RESTON, Va.–(BUSINESS WIRE)–Nacha announced that Trustmi has become a Nacha Preferred Partner for Risk and Fraud Prevention, Fraud Monitoring, and Account Validation.
Trustmi’s behavioral artificial intelligence platform is built to help detect and stop ACH payments authorized under False Pretenses—including business email compromise, vendor impersonation, and payment redirection—before money moves. By analyzing historical payment data, vendor communications, invoice patterns, and banking detail history, the AI engine establishes entity-specific baselines, against which each payment is scored. Deviations trigger automated alerts or payment blocks before ACH entries are initiated.
“Nacha continues to be focused on solutions for credit-push fraud,” said Jane Larimer, Nacha President and CEO. “We are pleased to welcome Trustmi as a Nacha Preferred Partner.”
“Most organizations aren’t prepared for continuous, risk-based fraud monitoring,” said Shai Gabay, Co-Founder and CEO of Trustmi. “What we’ve been seeing for years is that the most dangerous fraud is the kind that appears authorized. Trustmi enables organizations to detect this fraud by establishing behavioral baselines and stopping anomalous payments in real time, before they reach the ACH Network.”
Nacha’s Preferred Partner Program is open to any technology solution provider whose offerings align with the Nacha strategy of advancing the ACH Network. For more information about the program, visit Nacha’s Preferred Partner page.
