Sophos Endpoint Security
For Sophos Endpoint Security, a firewall exclusion needs to be added for 127.0.0.1 (localhost) port 5811/5812. While no issues will be reported by the Sophos Endpoint Security software, the way this software works causes conflicts with the Agent.
Microsoft Defender
For Microsoft Defender, you should consider adding an exclusion or disabling the Network Protection feature when experiencing slow downloads from the Application Workspace System. This occurs when domains (that the Recast Software zone is running on) has a low reputation. For more information regarding the Network Protection feature and how to change the configuration, see Microsoft documentation.
