Is your domain using post-quantum encryption? Now you can see for yourself

Today, we are introducing additional post-quantum (PQ) cryptography visibility tools into Cloudflare's Application Security and Logs products. You can now inspect and graph the adoption of post-quantum TLS 1.3 encryption for live traffic from directly within Logpush, Log Explorer, and the HTTP Traffic Analytics dashboard. By surfacing the key exchange algorithm negotiated on every incoming request from visitors to our platform, Cloudflare gives customers granular, per-connection telemetry to audit their post-quantum posture, assess compliance, and identify cryptographic gaps across their domains.

Cloudflare is targeting 2029 for full post-quantum security, and executing a cryptographic transition at scale requires detailed telemetry. We’ve already deployed post-quantum encryption across many of our products, including in our cloud-proxy platform and on every on-ramp and off-ramp of our SASE platform.   As many of our customers work towards quantum-readiness deadlines around 2030, we’re helping ease the transition by making post-quantum encryption the default in many of our products, sharing learnings from our internal cryptography discovery tool, and launching the new post-quantum visibility features for TLS that we’ll cover in this blog.
