While sharing PDFs across the team, organization, or clients, a lot more protection is needed than just a password. With AI advancements, it is now possible to share a PDF securely.

Some platforms like RDocs offer superior protection to PDF files where the document owner gets to have a kind of remote control. What that means is that the sender or document owner can restrict access by domain, IP, or geography, and restrict access to print, screen capture, or share without consent. Most importantly, RDocs offers the ability to kill (unsend) a PDF even after it has been shared and viewed and identify data leakers.
