It's part of Sophos Central Server Core Agent and is available with any Server Protection license in Sophos Central. Currently, SATC with Sophos Server Protection only supports Windows Remote Desktop Services.You must download the Windows Server installer from Sophos Central. The installers that you can download would depend on the licenses you have. 

Sophos Firewall controls those authenticated users using a session-based approach via an identity-based firewall rule providing more granular access controls per user group.

    command: - reg add "HKLM\Software\Sophos\Sophos Network Threat Protection\Application" /v SatcPendDurationMs /t REG_DWORD /d 300 



    NOTE: We are updating the pend duration only when there is network latency
