## What does EchoMark do?

EchoMark provides information leak prevention technology through invisible watermarking embedded in documents and email content. The company addresses the problem of private information leaks that occur when sensitive content is shared outside protected systems through email, documents, printouts, or screenshots. Their watermarking technology enables organizations to trace the source of leaked information, even when captured via cell phone pictures or other analog methods.

The platform embeds unique, invisible watermarks into document and message content, allowing organizations to identify the source of leaks when confidential information is shared externally. This approach addresses what the company refers to as the "analog hole" - the vulnerability that exists when people need to share information outside secure sandboxes to perform their work. The watermarks persist across various formats including printed documents and photographs.

EchoMark's solution functions as both a leak detection and deterrent mechanism. By providing traceability for leaked content, the technology aims to rebuild trust within organizations and encourage responsible stewardship of private information. The company positions its offering as covering the "last mile of information security" for organizations that need to enable collaboration and information sharing while maintaining security controls.

The platform targets organizations concerned with insider threats and information leakage, including government agencies and enterprises that handle confidential information. EchoMark's approach allows teams to share information necessary for their work while providing organizations with the ability to investigate and trace leaks when they occur.
