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. When suspicious behavior is detected, the platform can automatically block malicious IPs, disable compromised user accounts, kill unauthorized applications, or detach unmanaged USB devices via its integrated USB Defender. This immediate response capability significantly reduces the window of vulnerability during a cyber-attack. To ensure deep visibility, SEM features built-in File Integrity Monitoring (FIM), allowing you to track sensitive file changes, deletions, and registry modifications. The platform also streamlines audit preparation with hundreds of pre-built, out-of-the-box compliance reports for major regulatory frameworks, including HIPAA, PCI DSS, SOX, ISO, DISA STIGs, and FISMA. With its intuitive text-based searching and integrated threat intelligence feed, SEM normalizes disparate log data into a readable format. This enables faster forensic analysis and historical searching, helping your team identify patterns from known bad actors and strengthen your overall security posture. Whether you are managing internal threats or external breaches, SolarWinds SEM provides the essential tools to detect, respond, and report with confidence. For organizations seeking tailored security control, SEM is highly effective as a standalone SIEM tool, providing dedicated log management and incident response. However, for those looking to eliminate silos between security and IT operations, SEM can also function as a core component of SolarWinds Observability.
