Provide a managed service that monitors payment and checkout activity, reviews flagged orders before capture or fulfillment, blocks card-testing patterns, and escalates incidents using documented evidence. Begin with human review and merchant-approved playbooks, then productize recurring detection rules, case records, and processor-specific response templates.

Automated attacks can generate transaction volume faster than small merchants can review it, while payment processors increasingly make consequential risk decisions automatically. Merchants need operational coverage that works across their storefront, payment processor, and fulfillment process.
