Challenge
A major bank was experiencing increasing fraud losses with their rule-based detection system unable to adapt to evolving fraud patterns. False positives were also causing customer friction.
Solution
We deployed a machine learning-based fraud detection system that analyzes transaction patterns in real-time, identifies anomalies, and learns from new fraud techniques. The system uses ensemble models for high accuracy.
Results
- 85% improvement in fraud detection rate
- 60% reduction in false positives
- $50M prevented in fraud losses annually
- <100ms detection latency
