunk make it very effective."
  • "The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost."

What is our primary use case?

There are many use cases. Most of the use cases are related to security, data integration, and data sources. 

How has it helped my organization?

Splunk Enterprise Security helps with real-time detection. When we integrate any data source, if any external IPs or external devices are accessing that data source, we get notified. We get alerts based on the use cases we develop.

Splunk Enterprise Security has improved the incident response time a lot. Splunk is doing log ingestion, and it is also used to search the database for issues. It is ingesting and identifying. All that is happening in a single solution.

Splunk Enterprise Security is very easy to use. We can monitor anything. We can monitor and integrate any type of applications and servers. It is very easy and effective. I work with different security tools, but none of the security tools has these many features.

Splunk's documentation is clear. Irrespective of the environment we are working in, we have clear documentation.

One of our clients is using the Threat Intelligence Management feature. The actionable intelligence provided by the Threat Intelligence Management feature is very good.

I have been working with different vendors. Splunk Enterprise Security is a very effective and user-friendly tool. Whether it is Sentinel, LogRhythm, or QRadar, each one of them has its own limitations, but Splunk has all the features.

Its benefits can be realized very quickly. It does not take lots of days or months.

Splunk Enterprise Security has helped to reduce our alert volume. There is a 60% to 70% reduction.

Splunk Enterprise Security has helped speed up our security investigations.

What is most valuable?

It is user-friendly. It is more effective than other solutions. The support and help for troubleshooting and the documentation from Splunk make it very effective.

It has multiple features. It has data integration, search, reporting, and alerting.

It does not need any advanced programming. It only requires basic programming.

What needs improvement?

In terms of features, it does not need any improvement. Everything is good so far. The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost.

For how long have I used the solution?

I have been working with Splunk for more than 7 years. I have worked with Splunk Enterprise, Splunk Enterprise Security, Splunk Cloud, and on-prem Splunk.

What do I think about the stability of the solution?

It is very stable. We never had any issues or bugs.

What do I think about the scalability of the solution?

Its scalability is good.

How are customer service and support?

The support from the Splunk side is very good. They provide the best support.

How would you rate customer service and support?

Positive

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

I have used Sentinel and QRadar. I switched because of the advanced features, support, and good documentation. It is very effective. It is the best solution. The only problem is the cost.

How was the initial setup?

I have worked with cloud deployments and on-prem deployments. Its initial setup depends on the environment. It is sometimes complex, and sometimes, it is very easy. We also get good support from them.

Our implementation strategy has 3 phases. We first go for development, and then we go for Pre-Prod. After that, we move to Prod.

What about the implementation team?

Currently, I am the only one handling the deployment, but when it comes to operations, we need at least two to three people.

It requires maintenance. Generally, 2 people are required, but for my clients, I am the only one who is taking care of the maintenance.

What was our ROI?

We have seen an ROI.

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

It is expensive. I work for multiple clients. I am working for more than 5 clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel.

What other advice do I have?

I would recommend Splunk Enterprise Security to anyone who is looking for a similar solution. This is the only solution with all these features.

I would rate Splunk Enterprise Security a 9 out of 10. It is stable, user-friendly, and feature-rich. It is very helpful. Even though it is expensive, the stability, support, and technical documentation make it very effective.

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?

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. 

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.

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. 

How would you rate customer service and support?

Positive

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.

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.

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."
  • "From time to time, there are some glitches with stability; some logs are missing, and whenever there is something wrong with Splunk Enterprise Security, our external SOC team needs to raise a ticket and it can be time-consuming to wait for them to reply."

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.

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."
  • "The UI sometimes can be laggy and not responsive."

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.

Investigation dashboard provides a lot of value, end-to-end visibility, but multi-tenancy is not there
Pros and Cons
  • "The compatibility with the add-ons helps us add more data in the same compatible format and use data models to elaborate and make it faster."
  • "Stability is there, but every release has some bugs."

What is our primary use case?

The main use cases are with the firewall, DNS, and Windows events. These are the three basic ones to start with. Once they're done with all the compatibility and introductions, custom use cases will follow.

How has it helped my organization?

It's currently in the implementation phase. But, it will surely improve response time and make it easier to collect and check everything in one place. Instead of going to multiple dashboards and running multiple queries, all can be integrated into one dashboard. You can just click and then go drill down into deeper levels and get more information.

Splunk Enterprise Security provides end-to-end visibility into our environment. It's very important because: 

  1. This tool is used as SIEM implementation. End-to-end visibility is really important in such a case; if something is missed, it's an error. 
  2. Also, we belong to the retail sector with over 700,000 employees. We have a lot of endpoints and everything is open, so end-to-end visibility is essential.

It helped our organization to ingest normalized data. With Windows, DNS, firewalls, and the open use cases we've checked, we've gotten more data in. The compatibility with the add-ons helps us add more data in the same compatible format and use data models to elaborate and make it faster.

The investigation dashboard provides a lot of value. In the same dashboard, we get all the drill downs, raw events, and information about what the particular user is doing or where the vulnerability started, all in the same dashboard.

It helps us reduce our mean time to resolve. Now, we can see all the incidents on a single dashboard and it could be assigned to the analysts at the same time on the incident review. People can start working on it right away, so it does reduce the mean time to respond.

Splunk's unified platform helps consolidate networking, security, IT, and IT observability tools. But our major focus or use case is more on the security side. We don't use observability, so we just use logs, matrices, and other security-related features.

What is most valuable?

Incident review is pretty valuable. You can have everything in one place, review it, and assign things to analysts, and they can work on it. 

We also have different teams segmented; it is not one team. So, we brought that using the teams method in Enterprise Security, which I think most people are not using. This way, different users have different dashboards or lists of incidents.

What needs improvement?

One thing is multi-tenancy, which is not currently not there. The concept of Enterprise Security assumes only one team using Splunk, but in many companies, including ours, that's not the case. We have multiple security teams operating under one umbrella, with different people using it for different smaller companies. If multi-tenancy could be incorporated, it would surely help us. 

For how long have I used the solution?

We started with it last year. We integrated it last year, and the SOC team is now handling it. They're making it SIM compatible, introducing the first few use cases, and working with the data. 

So, we bought the license nearly a year ago, and started implementing it about six months ago.

What do I think about the stability of the solution?

Stability is there, but every release has some bugs. For example, in this release, indexes were down, searches were down, and the monitoring console wasn't working. So, it's a bit tough.

What do I think about the scalability of the solution?

It's still being implemented, and a lot of work needs to be done. But, considering the pricing and everything, I would give it a seven out of ten. It does have a lot of use cases, but a lot of work has to be done beforehand. Our data wasn't totally SIEM compliant because we used prebuilt solutions and changed the data format.

How are customer service and support?

We use Splunk Operator on Kubernetes, so it's not on-prem or Splunk Cloud. Customer support is not good at all.

For example, we upgraded the system on Saturday and raised an incident. With Operator, you can only raise a P3 incident, so we needed to escalate it and get the developers involved. Support cannot handle such cases. We always have to get the developers involved to get the issues fixed. This happened very recently. But it is very common; the support for Kubernetes is zero.  

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

The company didn't have a SIEM solution. It was more of SOAR, so we used FortiSIEM for that. We still use it. 

How was the initial setup?

Setup is not that difficult. You just have to install the search head cluster and a normal app. Data normalization is the main thing required for Enterprise Security. SIEM compatibility is the most important thing. If it's not there, then it won't work.

The deployment of the solution is pretty simple, if your data is SIEM compliant. If not, then you need to make it SIEM compliant. Otherwise, you cannot use the solution.

What about the implementation team?

We have a Splunk partner that helps us with integration and other stuff.

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

Pricing is a bit costly. It always is.

Which other solutions did I evaluate?

We considered a couple of other brands. We ran a couple of POCs with other enterprise tools.

Since we've been using Splunk for nearly four years, it was easier to incorporate Enterprise Security. We did try other SIEM solutions like Fortinet, but since Splunk was already there in place and had all of our normalized data, it made more sense to use Enterprise Security.

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.

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.
