AI-Powered Fraud Detection: 85% Reduction in False Positives
How a leading global bank transformed fraud detection with our Multi-Agentic Framework
Client Overview
A Fortune 500 financial institution with over 50 million customers across 40 countries, processing more than $2 trillion in transactions annually. The bank needed to modernize its fraud detection capabilities to combat increasingly sophisticated fraud schemes while maintaining excellent customer experience.
The Challenge
The bank's legacy rule-based fraud detection system was generating an overwhelming number of false positives, resulting in:
- Over 60% false positive rate, causing customer frustration and card declines
- Manual review of 10,000+ flagged transactions daily, requiring 200+ analysts
- $15M annual operational costs for fraud investigation teams
- Inability to detect emerging fraud patterns in real-time
- Customer satisfaction scores declining due to legitimate transaction blocks
The bank needed an intelligent, adaptive solution that could learn from new fraud patterns while dramatically reducing false positives.
