Cloudflare Launches Certificate Authority Built for the Quantum Computing Era

Dark Reading · 30 Sept 2026

Key Takeaway Australian SMBs don't need to act immediately, but should start asking their web hosting and IT providers about plans to adopt post-quantum encryption standards.

Cloudflare has revealed a new public certificate authority aimed at preparing the web for the eventual arrival of quantum computing. The service is designed to issue automated digital certificates, the credentials that let browsers verify a website is genuine and encrypt traffic to it, while being hardened against future quantum-based attacks that could break today's encryption standards.

Digital certificates already underpin the secure padlock icon seen on most websites, and Cloudflare's move signals that certificate authorities are beginning to build quantum resistance into everyday internet infrastructure now, rather than waiting until quantum computers become a practical threat. This is part of a broader industry shift toward 'post-quantum' cryptography, which experts warn businesses should start planning for well ahead of time.
