Sophos tries to contact a server on my company VPN

Periodically my outbound firewall LittleSnitch tells me that Sophos AV for Mac is trying to contact the IP at 10.0.0.98. This would be the address of the DNS nameserver that my company operates over a VPN.

Why would Sophos be trying to contact this server?

  • Just to clarify: Live Protection uses custom DNS requests to contact Sophos regarding suspicious files.  The DNS lookup request is actually transferring the data to be examined to the Live Protection server; the response to this request contains the "good/bad" verdict.  This data does not contain any actual content from your computer, but contains a hash of the flagged file, to be compared to known hashes in the Live Protection system.  For it to work, Little Snitch has to let these queries go through.

    If you have auto-update and live protection disabled, Little Snitch should not be triggering any Sophos-related connection attempts.
