Wazuh is a free, open-source security information and event management (SIEM) and extended detection and response (XDR) platform. It collects, analyzes, and correlates security data across endpoints, cloud workloads, and containers. Unlike commercial SIEMs (Splunk, IBM QRadar), Wazuh is completely free — organizations run it on their own infrastructure.
