VERDICT

Should I use Wazuh?

Wazuh is a free and open source security platform that unifies XDR and SIEM protection for endpoints and cloud workloads. - wazuh.com

Depends. Buy it if you have security engineers to deploy, tune, and patch an open-source SIEM — nothing matches the $0 price. Avoid it if you need turnkey detection or lack dedicated security staff; it will sit misconfigured.

Confidence

Medium. Based on 25+ public sources: Reddit threads, G2, case studies, CVE databases, and pricing trackers.

  • Buyers needing vendor SLAs on the free tier
  • Orgs that cannot patch infrastructure quickly after CVEs

Gotchas - check before you buy

high

Little works out of the box; expect significant setup before useful detections appear

high

Critical RCEs in 2025-2026 mean slow patching of your manager is dangerous

medium

Free license, not free labor: infra, staffing, and tuning are the real total cost

medium

False alerts are a documented pain point; plan continuous rule tuning
