EchoMark is an information-security company that embeds unique, invisible forensic watermarks — different for every recipient — into emails, documents, images, screen captures, and file-share links, so that when internal information leaks the exposed copy can be traced back to the individual it was released to. Products include EchoMark Screen (screenshot/photo watermarking), watermarked email communications with AI rephrasing, secure File Share, and Chroma (invisible) and Luma (print-resistant) image watermarking. The EchoMark API lets organizations embed forensic watermarking and automate leak detection across their own applications and workflows, with API clients created self-service in the EchoMark web application.
