Programmable Flow Protection for Custom UDP DDoS Mitigation
🛡️Programmable Flow Protection lets Magic Transit customers author and deploy custom eBPF programs across Cloudflare’s global edge to define what constitutes legitimate UDP traffic. Programs run in a verified userspace BPF VM and can pass, drop, or challenge packets using helper functions for state, cryptographic validation, and challenge emission. In beta for Magic Transit Enterprise customers, the feature enables stateful, protocol-aware DDoS mitigation that distinguishes legitimate clients from scripted or replay attacks.
