Last month at Stripe Sessions, we shared the biggest expansion we’ve ever made to Stripe Radar, our AI-powered fraud prevention tool. Radar now blocks high-risk transactions across all supported payment methods; defends against new fraud types like multi-account abuse and pay-as-you-go abuse, regardless of which payment processor you use; and gives platforms new tools to evaluate and mitigate merchant risk on and off Stripe. We also launched additional ways to fight disputes with smarter evidence and automated evidence libraries.Here’s a closer look at what we announced.Protect more transactions with global payment coverage, new multiprocessor signals, and custom models
Fraud protection is getting more complex. Businesses need to defend across a range of payment methods, and they need more precision in the signals they use to catch fraud before it happens—on and off Stripe. Radar now addresses both, along with the ability to use custom fraud models. Block high-risk transactions across all supported global payment methods
Radar now protects all supported payment volume globally, including bank debits, buy now, pay later (BNPL) options, crypto, digital wallets, real-time payments, and cash vouchers. When Radar detects a fraudulent pattern on a transaction, that information becomes available to protect transactions across all payment methods. For example, if a fraudulent actor uses a stolen credit card at one business on Stripe, and we detect and block it, that same IP address and device fingerprint are now flagged across bank debits, wallets, and BNPL transactions network-wide. We found that Radar reduced suspected fraud by 71% during a five-month period for businesses using Affirm, Cash App, Klarna, and PayPal.
