OpenText ArcSight Enterprise Security Manager (ESM)
ArcSight Enterprise Security Manager (ESM) is a comprehensive threat detection, analysis, triage, and compliance management SIEM platform that dramatically reduces the time to mitigate cyber-security threats.
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.
