Card enumeration attack prevention is the practice of stopping attackers who test thousands of guessed card numbers against a payment endpoint until one is confirmed valid. This solution answers that threat at the gate: real-time velocity limits, BIN-level monitoring, and adaptive verification flag brute-force patterns before a single working card is confirmed. It is built for merchants, gateways, and risk teams that need card-testing traffic filtered out without slowing down genuine buyers.

Key Features
- Real-time velocity limits applied per IP address, device, card BIN, and customer session

- Automated blocklists, webhook alerts, and exportable audit logs
- Drop-in REST API and plugins for common storefront and payment gateway stacks
What are the technical specifications?
The rules engine sits inline with your authorization flow and returns a decision in milliseconds, so checkout latency stays effectively unchanged. Thresholds, block windows, and challenge logic are configurable per merchant account, with separate profiles for card-not-present and subscription traffic. Event data is retained for audit and dispute review, and records can be exported to your existing SIEM or fraud analytics stack. Configuration is managed from a hosted dashboard, and no card data is stored outside your existing PCI-compliant environment.
