A secure, remote support platform allows secure, remote device support with an edge device (101) and a trusted intermediary server resource (“trusted server”). The trusted server (113) is an endpoint for secure connections with a support application used by a remote technician and with the edge device. The secure connections carry messages with inputs, data requests, and feedback. Messages between the trusted server and support edge device are secured in a manner that allows each endpoint to validate the messages. The remote technician controls the edge device to assesses a target device connected to the edge device. The edge device presents emulated peripheral devices to the target device while capturing the target device desktop with a camera or presents remotely controlled peripherals and returns screen captures or updates of the desktop from the target device.
