nPro
- +ClickHouse backend rather than Elasticsearch — materially less tuning to operate
- +Flat per-agent licensing means log volume never affects the bill
- +Network monitoring included rather than sold as a separate product
- −Integration and app ecosystem is small compared with Splunk or Elastic
- −Behavioural analytics in development — not comparable to Securonix or Exabeam today
Best for Regulated organisations needing full residency control without operating an Elastic stack
Watch out No SaaS option; you need a Linux server somebody patches and monitors
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
