This post presents Wazuh CLI, an open-source command-line tool that simplifies managing and automating Wazuh SIEM/XDR operations for cybersecurity monitoring and incident response.
OpenCTI can expose shared data through different native feeds, including Live streams, TAXII collections, and CSV feeds. For this integration, I chose a TAXII collection because it exposes STIX 2.1 bundles through a standard API and provides a pagination model that is straightforward to automate.
By connecting Wazuh to Claude Desktop using MCP (Model Context Protocol), you can talk to your SIEM like you’d talk to a colleague. No complex queries. No dashboard hopping. Just ask, and get answers.
A common mistake in monitoring design is collecting too many metrics without understanding their purpose. More data does not mean better monitoring. It often means more noise. Effective monitoring focuses on a small number of high-value signals that clearly indicate when something is wrong.
One week after Copy Fail (CVE-2026-31431), V4bel dropped Dirty Frag – CVE-2026-43284 and CVE-2026-43500. Same authencesn decrypt sink. Completely different code path.
How we unified security monitoring and infrastructure observability into a single pane of glass – without replacing a single tool.
Wazuh is highly customizable, which allows us to build our own case management and remote command capabilities without requiring any additional agents.
To demonstrate USB activity monitoring and potential data exfiltration detection using Wazuh, a dedicated Windows-based lab environment was prepared.
