Modern tools to prevent fraud, fully integrated with your payments.

Fraud prevention done right

Old ways of combating fraud were never designed for modern internet businesses. Stripe Radar is powered by advanced machine learning algorithms that automatically learn from Stripe’s global network of businesses to identify and prevent fraud.

  • Better accuracy

    Stripe Radar scans every transaction using the most relevant signals to detect and block fraud. And Radar’s algorithms are constantly tweaked by Stripe engineers to adapt to new fraud vectors.

  • Strength in numbers

    We pinpoint fraud by building behavioral signals from across 100,000+ global companies. (Even if a card is new to your business, there’s an 80% chance it’s been seen before on the Stripe network.)

  • Immediate results

    Unlike systems that require weeks to train and only mimic human reviewers, Radar lets you instantly use rich payments data (including info from banks and card networks) to fight fraud.

How is machine learning used to detect fraud?

We’ve put together a primer on how machine learning can produce predictive models of fraud from large sets of data. The more effective the system, the better it is at precisely detecting and blocking fraud.
