Breaking Down the New Visa Acquirer Monitoring Program (VAMP) Rules

Published on: 18th March, 2025

Fraudology is presented by Persona.

In this eye-opening episode of the Fraudology Podcast, host Karisse Hendrick dives deep into the controversial new Visa Acquirer Monitoring Program (VAMP) set to launch on April 1st. Fresh from attending the Merchant Risk Council's annual conference in Las Vegas, Karisse shares exclusive insights on how this program is causing major concern among merchants and acquirers.

She breaks down the complex VAMP ratio calculation, explaining how it combines TC40 fraud alerts and TC15 non-fraud disputes, and details the strict new thresholds that could lead to hefty fines. Karisse highlights a crucial last-minute change announced by Visa: popular chargeback deflection methods like Rapid Dispute Resolution (RDR) and CDRN alerts will no longer exclude transactions from the VAMP ratio for fraud-related disputes.

This unexpected shift is leaving many scrambling to adjust their strategies with little time before implementation. The episode also explores potential conflicts of interest, as Visa's Order Insight emerges as the only product capable of deflecting TC40s and TC15s.

Don't miss this critical update on a program that could significantly impact the e-commerce fraud landscape. Tune in now to arm yourself with the knowledge you need to navigate these upcoming changes.

If you work in online fraud prevention, chances are you've caught the "bug". The bug that makes you passionate about identifying & preventing cybercriminals from getting away with stealing from your company, or your client's companies. Most people who have made cyber-fraud their career have the perfect balance of analytical and social skills, a strong sense of justice and the curiosity that will drive you to go down every path of information until you "crack the case".
