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. As these updates are cumulative, Sophos recommends using the latest version.
In this KBA you can download build version 28 of the filter driver engine. An overview of all File Encryption Engine Updates is available here.

As this package just contains new filter drivers and no other products components, this update does not change the version or build number of the installed SafeGuard Client. In the SafeGuard Management Center version 8.20, the file filter engine version of this update (184.108.40.206) is also listed in the installed features list of the Client.
