Cloudflare expands Zero Trust Network Access with post-quantum cryptography

Cloudflare is expanding its Zero Trust Network Access solution by integrating Post-Quantum Cryptography (PQC) to enhance communication security. The new feature will allow organizations to secure data routing from web browsers to corporate applications, creating a quantum-safe connection. Full support for all IP protocols is expected to be available by mid-2025, streamlining the transition to advanced security measures without requiring extensive upgrades to existing systems.

As quantum computing approaches practical application, traditional encryption methods face risks of being compromised. Cloudflare's solution aims to preemptively address these risks by adopting PQC, which the National Institute of Standards and Technology (NIST) has recommended transitioning to by 2030. In response to this urgency, Cloudflare has committed to making post-quantum security available to all its customers at no additional cost.

Matthew Prince, co-founder and CEO of Cloudflare, stated, “We want every Cloudflare customer to have a clear path to quantum safety.” The company has been collaborating with various sectors, including finance and governance, to prepare them for future security needs.

Cloudflare’s Secure Web Gateway (SWG) and Access network configurations are currently available, with additional features set to roll out in the coming years. The company highlights the importance of migrating to post-quantum solutions within the next five years to protect against potential encryption vulnerabilities.
