Cloudflare has introduced end-to-end post-quantum cryptography support for its Zero Trust Network Access (ZTNA) solution, establishing itself as the first provider of quantum-ready zero trust security in the cloud security market.
Effective immediately, organizations can route web browser communications to corporate applications through Cloudflare’s network with quantum-safe connectivity. The company plans to extend this capability to all IP protocols by mid-2025, enabling broad compatibility across corporate applications and devices.
This development comes as quantum computing advances threaten current encryption standards. The National Institute of Standards and Technology (NIST) has announced plans to phase out conventional cryptographic algorithms by 2030, with experts warning significant security risks could emerge within five years.
Cloudflare’s solution specifically addresses “harvest-now decrypt-later” attacks, where adversaries collect encrypted data today to decrypt later when quantum computing capabilities mature. The solution enables quantum security for corporate web applications without requiring individual upgrades to each application’s security infrastructure.
“Cloudflare has long committed to making post-quantum security the new baseline for Internet security,” said Matthew Prince, co-founder and CEO. “We want every Cloudflare customer to have a clear path to quantum safety.”
Since 2017, Cloudflare has been developing post-quantum cryptography, with over 35 percent of human-generated traffic on its network now benefiting from quantum-resistant protection.
By mid-2025, organizations using Cloudflare’s WARP device client will gain end-to-end quantum protection for any protocol connected through Cloudflare’s network configurations. “The world has five years to replace vulnerable cryptography with post-quantum solutions,” said Tom Patterson from Accenture, which partners with Cloudflare to offer migration assistance.
