SDT Engine / Capability
Reverse Authentication flips the auth direction. The recipient verifies the sender, not the other way around. Stops impersonation attacks at the click.
Reverse Authentication is a new SDT Engine security primitive that addresses the gap every secure-transport vendor has historically left open: the recipient has no good way to confirm the sender is who the sender claims to be. Business Email Compromise (BEC) attacks ride exactly that gap. Reverse Authentication closes it by giving the recipient a verifiable signal that the inbound transport originated from the legitimate sender, before any data exchanges hands.
Reverse Authentication is currently the subject of a Botdoc patent filing. Technical implementation details, integration scope, and availability timeline are still being scoped for public documentation. Customers and partners interested in early access can reach out through the Dev team contact.
