What is SophosUI.exe?

This process is part of the Sophos Endpoint Protection suite, commonly deployed in business and enterprise environments. The UI provides access to scan results, threat notifications, policy settings, and real-time protection controls. It runs when users need to interact with their Sophos security software.

Quick Fact: SophosUI.exe typically launches on-demand when you open the Sophos interface from the system tray or start menu, rather than running constantly in the background.
