Hi, Based on Fortiguard Web Web Filtering URL Lookup & Submission,dropbox.com belongs to Category: File Sharing and Storage Have you tried to block dropbox using Application Control?(see the attached file) Don' t forget to apply App Control profile to FW Policy wish you want to block dropbox apps. regards
