Activate Stripe Radar for fraud protection in online payments

This article explains how Stripe Radar helps protect against fraud in online payments processed via Stripe, which options are available, and what to consider when using advanced fraud protection features.

Overview

Stripe Radar is Stripe’s built-in fraud prevention tool for card payments. It uses machine learning to detect suspicious payment behaviour and helps block or review potentially fraudulent transactions in real time.

All Stripe accounts include a basic version of Stripe Radar by default. Organisations can optionally upgrade to paid versions for more advanced fraud control and monitoring.

Using Stripe Radar helps reduce fraud risk and protect organisations from financial loss.

How Stripe Radar works

Stripe Radar analyses each payment using:

• Machine learning models trained on millions of transactions worldwide

• Behavioural signals and risk patterns

• Configurable rules and block lists (depending on the plan)

Suspicious payments can be:

• Automatically blocked, or

• Flagged for manual review
