Dynamic Watermarking
Every page, personalized. Every viewer, accountable. Protect sensitive documents with automatic watermarks that embed recipient information on every page.
Meet Emily—she stopped the leaks
Emily is General Counsel at a pre-IPO tech company. Someone leaked their S-1 draft to a tech blog before the filing. The company scrambled to identify the source. Email logs were inconclusive. The damage was done.
After the incident, Emily implemented ShareDoc's dynamic watermarking. Now every page of every sensitive document displays the recipient's email, timestamp, and access location. The visible accountability changed behavior overnight.
No more leaks. No more panic. Just peace of mind.

Watermarking Features
Important: Watermarks and Analytics
Dynamic watermarking requires our analytics infrastructure to generate personalized watermarks for each viewer. If you enable end-to-end encryption (E2EE) via custom onboarding, watermarking and other engagement features (heatmaps, time tracking) will not be available, as we cannot access document content to apply watermarks in a zero-knowledge architecture.
