FraudToad looks for card testing: stolen cards run through cheap orders, one new account at a time. It links each order to your other recent orders by card, IP address, email, customer and browser, scores it with rules you can read and adjust, and holds, cancels or blocks it. It starts in shadow mode: it only tags risky orders and shows what it would have done until you switch it on. With manual capture, cancelled orders are voided before capture, so there's no sale to refund.

• Scores each order against recent ones by shared card, IP, email and browser
• Holds risky orders for review with every rule that fired and why
• Voids card tests before capture and sweeps up the rest of the burst
• Checkout lock and card hiding stop testers before they can pay
• Starts in shadow mode; test the rules on your last 60 days of orders
