How Castle is Building Codeless Customer Account Protection

This post details Castle's integration with Cloudflare Workers, Apps for Workers, and Workers KV to provide a codeless, edge-based customer account protection solution. It highlights how Workers are used to access request/response interactions at the edge without introducing latency, how Apps for Workers distribute the security logic, and how Workers KV stores configurations and user sessions. The post also explains the data flow, including script injection (Castle.js), collection of contextual information (IP, headers), and an advanced routing engine for recognizing security events.
