Stop card testing before it reaches your payment processor. You choose when blocking starts.
Card testers try stolen cards at checkout until one is approved. Those attempts still reach your payment processor unless Shopify stops them first. Checkout Firewall turns your block list, trust list, and shared fraud matches into a checkout rule. A match can be stopped before payment. The app never sees card numbers. Checkout never calls an outside service. New installs start in Monitor and only log what would have been blocked. Switch to Balanced or Aggressive when you want checkout blocked.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Checkout Firewall on a store, it is there.
