Payment Fraud Detection Platform for Telcos & MSPs
Enterprise-grade real-time fraud detection system with sub-10ms latency, 5 detection signals, hot-reload policy engine, and complete evidence capture.
Overview
A comprehensive fraud detection platform designed for high-throughput payment processing environments. The system processes authorization requests in real-time, applying multiple detection signals including card testing detection, velocity analysis, geographic anomalies, bot/emulator detection, and friendly fraud scoring.
Key architectural decisions include a three-path data architecture (request-time, real-time Redis, async PostgreSQL), profit-based threshold optimization, and a hot-reload policy engine using YAML configuration. The platform achieves sub-10ms decision latency at 260+ requests per second with full evidence capture for dispute resolution.
