App wrapping is the process of applying a management layer to a mobile app without requiring any changes to the underlying application.
App wrapping allows a mobile application management administrator to set specific policy elements that can be applied to an application or group of applications. Policy elements can include such things as whether or not user authentication is required for a specific app, whether or not data associated with the app can be stored on the device and whether or not specific APIs such as copy and paste or file sharing will be allowed.
In the enterprise, app wrapping allows an administrator to take an application, associate extra security and management features with it and re-deploy it as a single containerized program in an enterprise app store.
