Deadbolt — Fraud Firewall

Stops card-testing bots at checkout and shows you exactly what it caught, in plain English.

Card-testing bots hammer stores with bursts of tiny orders from throwaway emails, checking stolen cards a few dollars at a time. Deadbolt blocks the matching attempt while checkout is still in progress, and logs every catch in plain English so you always know what it did and why. Turn it on in one click, try test mode first, and tune the rules to your store. Advanced protection adds disposable-email blocking, custom domain blocklists, and the Protection Report.

• Stops bursts of tiny orders from throwaway emails during checkout
• Plain-English activity log of every order it flags — no black box
• Safe test mode to preview what it would block before you enforce it
• Adjustable order-value threshold and your own custom email-domain blocklists
