Yes, Wazuh is 100% free and open-source — no paid tier, no license fees, no usage caps. Unlike commercial SIEMs like Splunk Enterprise or IBM QRadar that can cost $50,000–$200,000 per year, Wazuh delivers full SIEM + XDR capabilities under the GPLv2 license. In this guide, I’ll break down exactly what “free” means in Wazuh’s case, what you actually get, and where hidden costs (if any) show up.
A Free and Scalable SIEM Solution
Wazuh functions as a Security Information and Event Management (SIEM) tool. It collects and analyzes logs from multiple sources — including servers, endpoints, cloud workloads, and virtual machines — and turns raw data into actionable security insights.
Unlike many commercial SIEM solutions, Wazuh is completely free and open-source, making it accessible to both large enterprises and smaller organizations with limited budgets.
Is Wazuh Really a Real SIEM?
Yes. Wazuh is a full-featured SIEM used by thousands of organizations worldwide, including Fortune 500 companies. It covers the complete SIEM feature set: log collection, normalization, correlation, alerting, threat intelligence, and compliance reporting — plus XDR capabilities most traditional SIEMs lack.
Extended Detection and Response (XDR) Capabilities
Beyond being a SIEM, Wazuh also provides XDR features. It can detect intrusions, monitor file integrity, and identify vulnerabilities in real time. These insights allow IT and security teams to respond rapidly, significantly reducing the potential damage caused by cyberattacks.
Compliance and Monitoring
Wazuh includes built-in compliance management features that support frameworks such as PCI DSS, GDPR, HIPAA, and ISO 27001. Organizations can continuously monitor their systems and generate audit-ready reports with minimal effort.
Centralized Dashboard
One of Wazuh’s most valuable features is its modern web-based dashboard. Administrators can visualize alerts, monitor security trends, and manage the entire environment from a single interface. The dashboard integrates with Elastic Stack, providing advanced search and visualization capabilities.
Why Choose Wazuh?
Wazuh is trusted worldwide because it is open, flexible, and scalable. It can be deployed on-premises, in hybrid environments, or in the cloud. With strong community support and continuous updates, Wazuh offers organizations a reliable way to strengthen their cybersecurity posture — without the high costs of commercial tools.
❓ Frequently Asked Questions
Is Wazuh completely free?
Yes, Wazuh is 100% free under the GPLv2 open-source license. There is no paid tier, no license fee, and no limit on the number of agents, users, or logs. The entire platform — Manager, Indexer, Dashboard, and Agents — is free for commercial and personal use.
Is Wazuh a real SIEM?
Yes. Wazuh provides all standard SIEM capabilities: centralized log collection, normalization, correlation rules, real-time alerting, threat intelligence integration, and compliance reporting. It is listed in Gartner’s SIEM category and used by organizations of every size, from startups to Fortune 500 enterprises.
Is Wazuh better than Splunk?
It depends on your needs. Splunk is more mature in advanced analytics and has a larger third-party app ecosystem, but it’s extremely expensive at scale (licensing based on data volume). Wazuh delivers ~80% of Splunk’s core SIEM functionality for free, plus native XDR features (FIM, vulnerability detection, active response) that Splunk charges separately for.
Can I use Wazuh commercially?
Yes. The GPLv2 license allows commercial use without paying any fees. You can deploy Wazuh to protect your own company’s infrastructure, or offer managed Wazuh services to clients. The only restriction is that any modifications you make to Wazuh’s source code and redistribute must also be released under GPLv2.
Where are the hidden costs?
Wazuh itself has no hidden costs, but you will need to pay for: (1) the infrastructure to host the Manager and Indexer (on-prem servers or cloud VMs), (2) storage for retained logs, and (3) optionally, Wazuh Cloud or professional support from Wazuh Inc. if you want SLA-backed assistance. For most small-to-medium deployments, total cost of ownership is 10–20x lower than commercial SIEMs.
