SolarWinds Security Event Manager vs. UTMStack

Security Event Manager (SEM) is a powerful, real-time Security Information and Event Management (SIEM) solution designed to act as a virtual Security Operations Center (SOC). It provides active monitoring and automated threat detection across multi-vendor network devices, servers, workstations, and applications. SEM is delivered as a downloadable virtual appliance for rapid deployment, and allows IT teams to centralize log data and enable real-time event correlation right out of the box. SEM goes beyond simple alerting by offering automated remediation actions.

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.
