Formhouse CheckoutGuard helps you spot unusual order patterns linked to automated checkout abuse and card-testing-style activity—then respond with rules you control. In Monitor, baselines come from completed orders with risk scores and alerts—checkout stays open. With Shield, sync validation rules such as min order value, guest/low-value limits, and quantity caps. You choose when to enforce. No card numbers; no guaranteed fraud prevention. Runs on Shopify.

• Monitor order anomalies and attack-style alerts without blocking.
• Sync merchant-configured Shield rules to Shopify cart validation.
• Minimal scopes and pseudonymous analytics—no card data access.
