Is it possible to start VMWare Horizon Session from SPP? I could not find any information in Admin Guide.
SPP supports RDP, SSH and Telnet sessions to target assets via Safeguard for Privileged Sessions (SPS) appliance whether the assets are physical or virtual machines as long as the required ports are open.
Supported clients are listed here:
SPP initiated sessions do supports RDP connections which will route via SPS anyways therefore if the Client is using the RDP port 3389 while pointing to SPS then it should work the same way as any normal RDP connection.
Similar to Figure 217: Client - SPS - Server in the link below:
