What We Check

Built on real fraud analyst rules.

Not generic AI — fraud detection logic built by a specialist in payment fraud, account takeovers, and phishing.

🏦

Bank Detail Changes

Catches "we recently changed our banking institution" — the #1 phrase in BEC invoice redirect fraud. Routing numbers verified against the Federal Reserve database in real time.

👻

Fake Vendor Detection

Phantom vendors — completely fake companies set up to collect payments — often run for months undetected. PaySentinel flags the signals: no web presence, P.O. box only, Gmail address, low invoice numbers.

🔤

Typosquat Domains

Character-by-character domain analysis catches mlcr0soft.com vs microsoft.com. Every substitution identified — 0 for o, l for i, rn for m — and explained in plain English.

📄

PDF Invoice Upload

Upload any invoice PDF — AI extracts all fields automatically including routing numbers, addresses, and payment instructions. No manual typing required.

🔗

Phishing Link Analysis

Paste any suspicious link before clicking. We check the destination domain for credential harvesting sites, cloned login pages, and lookalike attacks.
