Harden National Defense with Forensic Watermarks

EchoMark’s invisible forensic watermarks provide a sophisticated and effective way to deter and remediate leaks of sensitive defense data while ensuring information is seamlessly shared with those who need to know.

Powerful, Seamless Deterrence and Detection

By embedding forensic watermarks in classified documents, operational communications, and sensitive negotiations, EchoMark creates a sense of accountability among data handlers that effectively deters leaks while providing a robust way to identify sources if sensitive data leaks.

Confidential

Increase Accountability

With visible footnotes at the bottom of messages and documents indicating their intended recipients, EchoMark ensures that sensitive content remains exclusively within the intended circle by notifying recipients that the information is directed at and traceable to them.

Identification

Identification and Chain of Custody

EchoMark’s unique signatures embedded invisibly in sensitive communications and documents enable the means to quickly identify leak sources and their entire chain of custody. EchoMark’s easy-to-use yet robust investigative reports can be used as evidence for security teams and investigators, who can then take appropriate action against responsible parties.

Automatic, Silent, Secure

EchoMark’s Forensic Watermarks require no client software, preserving the natural flow of communication without disrupting familiar interactions. EchoMark can be deployed on the backend in minutes, controlled through policy set by admins, and operate within your private or air-gapped environment.

Upload the leaked artifact to EchoMark's investigation tool to identify whose copy leaked, with a confidence score and chain of custody.

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.

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
