Summary
This post introduces new data sets and tools on Cloudflare Radar to enhance visibility into post-quantum (PQ) encryption support, encrypted messaging security, and routing security. It extends PQ monitoring to origin-facing connections, providing a graph of customer origins supporting X25519MLKEM768 and a tool to test individual hostnames for PQ support. The post also launches a Key Transparency section on Radar, displaying audit data for logs of end-to-end encrypted messaging services like WhatsApp and Facebook Messenger Transport. Finally, it expands Routing Security insights with ASPA deployment information at global, country, and network levels.
