In an enterprise, it can be extremely difficult to ensure your permissions are what you want them to be: that people can share things easily with the right groups, but also that sensitive data is not inadvertently exposed. Dropbox in particular excels at sharing documents with others outside your company, but that is also where there is obviously the most risk.
Currently, I find Dropbox's enterprise permissions management tools pretty difficult to use. There are loads of options and it's too easy to get something "wrong" if you inadvertently miss checking the right checkbox. It's not hard for me to see how AI tools could help improve this situation, and especially to provide additional capabilities in the DLP (data loss prevention) space that would make it easier to detect misconfigured access.
