Zertificon’s white paper defines true end-to-end email encryption (E2EE) as device-level encryption at the sender and decryption at the recipient, ensuring only the intended recipient accesses decryption keys—unlike vendor solutions treating businesses as one “end.” Zertificon software revolutionizes enterprise implementation through its Z1 SecureMail Gateway and End2End extension, seamlessly handling S/MIME, OpenPGP, and password encryption as a proxy for internal/external routes. It automates key management, integrates anti-virus/DLP tools between encryption steps, maintains data sovereignty, and enables compliant, workflow-friendly secure communications across on-premises or cloud infrastructures.
