IGEL OS offers the ability to observe the endpoint device via shadowing through the IGEL Virtual Network Computing (VNC) Viewer in the Universal Management Suite (UMS) or another VNC client (e.g. TightVNC), see Shadowing - Observe IGEL OS Desktop via VNC. The shadowing of IGEL OS 12 devices through the UMS is always via Unified Protocol, i.e. communication is always encrypted. This article shows the settings for configuring the VNC access to your devices.

Menu path: System > Remote Access > Shadow
