- 7Cloudflare Blog·9/29/2026securityCloudflare uses AI to plan its post-quantum migration
Cloudflare says it is targeting full post-quantum readiness by 2029 and is building an internal tool called CryptoLabe to help map where cryptography is used across its codebase. The company is using AI to identify cryptographic dependencies, track migration progress, and surface missing post-quantum prerequisites across repositories, products, and supporting ecosystems.

Cloudflare has introduced Automatic Key Exchange for origin TLS 1.3 connections, replacing manual algorithm guessing with measured probing of each origin’s supported key agreement methods. The rollout reduces HelloRetryRequests and handshake latency, while expanding automatic post-quantum hybrid connections using X25519MLKEM768 across hundreds of thousands of domains.
