Cloudflare Targets 2029 For Full Post-Quantum Security
Cloudflare, Tuesday, April 7th, 2026
Cloudflare is accelerating its post-quantum roadmap. We now target 2029 to be fully post-quantum (PQ) secure including, crucially, post-quantum authentication.
At Cloudflare, we believe in making the Internet private and secure by default. We started by offering free universal SSL certificates in 2014, began preparing our post-quantum migration in 2019, and enabled post-quantum encryption for all websites and APIs in 2022, mitigating harvest-now/decrypt-later attacks.
While we're excited by the fact that over 65% of human traffic to Cloudflare is post-quantum encrypted, our work is not done until authentication is also upgraded. Credible new research and rapid industry developments suggest that the deadline to migrate is much sooner than expected. This is a challenge that any organization must treat with urgency, which is why we're expediting our own internal Q-Day readiness timeline.
