Attaching.
The moment a PDF enters an email attachment, it is out of your control forever. Learn the architecture of secure sharing.
The Anatomy of a Leak
Most data leaks are not malicious hacks. They are benign errors. An employee forwards a pricing sheet to a "friend in the industry," or a prospect uploads your pitch deck to a public ChatGPT instance to summarize it.
- The Password Protected PDF Useless. The password is almost always sent in the same email thread, and once unlocked, the file can be re-saved without one.
