Stop ACH fraud in real time
ACH payments continue to grow rapidly, increasing the potential for fraud across origination and receipt channels. In Q3 2025, the ACH Network processed 8.8 billion payments totaling $23.2 trillion—year-over-year increases of 5.2% in volume and 8.2% in value, according to Nacha (Nacha).
As ACH fraud increases with payment volume, it is important to find fraudulent credits and debits before processing. This helps reduce losses and protect customers. Abrigo Fraud Detection analyzes ACH files upon arrival to identify fraud in real time, streamlining investigations, improving efficiency, and supporting compliance with the Nacha risk management framework.
