RustDesk - remote access to another computer's desktop from anywhere in the world, will allow you to control it as if you were sitting right in front of it. This is a direct analog of such programs as TeamViewer, AnyDesk and Splashtop.

This is a powerful and flexible remote control tool that combines simplicity, security and customization.

The main advantage is the ability to deploy your own remote access server for secure and reliable remote desktop connection due to the lack of connection to third-party servers.
