Every outbound email is signed with your domain's cryptographic key pair. The stamp embeds sender identity, timestamp, and a hash of the email body. Recipients verify with one click — no special software needed.
Our detection engine cross-references sender behavior, email headers, and MIP (Mail Integrity Protocol) signals to flag impersonation attempts in real-time. CEO fraud, wire transfer scams, and vendor impersonation are blocked before delivery.
Every stamp generates a signed, timestamped proof that can be exported as a PDF for legal proceedings. Cryptographic chain-of-custody ensures the evidence is tamper-proof and independently verifiable.
Every feature designed for reliability at scale. No compromises.
