We are currently using Sophos Endpoint Security and Control 10.6 on 6000 machines on one domain. Do I need to consider that when designing a deployment of Safeguard Encryption, or can I ignore the Sophos AV clients? I guess I'm thinking if they could…

Where can i get Safeguard Encryption trial download link and if possible Extended Trial License for the same ?

I see Kaspersky, Symantec, McAfee, F-secure and Trend Micro have been tested. Is anyone using AVG Cloud Care or Bitdefender with Safeguard? I have an upcoming installation and am trying to avoid a train wreck. Thanks
