How a Leading LATAM Acquirer Increased approval rates by +3pp and reduced 3DS usage by 20% without increasing chargebacks

Context

Tier-1 regional e-commerce acquirer with high CNP volume and strong pressure to improve approval rates. Two anti-fraud solutions in place (external + in-house), both rules-based, with no machine learning and high engineering effort required to operate and maintain.

Initial Challenges

Chargebacks under control, but low approval rates and high false positives
Excessive use of 3DS
High friction and increased costs for merchants

Challenge

Improve approval rates and reduce 3DS usage while maintaining a low chargeback rate.

Solutions

We implemented GatekeeperX, our real-time fraud prevention solution, replacing both the external provider and the in-house system.
