We love that you can get a sense for what is going on in an organization by just looking at who is sharing documents internally! The interface isn't as intuitive as it could be. At this time we cannot see any way to filter out internal only users/groups. I would also like there to be more organization options. What we do now is pretty straight forward, but sometimes I'd like to create custom groups or add sub-groups to one of the existing ones, to make it easier to find things later. This helps with our compliance audit process. As mentioned above, using GroupSense has helped us streamline our compliance audit process. It shows us which employees have been in contact with an external party, and who has knowledge of particular files or folders.
