Wazuh is an open-source security platform that acts like a central watchdog for IT environments. It collects data from servers, endpoints, cloud systems, and containers, then analyzes that information to detect threats, vulnerabilities, and unusual behavior. By monitoring logs, file changes, and system activity, it helps organizations stay aware of security risks and compliance requirements. Paired with tools like Elasticsearch and Kibana, Wazuh provides a searchable database and visual dashboards, making it easier to investigate incidents and maintain oversight. In essence, it’s a flexible and cost-effective alternative to commercial SIEM solutions that strengthens security visibility and response.
