Cloudflare has expanded its Zero Trust Network Access solution to include post-quantum cryptography, making it the first cloud-based solution to do so.
Zero Trust Network Access is a security model that works by continuously verifying users and devices before granting access, ensuring only the right people can connect to corporate applications.
With the addition of post-quantum cryptography, this access is now protected by encryption that’s designed to stand strong against the future power of quantum computers.
“Cloudflare has long committed to making post-quantum security the new baseline for Internet security, delivering it to all customers so we can bolster defenses against future quantum threats. Now, we’re offering that protection built directly into our Zero Trust solutions,” said Matthew Prince, co-founder and CEO at Cloudflare.
“We want every Cloudflare customer to have a clear path to quantum safety, and we are already working with some of the most innovative banks, ISPs, and governments around the world as they begin their journeys to quantum security. We will continue to make advanced cryptography accessible to everyone, at no cost, in all of our products.”
Quantum computers, when fully developed, could process information much faster than today’s computers. This power could allow them to break current encryption methods, which are used to protect sensitive data — and are currently considered unbreakable.
Cloudflare plans to expand its post-quantum cryptography support by mid-2025 to cover all IP protocols. This will improve compatibility with more corporate applications and devices.
“The world has five years to replace vulnerable cryptography with post-quantum solutions. “To meet this urgent client need, Accenture and Cloudflare offer a hybrid approach, enabling an iterative, low-risk migration while maintaining compatibility and cryptographic agility,” said Tom Patterson, emerging technology security lead at Accenture.
The National Institute of Standards and Technology aims to phase out outdated encryption methods by 2030, stressing the need to adopt post-quantum cryptography.
Other companies are also staying ahead of the game. ExpressVPN, the no. 1 VPN on the market, also has built-in protections against potential quantum computing threats in its proprietary Lightway protocol.
