It is considered to be a best practice to use the Per-App Tunnel component as it provides the most functionality with easier installation and maintenance. Per-App Tunnel uses the native platform (Apple, Google, Microsoft) APIs to provide a seamless experience for users. The Per-App Tunnel provides most of the same functionality of the Proxy component without the need for additional configuration that Proxy requires.

The Per App Tunnel component and VMware Tunnel apps for iOS, Android, Windows Desktop, and macOS allow both internal and public applications to access corporate resources that reside in your secure internal network. They allow this functionality using per app tunneling capabilities. Per app tunneling lets certain applications access internal resources on an app-by-app basis. This restriction means that you can enable some apps to access internal resources while you leave others unable to communicate with your back-end systems.
