Cloudflare adds domain-level post-quantum encryption tracking

Cloudflare has introduced new tools that let customers see exactly which parts of their website traffic use post-quantum encryption—algorithms resistant to future quantum computers. These upgrades, now in Cloudflare’s security and analytics dashboards, allow domain-by-domain inspection of the encryption used for web requests, so companies can spot gaps and audit compliance ahead of looming 2030 quantum-security deadlines.

• Lets you graph post-quantum TLS 1.3 traffic per domain
• Now tracks key exchange algorithms used for every request
• About 70% of browser Cloudflare traffic is post-quantum
• Only 15% of origin connections use post-quantum today
• Cloudflare targeting 2029 for full post-quantum security
