Overview

Wazuh is a free and open-source security platform that unifies SIEM and XDR capabilities for threat prevention, detection, and response across on-premises, virtualized, containerized, and cloud environments. It deploys lightweight agents to collect security data from endpoints, then centralizes analysis, correlation, and alerting on a manager node. Wazuh includes File Integrity Monitoring (FIM), vulnerability detection via CVE correlation, Security Configuration Assessment (SCA) against CIS benchmarks, rootkit and malware detection, active response, and full cloud-native integrations with AWS, Azure, and Google Cloud. It was named the 2026 Cybersecurity Stars Award winner for Best Cloud Security Platform.

Primary Use Cases

✔ Centralizing and correlating log data from endpoints, servers, cloud services, and network devices for real-time security event monitoring and alerting.

✔ File Integrity Monitoring (FIM) to detect unauthorized changes to critical files, directories, and Windows Registry keys across monitored endpoints.

✔ Vulnerability detection by correlating installed software inventory on monitored endpoints with CVE databases to surface known exploitable flaws.

Frequently Asked Questions

Yes. Wazuh is free and open-source software licensed under GPL v2, with no licensing fees, no per-agent costs, and no data ingestion limits, making it a popular alternative to commercial SIEM platforms.

As of September 2026, the current stable release is Wazuh 4.14.x, with Wazuh 5.0 in beta and expected to reach general availability later in 2026. The project publishes regular patch and minor releases on its official GitHub repository.

Yes. Wazuh provides native integrations with AWS, Microsoft Azure, and Google Cloud Platform, allowing it to collect and analyze cloud service logs, monitor configuration changes, and detect threats across cloud infrastructure alongside on-premises assets.

Wazuh is fully open-source under GPL v2 with no licensing costs and no data ingestion limits, whereas Splunk operates on a commercial license and Elastic uses an open-core model (Elastic License / SSPL) with usage-based pricing tiers. Wazuh also ships with built-in HIDS, FIM, SCA, and vulnerability detection out of the box rather than requiring separate modules.

Yes. Wazuh has native Docker and Kubernetes integrations that monitor container behavior, images, volumes, and orchestration events, and it supports agentless monitoring for environments where installing an agent is not practical. Security events from containers are correlated with host and cloud telemetry in the same SIEM pipeline.
