SIEM software supports security teams working with event data, detections, and alerts. Compare custom detection rules and real-time alerting, along with data retention and deployment, to assess how the entries differ operationally. Query language and free ingestion limit offer more points of comparison; free-plan availability and paid-from pricing add plan context. The ranking begins with nano SIEM and Wazuh, followed by Vigil and Elastic Security. Seceon Open Threat Management, Sumo Logic, CrowdStrike Falcon Surface, and Rapid7 Surface Command are also among the early entries. Consider the detection, data-handling, and deployment needs you have, then weigh them against the listed criteria.

23 SIEM software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
