Cloudflare Accelerates Post-Quantum Roadmap as Quantum Computing Threat Looms

Cloudflare, a web infrastructure company, has announced that it will accelerate its efforts to replace internet cryptography vulnerable to quantum computing attacks. The company aims to make its entire platform resistant to these threats by 2029.

The move reflects growing concern in the tech industry about the potential for 'Q-Day', when a powerful quantum machine could break current cryptographic systems. This has led companies like Google and Cloudflare to speed up their migration schedules to post-quantum authentication and encryption.

Cloudflare's post-quantum roadmap involves rolling out post-quantum authentication for origin connections by mid-2026, expanding it to visitor connections in mid-2027, and extending support across its enterprise networking platform by early 2028. The company mitigated much of this risk by enabling post-quantum encryption across most of its products starting in 2022.
