2. Why Choose Wazuh?

• Fully open‑source, community‑driven: One of the few SIEM platforms that remains fully open‑source and actively maintained. There is no core license constraint, allowing on‑premise or cloud deployment without vendor lock-in.

• Vendor‑independent and customizable: Organizations retain full control—Wazuh can be tailored to bespoke operational needs without ongoing API fees.

3. Flexible Integration Options

Wazuh supports various integration approaches to expand its capabilities:

• Elastic Stack / OpenSearch / Splunk: For building visualization dashboards, compliance reporting, and advanced log analytics.

• Threat Intelligence (CTI) Module: Automatically ingests IoCs from external sources such as VirusTotal, MISP, or Criminal IP to enhance detection.

• OpenCTI Integration via API: Seamlessly connect Wazuh to OpenCTI using GraphQL connectors for real-time threat intel ingestion.

• Alert Routing and Workflow Automation: Use Wazuh Integrator for sending alerts to Slack, PagerDuty, Telegram, JIRA, or orchestrating workflows via platforms like Shuffle.

4. Extensive Rules & Real‑World Use Cases

• Thousands of built‑in rules: Wazuh ships with over 3,000 default rules and decoders. Users may create custom rules tailored to their environment.

• Severity levels: Alerts are categorized by severity, enabling SOC teams to prioritize incidents systematically.

• Diverse cybersecurity use cases: Detection includes PowerShell misuse, file integrity violations, patching failures, rootkits, privilege escalation, SSH brute force, malware execution, ransomware activity, and more.

• Custom rule creation & Active Response: Administrators can author decoders and rules for internal logging standards and configure active response actions—such as blocking IPs or restarting services upon detection.

5. Why This Blog Is Unique

Existing documentation on Wazuh integrations is fragmented across forums, personal blogs, and Reddit posts, lacking structure and practical guidance. This blog consolidates all verified integrations (e.g., SOCRadar, OpenCTI, Telegram), offers step-by-step deployment guides, and shares real-world implementation lessons learned—saving time and avoiding common pitfalls.
