We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy.

Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations. They are working on it, yet there are only five to ten very basic visualizations.

One main change I would suggest is related to the incident board: when an incident is resolved, it should not appear on the incident board. It's just a rare occurrence that we open up the incident.

One area Splunk Enterprise Security fails to improve is the pricing aspect; while the initial pricing seems fine, the licensing cost can skyrocket over time, creating trauma for organizations.

Pricing is certainly an area that could use improvement. While some vendors may offer lower prices, the value we receive here truly sets this solution apart.

Regarding pricing, Splunk Enterprise Security is on the higher side in terms of cost. It is more suitable for enterprises that can fully utilize its capabilities, and smaller organizations might find it expensive, especially when dealing with large volumes of data and licensing models.
MatthewSnyder - PeerSpot reviewer

When deploying Enterprise Security, the biggest challenge or the most amount of work that you're going to spend time on is onboarding your data and getting it into a position that allows you to search it uniformly. So applying things like the common information model is the biggest time investment that you'll have in the deployment.

I find the process for customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security to be cumbersome.

We're planning to incorporate UBA and SOAR. It would be good to have everything in one place.
