Wazuh
Wazuh provides host-based and centralized security monitoring capabilities for Linux fleets.
It is interesting because it gathers several operational-security concerns into one platform: event collection, rule evaluation, file integrity monitoring, and incident-oriented visibility.
Why it matters
- Correlates endpoint and log events into actionable alerts.
- Adds file integrity monitoring and policy/compliance checks.
- Supports SOC-style workflows in self-hosted environments.
Where it fits
Wazuh fits organizations that need stronger centralized security operations than simple host-level hardening tools provide, but still want an open and self-hosted operational model.
Operational notes
- Define alert severity and triage ownership early.
- Tune default rules to reduce alert fatigue.
- Integrate with broader observability and incident response tooling.
Design cautions
- Security monitoring creates work as well as visibility. Ownership and triage discipline matter as much as deployment.
- Default rules are a starting point, not a finished security posture.
- The platform is most useful when detection logic and response procedures evolve together.
