Radar

Use Stripe Radar to protect your business against fraud.

Stripe Radar provides real-time fraud protection and requires no additional development time. Radar for Fraud Teams adds customization capabilities and deeper insights and trend analysis for your business. Radar for Platforms, currently in public preview, provides protection against both transaction and account risk.

Radar evaluates transactions in real-time, using AI algorithms to assess the risk of fraud. All Radar pricing tiers charge a fee for each transaction they evaluate, including the first transaction and all subsequent transactions for recurring payments. The exception is Stripe Billing users, who are only billed for the first transaction—subsequent transactions aren’t billed. Radar for Platforms also charges a connected account fee.

Radar screens all payment attempts types (such as successful, declined, blocked, and flagged for review) and the following payment method types:

Cards
Wallets (when the underlying payment method is a card)
ACH Direct Debit
SEPA Direct Debit

Radar doesn’t screen SetupIntents for non-card payment methods. Learn more about Radar’s features.
