US Patent 11019031 Client software connection inspection and access control

A controlled content system for providing a controlled and contained environment that is remotely accessible is disclosed. A third party app on the end user device is modified to allow certain sites and services to be mediated in a mid-link server. The app uses policies to know when to access the mid-link server for the controlled and contained environment. Policies can specify the type of processing performed on the mid-link server. Some embodiments support the app selectively using the mid-link server for mediated sites and services.
