Don’t Let Spoofed Emails Fool
You

SpoofShield uses AI to detect domain spoofing, sender impersonation, lookalike addresses, IRS scams, password-reset phishing, and social engineering tactics — alerting you in real time, inside Outlook and Gmail, before anyone acts on a fake email.

The Business Email Compromise Epidemic

$2.77 billion lost to email fraud
in 2024 alone

BEC (Business Email Compromise) is now the costliest cybercrime category tracked by the FBI — and it keeps growing. No malware. No malicious links. Just a well-crafted email targeting the right person.

Why email filters don’t stop it

Gateway filters catch malware and phishing links. But BEC (Business Email Compromise) attacks arrive as plain text — no attachments, no bad URLs, no suspicious domains. By the time Finance wires the money, the filter never saw a problem.

Mid-thread swap caughtHIGH RISK

“Forwarded chain shows payments@vendor.com in earlier messages. New reply comes from payments@vendor-invoicing.net — same display name, different domain.”
