Use ML that actually works
Radar helps detect and block fraud for any type of business using machine learning that trains on data across millions of global companies. It’s built into Stripe and requires no additional setup to get started.

Stop blocking legitimate customers
Old ways of combating fraud were never designed for modern internet businesses and can lead to lower acceptance rates and lost revenue. Radar can help you distinguish fraudsters from customers and apply Dynamic 3D Secure to high-risk payments.

Get protection that adapts to you
Our machine learning infrastructure lets us retrain models – including ones customised for your business – every day. Radar’s algorithms adapt quickly to shifting fraud patterns and to your unique business.

Trained with hundreds of billions of data points
Stripe processes payments from 195 countries for every industry, company size, and business model. Even if a card is new to your business, there’s an 89% chance it’s been seen before on the Stripe network.

Better accuracy than third-party tools
Radar ingests data from every layer of the financial stack and integrates data from checkout flows, rich payments data, and info from card networks and banks to assess fraud risk.

Sophisticated signals engineered for impact
Radar is built for global internet businesses facing evolving fraud threats. We constantly tweak our algorithms, test which attributes are most relevant, and generate compound signals to help precisely identify and block fraud.
