Cloudflare Activates Post-Quantum Encryption Across All Global Edge Nodes by Default
Cloudflare has reached a milestone in internet security by enforcing **post-quantum cryptography (PQC)** by default across its entire global edge network. All TLS 1.3 connections terminated at Cloudflare's 300+ edge locations now utilize NIST-standardized key encapsulation mechanisms to neutralize future quantum computing decryption threats.
Key Takeaway & Industry Impact
Cloudflare makes NIST-standardized post-quantum cryptography the default for all customer traffic across its 300+ global edge data centers.
The rollout incorporates ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism, formerly Kyber) alongside traditional Elliptic Curve Diffie-Hellman (ECDH) key exchanges. This hybrid approach guarantees backwards compatibility with legacy browsers while immediately protecting traffic against 'harvest now, decrypt later' eavesdropping campaigns.
