How to block tagged files being transfered to Dropbox?

What is the best way to block files tagged in DLP from being transferred through Dropbox? I tried using a Network Communication Protection rule and defined the application Dropbox which did work. However, when a tagged file was copied to Dropbox a event was triggered every couple of seconds when it tried to sync until the file was deleted from Dropbox. Is there a way to block it from being put in the C:\Users\user\Dropbox folder?


We are using DLP 9.1

    Hi ruckelj,


    Due to the way Dropbox works the NCPR is the best way to block tagged file being uploaded to DropBox and there's no rule available to block local file transfers. Do you see multiple events in the DLP Monitor?
