Defend against frontier cyber models: Cloudflare's architecture as customer zero

This post details Cloudflare's internal architecture and security practices for defending against advanced AI-driven cyber threats, positioning itself as 'customer zero' for its own security products. It elaborates on how Cloudflare uses its WAF (with ML-based scoring and threat intelligence integration), API Shield (positive security model), Bot Management, Zero Trust Network Access, and IdP Federation to create layered defenses. The post emphasizes the shift from signature-based detection to ML-based scoring for faster response to novel exploits and the architectural principle of containing vulnerabilities to limit attacker lateral movement. It also discusses the speed of threat intelligence dissemination and the importance of visibility across the network.
