Cloudflare targets 2029 for full post‑quantum cryptography migration
The infrastructure provider outlines its roadmap to replace classical cryptography with quantum‑resistant methods by 2029.
By Felo News Desk · Published
Cloudflare announced that it is working toward full post‑quantum cryptography readiness across its platform by 2029, according to a blog post published on September 29, 2026.
The company says many of its products have already been upgraded to post‑quantum encryption over TLS 1.3, but it still needs to address the long tail of TLS connections and introduce post‑quantum authentication. Cloudflare’s migration plan rests on three goals: helping product and engineering teams understand current cryptographic usage and upgrade paths, providing metrics on per‑repository and per‑product use of classical versus post‑quantum schemes, and surfacing prerequisites early when protocols lack a migration plan.
Cloudflare describes its stance as “PQ everything!” and frames the effort as essential for an infrastructure provider that wants to give customers confidence that their traffic will remain secure against future quantum adversaries.
