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.
