As of version E84.20 SandBlast Agent fully supports CITRIX XenDesktop (PVS & MCS).
The versions that were officially certified are: 7.6, 7.15, 7.18, and 7 build 1912 (latest version), and supports both Persistent and Non-Persistent deployments.
Nonetheless, any version higher than CITRIX XenDesktop 7.6 should be supported and should function properly.
The solution is in GA quality and is included in all package types, for more information - please review this guide Endpoint Security VDI E83.10 Administration Guide.
