Stripe Radar

Stripe Radar is an AI-native fraud detection system built into the Stripe payments platform - using machine learning trained on hundreds of billions of transactions across Stripe's global network to score every payment for fraud risk and block fraudulent transactions in real time. AI capabilities include ML fraud scoring that evaluates each transaction against global network patterns, device fingerprinting and behavioral signals that identify suspicious activity, adaptive models that continuously learn from fraud patterns across the entire Stripe ecosystem, customizable rules engine that allows merchants to set their own fraud thresholds and blocking logic, 3D Secure orchestration that intelligently applies strong customer authentication only when risk warrants it, and detailed fraud analytics that surface fraud patterns and chargeback trends.

Stripe Radar is AI-native - ML fraud detection trained on the entire Stripe transaction network that autonomously scores and blocks fraud in real time is the core product architecture.
