Unroll.me is a third party app that helps you unsubscribe from email subscriptions in order to reduce the size of your inbox. The app gains access to your Google account thru OAuth, which you granted when you installed the app on your phone or tablet. Companies should add a Cloud Access Security Broker (CASB) solution to their technology stack. Its important to select a CASB that automatically looks for all apps that users have granted permission to using corporate credentials so IT managers can take proactive steps.”]
