Cloudflare has upgraded its WARP client to support post-quantum cryptography (PQC) ahead of the NIST deadline. This enhancement provides immediate protection for Internet traffic against potential quantum attacks. The WARP client now ensures end-to-end quantum encryption for both consumer and enterprise users.
- ▪The US National Institute of Standards and Technology has mandated the deprecation of classical cryptography by 2030.
- ▪Over 45% of Internet traffic to Cloudflare is already post-quantum encrypted.
- ▪The WARP client wraps user traffic in a post-quantum encrypted MASQUE tunnel for enhanced security.

Securing today for the quantum future: WARP client now supports post-quantum cryptography (PQC)2025-09-24Sharon GoldbergTochukwu Nkemdilim (Toks)Koko Uko10 min readThis post is also available in 简体中文.The Internet is currently transitioning to post-quantum cryptography (PQC) in preparation for Q-Day, when quantum computers break the classical cryptography that underpins all modern computer systems. The US National Institute of Standards and Technology (NIST) recognized the urgency of this transition, announcing that classical cryptography (RSA, Elliptic Curve Cryptography (ECC)) must be deprecated by 2030 and completely disallowed by 2035.Cloudflare is well ahead of NIST’s schedule.
