It is one of the things that separates it from other tooling, and if not, it is the most scalable solution out there.

Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.

For any future enhancements or features, such as MLTK and SOAR platform integration, we need more visibility, training, and certification for the skilled professionals who are working.

The pricing for Exabeam Fusion SIEM is not cost prohibitive, but it was a little more than I initially thought.

They nearly always bill it in dollars, so if it can be billed in our currency, that would be helpful and fixed in our currency.
Manager, Customer Success at Coltek Business Soltuions
My experience with pricing, setup cost, and licensing shows that while it is a little on the higher side, since it is part of a package for all Microsoft products, I feel it is a better choice comparatively than other SIEMs in the market.

Enterprise Account Manager South at a outsourcing company with 201-500 employees
Advanced analytics have transformed our threat detection and streamlined incident investigations
I would appreciate seeing additional dashboards in Exabeam Fusion SIEM or perhaps more options or the ability to customize them further. While we can customize them currently, there may be additional options available. I value the outcomes navigator because it matches the log piece to the use cases, which is helpful. The correlation rules are excellent. I am interested in whether there are additional threat intelligence feeds available that we could use, whether we can integrate our own, or if we could ingest different ones.
Simon Johnston - PeerSpot reviewer
Manager, Customer Success at Coltek Business Soltuions
Simple antivirus solution integrates well but could improve pricing and currency options
I don't really have experience working with these solutions. I promote them for our clients, but I don't work with them. I can't share my experience with these tools as I make assumptions about that. For both Adlumin and CrowdStrike, both confirm that they're scalable and enterprise-ready and all those kinds of things. We haven't had any specific problem with either of those. We just have a preference for which one we would prefer. If somebody says they want to use a different one from the one that we prefer, then we have to find reasons why they aren't. But scalability is not one of the reasons that one is better over the other. I don't really have advice for people that are looking into using Sentinel; just do your research across what is available. On a scale of one to ten, I rate Sentinel a seven.
Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.
