Frequently asked questions
Is Wazuh really free, and what does it actually cost to run?
Wazuh is free and open source, so there is no license fee and no vendor lock-in. The real cost is not licensing. It is having someone to tune the rules and act on what the platform surfaces, plus the infrastructure to run the server and store log data. Open-source security tooling is free to license and expensive to ignore, which is the trade you are actually making.
What can Wazuh do that a commercial SIEM does?
Wazuh provides threat detection, log analysis, file integrity monitoring and compliance reporting, the capabilities usually sold as expensive enterprise SIEM. It correlates and analyzes log data from multiple sources to detect threats and vulnerabilities, extends protection to endpoints and cloud workloads as an XDR platform, and automates incident response through active responses. Integrated threat intelligence feeds strengthen the detection side.
How are the Wazuh agent, server and dashboard related?
The agent is deployed on endpoints and cloud workloads, where it collects and analyzes log data and sends it to the server. The server processes what arrives, applies Wazuh rules to correlate events and detect anomalies, and generates alerts. The dashboard is the interface on top, giving real-time visibility into events, alerts and system status, with customizable widgets and search for drilling into specific incidents.
What is involved in deploying Wazuh?
Install the indexer, server and dashboard, then deploy agents on the endpoints you want to monitor. Many teams run the stack in Docker containers for easier management and upgrades. Set firewall rules first, so the server is reachable only from the networks and agents that should be talking to it. Then configure agents to collect the right logs and test that detection actually fires as expected.
What are the hardest parts of running Wazuh?
Configuring agents and managing rules is genuinely complex and needs a real understanding of the platform. Scaling to large cloud environments takes planning and resource allocation. Interpreting log data and customizing the dashboard often requires specialized expertise. Community documentation, configuration management tools for automating agent deployment, and regular rule review are the practical answers to most of it.
Can Wazuh help with regulatory compliance?
Yes. File integrity monitoring, security controls and reporting support compliance work, and the dashboard can be customized around requirements such as PCI DSS. Role-based access control ensures users only see the information they need, which itself matters for maintaining compliance. Alerts and notifications can be tuned to your own thresholds and triggers so the evidence reflects the controls you actually run.
Can Wazuh work alongside security tools we already have?
Yes. The Wazuh API enables integration with other security tools, so you can feed an existing SIEM, connect a ticketing system, or share threat intelligence across platforms. That flexibility is what lets Wazuh sit inside an existing security stack rather than replacing it, automating incident response workflows across the tools your team already uses instead of adding another isolated console.
