Overview

EchoMark is a forensic watermarking platform for sensitive emails, documents, files, and images. It embeds individualized invisible watermarks so organizations and individuals can trace leaks back to the source after content is shared.

The product is built around two main sharing paths: a web-based SecureView flow for files and attachments, and email workflows that can integrate with Exchange or Google Workspace for automatic marking. EchoMark also provides investigation tools for uploading leaked content and matching it against marked copies.

Core capabilities

Individualized invisible watermarking

Automatically applies individualized invisible watermarks to email, documents, and images so each recipient gets a traceable copy.

Email and workspace integrations

Lets organizations share marked email directly from Outlook and Gmail through Exchange and Google Workspace integrations.

Secure file sharing with access controls

Uses SecureView links to share files without relying on traditional attachments, with options to control downloads and copy/paste.

Viewing analytics and audit signals

Provides analytics on file views and recipient activity, including when a file was viewed and how long it was open.

Leak tracing and investigation tools

Supports leak investigations by comparing leaked content such as screenshots, photos, printouts, or email fragments against marked copies.

Recipient cues and visible markings

Includes visible footnotes or recipient cues in some flows to make intended recipients and traceability clear.

Where it fits

Private email sharing
Mark sensitive email before it is sent, so each recipient’s copy can be traced if the message is forwarded, screenshotted, photographed, or leaked another way.
Controlled document distribution
Share documents through SecureView instead of ordinary attachments when you need view tracking, download controls, and recipient-specific copies.
Image leak tracing
Protect images and other visual assets with invisible, individualized watermarks to help identify the source of a leak.
Team workflows in existing tools
Use the web app or Exchange and Google Workspace integrations to apply watermarks without adding a separate client application to the sender’s workflow.
Leak investigation and remediation
Investigate a suspected leak by uploading the leaked content, then compare it with marked copies to identify the likely source.
