Trustpair

Trustpair attacks the exact moment most vendor fraud succeeds: the bank details. Nearly every fake-vendor and payment-diversion scheme ends the same way, someone gets a bank account number changed in your master file, via a spoofed email, a compromised vendor, or an insider, and the next payment run sends real money to the wrong account. Trustpair validates that an account actually belongs to the vendor on record, in 190 countries, and then keeps monitoring the vendor master file so a quiet IBAN edit on a Tuesday afternoon raises an alert instead of a wire.

The timing of its US push is not accidental. Nacha's fraud-monitoring rules that took effect in March 2026 put explicit expectations on ACH originators to monitor for exactly this kind of fraud, and Trustpair has leaned in hard with expanded US bank data coverage and liability protection up to $1 million on validated payments. That liability backstop is worth pausing on, a vendor that pays out when its own validation misses is making an unusually confident claim about its false-negative rate. The company says it has a zero-fraud track record across 550+ enterprise clients.

The fit check for this site's audience: Trustpair is enterprise software, custom-priced, integrated into SAP, Oracle, Coupa, and Kyriba-class systems, and sized for companies with thousands of vendors. A 20-person company can get most of the practical benefit with a strict callback-verification policy for any bank-detail change. But if you're mid-market or larger with a real AP department, this is the most direct anti-payment-diversion tool in the directory.
