Tessian vs Proofpoint -- AI Email Security Compared

Tessian vs Proofpoint

Tessian approaches email security from the human layer perspective, uniquely combining inbound threat detection with outbound misdirected email prevention and accidental data loss protection. Its ability to detect when a user is about to send sensitive data to the wrong recipient is a capability that Proofpoint's gateway model does not natively address in the same way. Now that Tessian has been acquired by Proofpoint, its technology is being integrated into the Proofpoint platform. As a standalone comparison, Tessian fills specific human risk gaps while Proofpoint provides comprehensive end-to-end email security.

The Verdict

Choose Tessian if preventing misdirected emails and accidental data loss is a critical requirement that your current email security does not address, or if you want behavioral AI coaching for users. Choose Proofpoint if you need a comprehensive, enterprise-grade email security platform with full threat protection, archiving, and compliance. Note that Tessian's technology is being absorbed into Proofpoint, so its standalone future is uncertain.
