We are running Citrix for our VDI environment, which is similiar to what Horizon is. No issues with deploying MA to the master image and all the other products. I would really advise to use MOVE instead of VSE as it really takes the burden of having an client-side viruscanner installed. We've actually never used VSE on our VDI's only MOVE.
Does the move need its own server or is a virtual appliance installed in the hypervisor
The agentless version of MOVE uses an virtual applicance on the hypervisor.
The old version of MOVE that was agent based, yes, used actual MOVE servers to do the scanning.
Are you DoD? If so PM me and can trade emails to discuss more if you'd like.
Ahhh that makes sense on the agent and agentless then. I would image the virtual appliance is the way to go.
Added u as a friend, about to PM you
