Wazuh — open source XDR/SIEM
Wazuh is an open source platform that combines endpoint detection and response with security information and event management in a single deployment. The appeal here is practical: one toolchain for visibility across servers, workstations, and cloud infrastructure, with no licensing friction. For security teams evaluating their monitoring stack, the trade-off is familiar—you get flexibility and no per-seat costs, but you're responsible for running and maintaining the infrastructure yourself. The real shift is whether your org has moved far enough into hybrid and cloud environments that a unified view across both endpoints and cloud actually solves a problem you currently patch over with multiple tools. If you're still running everything on-premise or still treating cloud as separate, it's less urgent.
