When you’re evaluating SIEM software, focus on how each option handles detection, investigation, and the flow of security data. Compare custom detection rules and query language, then weigh real-time alerting, data retention, and deployment against your operating needs. Free ingestion limits and free-plan availability can help clarify what’s accessible without a paid plan; the paid-from price adds a cost point to consider. Wazuh, Elastic Security, and Vigil are among the entries to compare, alongside CrowdStrike Falcon Surface and ManageEngine Log360. Check which listed capabilities match the data volume, response workflow, and infrastructure you need to support.
