Wazuh
Open-source SIEM and XDR platform providing endpoint monitoring, log analysis, file integrity checks, and threat detection.
Technical Architecture & Overview
Wazuh combines SIEM and XDR capabilities to monitor endpoints and cloud workloads. It uses lightweight agents to collect system logs, monitor file integrity, detect rootkits, and verify compliance against CIS benchmarks.
Targeted Technical Use Cases
Centralizing security event monitoring, endpoint telemetry, and automated compliance auditing across hybrid cloud systems.
Evaluation & Trade-offs
Core Strengths
- +Combines log collection, threat detection, and File Integrity Monitoring in one agent.
- +Ships the Wazuh Indexer (an OpenSearch fork) and Wazuh Dashboard by default; can also forward alerts to third-party OpenSearch, ELK, or Splunk.
- +Supports automated active responses to isolate compromised endpoints or block malicious IPs.
Trade-Offs & Limitations
- -Cluster deployment and indexer storage require dedicated capacity planning.
- -Agent rules need initial tuning to prevent alert fatigue in noisy environments.
Defensive Security Application
Centralizing host security events, detecting unauthorized file modifications, and verifying system configuration baselines.
