What is Egress?

Egress provides intelligent email security that combines adaptive encryption with AI-powered risk detection. Rather than applying blanket encryption rules, Egress analyzes each email's content, recipients, and context to dynamically determine the right level of protection. From automatic TLS to full end-to-end encryption. Now part of KnowBe4, Egress signs BAAs for HIPAA compliance and is widely used in healthcare, legal, and financial services.
