Radar

Trained on over a trillion dollars in annual payment volume

Stripe processes payments from 197 countries for every industry, company size, and business model. Even if a card is new to your business, there’s a 92% chance it’s been seen before on the Stripe network.

Strength in numbers

By learning from millions of global businesses processing more than $1.4 trillion in payments each year, Radar assigns risk scores to every payment and automatically blocks high-risk payments.

Better outcomes with AI 

Radar’s AI scans every payment using hundreds of signals from across the Stripe network to help detect and prevent fraud before it hits your business, reducing fraud by 38% on average.

More accurate than third-party tools

Radar ingests data from every layer of the financial stack, integrating checkout flow data, rich payments data, and card network and bank information to assess fraud risk.

Data from financial partners

Stripe’s partnerships with Visa, Mastercard, American Express, and leading banks let us use data like TC40s, SAFE reports, and early dispute notifications to help identify fraudulent charges before they’re disputed.

Data from payments

Radar is fully integrated with the rest of Stripe, so our systems can instantly use rich payment information— such as customer details, shipping and billing addresses, and other properties—to improve AI performance and block fraud.

Data from checkout flows

Stripe’s checkout tools automatically incorporate certain buyer patterns from your website and mobile app to help detect anomalous payments. Radar uses these signals to improve AI performance and block fraud on your behalf.

Sophisticated signals engineered for impact

Radar is built for global internet businesses facing evolving fraud threats. Radar constantly tweaks our AI algorithms, tests which attributes are most relevant, and generates compound signals to help precisely identify and block fraud.

Device fingerprints

Tie multiple signals into a single device profile.

Historical snapshots

Spot recurring patterns across years of historical data.

Proxy detection

Identify IP spoofing and proxy usage.

Cumulative impact

Radar scores every transaction by combining multiple signals to help determine whether a payment is fraudulent.
