There’s now a powerful and flexible Drive Permissions tool that reviews the sharing privileges of all files held in Google Drive. It identifies the users outside your domain with whom documents are shared and which files they are.
It allows you to track down your exposures and easily unshare
or even by individual file
Drive Permission makes it easy for administrators to understand who has access to what information and immediately change the sharing rights en-masse, allowing you to minimize risk and stay secure by effectively safeguarding your information.
