EchoMark

EchoMark enables secure, traceable sharing of information by embedding invisible, individualized watermarks into content for each recipient. It supports emails, documents, images, and on-screen content, adding marks without changing how the content looks or is read. The tool is designed for organizations handling sensitive information and seeks to deter leaks and identify sources when they occur.

The system works by watermarking content before distribution and then, if a leak is detected, the leaked artifact is uploaded to an investigation tool. EchoMark provides a confidence score and chain-of-custody documentation to support attribution and investigation workflows.

The platform offers multiple deployment options and integrates with existing security stacks. It supports cloud hosting, optional single-tenant deployment, on-premises deployment, and air-gapped environments, with compliance features and data residency options to fit security-conscious organizations.

EchoMark provides products for different content types (Email, Screen, File Share, API) and includes options for both invisible and visible marks, AI rephrasing, and per-view analytics. It emphasizes compatibility with Microsoft Exchange and Google Workspace, and lists various security and integration features.
