UTMStack

UTMStack is an open-source XDR platform that unifies threat detection, response, and compliance in one system. Built on a SIEM core that correlates events, threat intelligence, and malware patterns in real time — before data is indexed — it brings together log management, XDR, SOAR, threat intelligence, vulnerability scanning, and compliance reporting, so teams can monitor, investigate, and respond from a single console instead of stitching together separate tools. UTMStack is EDR-agnostic.

Pros

    Fluency SIEM

    Fluency is an AI-centric SIEM that turns security activity into prioritized cases, evidence-backed answers, and a clearer plan for running security operations. It combines a powerful SIEM foundation with the ability to analyze, forecast, and compare across the work of analysts, security leaders, and MSSPs. Fluency’s user and entity behavior analytics (UEBA), behavioral change detection, correlation, clustering, and risk scoring bring related activity together and prioritize the issues that need attention. Large volumes of events become fewer, more meaningful cases.
