Security Feature

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.

Why Watermark Your Documents?

Watermarking creates accountability and deters unauthorized sharing

Deter Unauthorized Sharing

Visible recipient information on every page discourages leaks and unauthorized distribution of sensitive documents.

Trace Document Leaks

If a document surfaces publicly, watermarks reveal exactly who received it, enabling accountability and investigation.

Protect Intellectual Property

Safeguard proprietary information, trade secrets, and confidential materials with personalized watermarking.

How It Works

Automatic, Personalized, Tamper-Resistant

ShareDoc automatically generates unique watermarks for each viewer, embedded into the document on every page

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.
