Overview

With the introduction of the mini file filter driver, which is part of SafeGuard Enterprise as of version 8.10, Sophos provides regular File Encryption Engine updates that just contain improved filter drivers. These updates are provided as Windows Installer Patch files (*.msp) to allow an easy installation and deployment.
