Cloudflare, Inc., a connectivity cloud company, has announced an expansion of its end-to-end support for post-quantum cryptography within its Zero Trust Network Access solution. Organizations can now secure communications from web browsers to corporate applications with immediate, quantum-safe connectivity. By mid-2025, Cloudflare will extend this security to all IP protocols, ensuring compatibility across a wide range of corporate applications and devices.

As quantum computing advances, conventional encryption methods face increasing threats. Sensitive data—from financial transactions to healthcare records—could become vulnerable to decryption by quantum computers. The National Institute of Standards and Technology (NIST) has recognized this risk, setting a 2030 deadline to phase out outdated cryptographic algorithms. Experts warn that post-quantum security threats could emerge within five years, making immediate action crucial.

Cloudflare has been a pioneer in post-quantum cryptography, integrating advanced encryption as a default feature across its products. “Cloudflare has long committed to making post-quantum security the new baseline for Internet security,” said Matthew Prince, co-founder and CEO at Cloudflare. “Now, we’re offering that protection built directly into our Zero Trust solutions, ensuring our customers have a clear path to quantum safety.”

With this latest expansion, Cloudflare’s Zero Trust Platform will enable organizations to:

• Prevent ‘harvest-now, decrypt-later’ attacks – Protect encrypted data from future quantum decryption threats by routing web traffic through Cloudflare’s global network.
• Enable end-to-end quantum security for corporate applications – Secure web applications like HR, payroll, and collaboration tools without the need for individual security upgrades.
• Ensure quantum safety for all Internet traffic – By mid-2025, Cloudflare’s WARP device client will offer seamless quantum security for corporate offices, cloud environments, and data centers.

Tom Patterson, Emerging Technology Security Lead at Accenture, emphasized the urgency: “The world has five years to replace vulnerable cryptography with post-quantum solutions. To meet this need, Accenture and Cloudflare are providing a hybrid, low-risk migration path to maintain security and cryptographic agility.”

Cloudflare continues to lead in securing Internet communications against future quantum threats, ensuring businesses stay protected in the evolving cybersecurity landscape.
