Prevent Sophos from breaking Linewize Connect's companion mode

Updated

When Sophos is running endpoint protection on devices, it prevents the Connect extension from communicating with Connect for Windows, causing a “configuration missing” error.

To fix this issue, you must configure web control, threat protection, and decryption exclusion policies for Linewize in Sophos Central.

Before you begin

  • You must have Administrator access in Sophos Central.
  • You must be a Linewize Connect Administrator.
  • Check your Sophos Endpoint version.
