Open-source XDR and SIEM platform with host-based intrusion detection, file integrity monitoring, and log analysis.

9.3/10
Overall
Features9.6/10
Ease of Use9.1/10
Value9.0/10
Standout feature

Wazuh’s centrally managed rule engine supports decoders and detection rules that generate correlated alerts from host logs.

Wazuh runs an agent on each monitored host and sends structured events to the manager, where it evaluates decoders and detection rules. File integrity monitoring and system inventory support baseline visibility, while built-in compliance checks map host state to hardening guidance. Alert outputs can be routed to downstream systems and correlated with other telemetry when Wazuh events are ingested into the same monitoring pipeline.

A key tradeoff is that false positive reduction depends on rule tuning and workload-aware threshold settings, which requires detection engineering time. Wazuh fits best for teams that already operate a host telemetry pipeline and want centralized governance for agent enrollment, policy distribution, and alert routing rather than a purely point tool.

Pros
  • +Rule-based detection engine with decoders for structured log normalization
  • +Centralized agent management with RBAC and audit logging
  • +File integrity monitoring with configurable paths and alert thresholds
  • +SIEM-style event forwarding for correlation in existing pipelines

9.0/10
Overall
Features9.1/10
Ease of Use8.8/10
Value9.0/10
Standout feature

Active response ties detections to automated containment actions on monitored hosts.

OSSEC uses an agent model where monitored hosts send events to a manager for rule evaluation and alert generation. Core capabilities include file integrity monitoring, log inspection, and active response actions that can be triggered based on detections.
