Why GMAP matters

GMAP Is More Than a Chargeback Monitoring Update

GMAP introduces a broader way to evaluate fraud and dispute activity. It does not only look at chargebacks. It also considers fraud reported to Mastercard’s Fraud & Loss Database, which means risk can build before a traditional chargeback ever appears.

Fraud and disputes are now connected

GMAP combines fraud and dispute activity into a more complete risk picture.

Monitoring becomes more proactive

Merchants and portfolios can be reviewed monthly, with escalating consequences when thresholds are crossed.

Preparation starts before enforcement

The strongest strategy is to understand your exposure early and reduce the fraud and disputes that create GMAP risk.

The Fraud Deflect Difference
GMAP rewards prevention — not cleanup.
Why Fraud Deflect

Move Upstream Before Fraud and Disputes Become GMAP Exposure

Once fraud or disputes are reported, the number may already be working against you. Fraud Deflect helps merchants and acquirers move upstream by preventing fraudulent transactions before they process, resolving disputes before they become chargebacks, and improving visibility into the metrics that matter.

01

Stop fraud before it reaches the FLD

Fraud Deflect helps identify and block high-risk activity before it becomes reported fraud.

02

Resolve disputes before chargebacks

Issuer collaboration and dispute-resolution tools help reduce the activity that feeds monitoring thresholds.

03

Protect accounts and portfolios

Whether you are protecting one merchant account or managing portfolio exposure, the goal is the same: reduce the fraud and disputes that drive GMAP risk.
