The standard in forensic watermarking

The only platform that traces real-world leaks — silently, automatically, and invisibly, all without disrupting how your team works. Mark content across emails, documents, images, and screens.

Watermarking capabilities

From what EchoMark can watermark to how it survives real-world leaks and deploys into your stack.

Mark sensitive information to make it traceable

Your organization's sensitive content can be invisibly and individually watermarked per recipient, without changing the reading experience or workflows. Visible watermarks can be optionally added.

Watermarks that survive real-world leaks

EchoMark's marks are engineered to survive common exfiltration methods — from photos to screenshots to physical printouts to re-typed text.

Marks survive the following:
Photos of screens
Black-and-white print-outs
Copy/paste or re-typing on another device
Screenshots
Partial fragments of content
Format conversion & re-compression

Identify the source of information leaks

Submit the leaked content — a photo, a screenshot, a reworded excerpt — and EchoMark produces a forensic report identifying the source, often in minutes.

Investigation report includes
Leak source
Confidence score of leak source
Watermark type detected
Originals and marked copies analyzed
Chain-of-custody reporting available upon request

EchoMark Screen

Make every display traceable, across all apps and file types

Screen-based leaks bypass traditional controls — DLP can't stop a phone photo, and IRM can't tell you who took it. A proprietary algorithm overlays a randomized translucent pattern over whatever is on screen, so when sensitive information escapes you can still identify the source.

Details
Covers all applications and file types
Invisible marks survive screenshots and photos
Optional visible watermarks to deter leaks
Supports IT-managed Windows endpoints with centralized deployment
Supports virtual and remote desktops
For shared logins, can provide attribution via device ID + session timestamp
