Great for identifying application interdependencies with helpful support but needs better visualizations
We're just trying to identify the application interdependencies, which normally reside on different servers, including web servers, database servers, enterprise service bus, et cetera, up to your presentation layer before we start moving stuff around. Normally, the reason why we use these tools is to understand what assets we have, where they're deployed, and how they enter and operate before we decide to go move something from point A to point B. The solution is going to allow me to establish a wave or migration plan where you have different waves of migration and then you actually have move groups to try and get your application moved from A to B seamlessly. A to B could be on-premise to on-premise. It could be on-premise to cloud. Et cetera. The solution can tell me what components can I deploy, for example, into a cloud space, without having to refactor my applications since that can be quite time-consuming and costly.

Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Not only can you look at the protocol import level. It also has a live PCAP analysis."
"This solution is more applications reference architecture focused. Its benefit is that it specializes in that space."
"Wire data analytics."
"The most valuable feature is the way it handles data, from Layer 2 up to Layer 7. We can see everything that happens in the network."
"There are many valuable features in this product, but probably the biggest is the customization capability it has."
"The most valuable features are security detections, perimeter detection, dashboards, and alerts."
"It provides a lot of analytics with the underlying AI engine, and it is a lot easier than other solutions. There are some products that do automated AI-based detection and drawing up charts, but for network monitoring and all of the monitoring aspects, it is quite a nice tool. It is very convenient for business users because they get more or less a lot of data readily available. If you're familiar with the Splunk query language, you can pretty much do whatever you want."
"Splunk is user-friendly. We can easily customize the monitoring script."
"Search language is easy to understand and teach to new users."
"The ability to manage large amounts of generated data and to protect all devices from unauthorized use are the most valuable features."
"The site is constantly up, and it's been really easy to adjust the data."
"I have not seen any outages in the product in the past two years that it has been running in our company, so I think it is good when it comes to the stability part."
"The initial setup is simple, not very complex. Initial deployment takes around 10 to 15 minutes to set up the entire base for Splunk including all three tiers."
"The product has a good security posture."
 

Cons

"They either have to go broad or decide what their bread and butter is and get really good at that."
"I would improve the Rule-Based Access Control (RBAC) by providing granular access control to the data."
"Network visibility is something that needs to be improved."
"They have a new solution, ExtraHop Reveal(x), and I think it needs improvement."
"We'd like to see a local presence within the region in order to have seamless service whether it's the support, the implementation, or professional services."
"This solution would be improved if it had the ability to retain data longer."
"Given the ever-increasing number of threats, I would like Splunk to update its threat signatures more frequently."
"Areas of Splunk Enterprise Security that could be improved include the need for training and certifications. We are planning to do certifications, and there are many features, such as risk-based score and score detection, where the current training doesn't provide visibility to the analyst."
"Splunk can improve regex/asset analysis as we do not want to crawl until it is done."
"The solution could use a different licensing model."
"I feel as though a major focus of upcoming releases should be set on Machine Learning, Predictive Analytics, and I would enjoy to see more security focused add-ons and apps developed by the vendor."
"I've never had too many issues with the stability. Years ago we had indexes crash but that was more on us. We didn't understand how to properly size Splunk."
"I feel the solution to be too slow."
"Sometimes, there is latency in the logs."
 

Pricing and Cost Advice

"The pricing is higher than other solutions, but with such good features, I think it's worth it."
"The pricing is fair considering the value provided."
"The price of this solution for our environment is about £650,000 ($855,000 USD) for three years."
"Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors."
"I assume that the pricing is reasonable, because if it was too costly, there are other alternatives."
"The price of Splunk is reasonable."
"Splunk Enterprise Security is priced lower than competitors."
"The pricing of Splunk Enterprise Security is somewhat high, but comparing it with its benefits, it's acceptable. It depends on the type of business."
"It is expensive. I used to buy it early on, but then they combined it into a higher-up organization. They buy it for multiple systems now. Last time, I paid around 60K for it. There is just the licensing fee. That's all."
"It would be nice if the pricing were cheaper. However, we did purchase it."
"Splunk Enterprise Security is expensive."
