• CSP-Sentinel Technical Design Document

  6 min read Dec 11, 2025

  CSP-Sentinel is a centralized, high-throughput system designed to collect, process, and analyze Content Security Policy (CSP) violation reports from web browsers. As our web properties serve tens of thousands of requests per second, the system must handle significant burst traffic (baseline 50k RPS, scaling to 100k+ RPS) while maintaining near-zero impact on client browsers.The system will leverage a modern, forward-looking stack (Java 25, Spring Boot 4, Kafka, Snowflake) to ensure long-term support and performance optimization. It features an asynchronous, decoupled architecture to guarantee reliability and scalability.
