Conventional cryptography is under threat. Upgrade to post-quantum cryptography with Cloudflare Zero Trust

Cloudflare announces the first phase of post-quantum cryptography in its Zero Trust platform, enabling end-to-end quantum-safe protection for clientless Access and Secure Web Gateway today, with WARP client-to-tunnel PQ support targeted for mid-2025. The report explains NIST’s deprecation timeline for RSA/ECC, the urgency of mitigating harvest-now-decrypt-later threats, and Cloudflare’s focus on TLS 1.3 hybrid ML-KEM key agreement (with future work on PQ digital signatures), leveraging its global network to protect corporate traffic without requiring immediate changes to every application.
