Enhancing ACH Transaction Security for a Leading US Bank

Situation

As part of their due diligence, a leading US bank consulted with UMCA Technologies to weigh their options and obligations to comply with the 2026 NACHA ACH e-Transfer regulations.

Challenge

• Existing systems were not actively monitoring ACH e-Transfers to perform fraud analysis.
• While the client had all the necessary data in hand, they were not ready to process it in a way that would comply with NACHA regulations.

Action

Solution Assessment. UMCA’s team determined the platform was well suited for both compliance (post-processing) and as a safeguarding tool that identifies which transactions should be blocked if deemed fraudulent (pre-processing).

Two-stage implementation.

• Stage One: Ensure compliance — monitoring and reporting only, without blocking.
• Stage Two: Enabled transaction blocking based on client preference and comfort levels.

Integration. Achieved by first establishing field mapping via sample CSV, after which batch file processing was implemented.

Result

UMCA’s system was successfully integrated with the client, enabling enhanced fraud monitoring and prevention across their 100 million annual transactions, while also satisfying NACHA regulatory obligations.
