>>>Network Filtering applications interferenceNetwork filtering applications such as Little Snitch or VPN software running in tandem with Sophos Home or other software with network filtering capabilities, may trigger errors or not work at all. If you experience issues with Sophos Home or another network based program, we recommend either disabling or removing the other program and re-testing functionality.
