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.

"As a fraud analyst focused on payment fraud, account takeovers, and phishing, I see these attack patterns every day. Small businesses face the same threats — but without any of the tools. I built PaySentinel to change that."
