Exabeam
- +Among the strongest genuine UEBA implementations available
- +The LogRhythm merger brings a mature self-hosted heritage
- +Timeline-based investigation model is well suited to insider threat work
- −Post-merger product line is still consolidating — clarify which platform you are buying
- −Pricing model varies by product and is harder to forecast than per-agent
Best for Organisations where insider threat and account compromise are the priority
Watch out Establish clearly whether you are buying Exabeam or LogRhythm lineage, and its roadmap
Security Onion
- +Free and open source with excellent network security monitoring depth
- +Bundles Suricata, Zeek and full packet capture in one distribution
- +Widely used for training, research and incident response work
- −Network-focused — endpoint and identity coverage is comparatively thin
- −No commercial support unless purchased separately from the project
Best for Teams prioritising network visibility and detection engineering practice
Watch out Not a full enterprise SIEM replacement on its own — plan the endpoint layer separately
