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

"Wire data analytics."
"There are many valuable features in this product, but probably the biggest is the customization capability it has."
"Not only can you look at the protocol import level. It also has a live PCAP analysis."
"The most valuable features are security detections, perimeter detection, dashboards, and alerts."
"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."
"This solution is more applications reference architecture focused. Its benefit is that it specializes in that space."
"We can automatically suspend or terminate suspicious sessions."
"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."
"We can extract the metrics we want on the dashboards. We are able to react to the incidents."
"The product is generally stable and forgiving."
"It allows the centralization of data and makes possible new sorts of correlations that were previously impossible using traditional SIEMs such as ArcSight or QRadar."
"The correlation searches are most valuable just because we are able to do things like RBA."
"Our clients are easily able to modify and evolve their implementations."
"We used it to create a custom anomaly detection data model to monitor the activity of our back-end services on an hourly basis relative to the past three months of activity."
 

Cons

"Network visibility is something that needs to be improved."
"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."
"They either have to go broad or decide what their bread and butter is and get really good at that."
"This solution would be improved if it had the ability to retain data longer."
"I would improve the Rule-Based Access Control (RBAC) by providing granular access control to the data."
"They have a new solution, ExtraHop Reveal(x), and I think it needs improvement."
"We'd like to have the number of devices covered under the license to be increased."
"The product is relatively expensive."
"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. They should offer training based on the features we use."
"I feel the solution to be too slow."
"It requires a significant amount of relatively complex architecture once you push past the single server instance."
"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."
"They can improve their support teams. They can also improve their capability of ingesting data from different IoT sources."
"Splunk needs to be able to hold more days of data. At the moment it only holds three months of data."
 

Pricing and Cost Advice

"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."
"The pricing is higher than other solutions, but with such good features, I think it's worth it."
"Setup cost is cheap: It is free, it is user-friendly, and it is fast."
"It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."
"While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."
"Luckily, we come under a large federal agency, and before the pandemic, they signed a large enterprise license agreement. It worked out great and to our advantage because we are a small organization. We got a 300 gig license, and we just did not have the buying power to be able to get products cheaply. Because we all partnered together under the agency umbrella, we were able to get Splunk Enterprise Security, UBA, and ITSI for cheap. This was good considering the fact that some of these premium apps require a minimum number of users, and we do not have the number of people needed to even justify buying it."
"It's a yearly subscription."
"Pricing is pretty fair."
"Licensing is a yearly, one-time cost."
"I believe that Splunk Enterprise Security is worth the price, but it is expensive."
