Invoice fraud & BEC detection for Gmail. Flags spoofed domains, changed bank details & fake urgency — email analysis runs locally.

CypherSeal is invoice-fraud and business email compromise (BEC) detection for Gmail. It catches the spoofed domains, changed bank details, and fake-urgency tactics behind wire fraud, vendor-payment scams, and email fraud — reading each email and invoice locally in your browser, before you act on it. Gmail checks whether an email is spam. It doesn't check whether the invoice inside is real. CypherSeal reads it first. BEC isn't a flashy attack. It's one wrong invoice on a Tuesday morning — a vendor's bank details quietly changed, a domain off by one letter, a "process this today" that skips your normal review. CypherSeal catches it at the moment it's being read. ➤ The 5 questions your inbox can't answer - Who really sent this? — look-alike domains, display-name tricks, reply-to mismatches - Where's the money going? — remembers payment details, flags when they change - Why the rush? — detects pressure tactics built to bypass careful review - Does this add up? — flags amounts that break the sender's pattern - Who's really asking? — catches impersonation and secrecy patterns ➤ How it works 1.
