Deploy SAV for Mac on modern macOS

Hello,

 

I have some questions about enterprise product - Sophos Antivirus for Mac OS X 9.7.8.

1. Is it optimized for 64-bit compatibility on modern macOS version?

2. Is there any updated version of guide (it is dated to 2014) to understand all deployment possibilities?

3. Is there any System Lockdown for macOS available with SAV for Mac and Sophos Central?

 

Thanks

Piotr
