Wazuh SIEM

Wazuh is a free, open-source security platform that provides unified SIEM, XDR, and compliance capabilities for on-premises, cloud, and hybrid environments through a lightweight agent that collects and analyzes security events from endpoints, applications, and infrastructure. Its built-in rules and decoders detect threats including malware, rootkits, privilege escalation, and configuration violations, while its compliance modules map findings to PCI DSS, HIPAA, NIST, and other regulatory frameworks. Security teams at organizations seeking enterprise-grade security monitoring without commercial SIEM licensing costs use Wazuh for its comprehensive detection capabilities, active open-source community, and full deployment flexibility.
