Endigest AI Core Summary
Cloudflare introduces Programmable Flow Protection, a beta feature for Magic Transit Enterprise customers that lets them deploy custom eBPF-based DDoS mitigation logic across Cloudflare's global network.
•Targets the gap in protecting custom or proprietary UDP protocols that Cloudflare's existing systems cannot interpret
•Customers write their own eBPF programs defining what constitutes "good" or "bad" packets, and Cloudflare executes them on every incoming packet network-wide
•Programs run in userspace (not kernel space) after all existing Cloudflare DDoS mitigations, preserving standard protections while adding customization
•Helper functions are provided for stateful client tracking, cryptographic validation, and challenge packet emission
•
Goes beyond traditional firewalls by supporting stateful flow tracking and client challenge mechanisms, enabling defense against replay attacks
