Bringing more transparency to post-quantum usage, encrypted messaging, and routing security

Cloudflare Radar has introduced new security-related data sets and tools, expanding its already extensive insights into various security threats such as application and network layer attacks, malicious emails, and Internet routing. The updates include enhanced post-quantum (PQ) monitoring for origin-facing connections and a tool for checking website PQ encryption compatibility. A Key Transparency section now provides real-time verification of end-to-end encrypted messaging services' key logs, while routing security insights have been expanded with global, country, and network-level information on ASPA deployment to prevent BGP route leaks. The platform tracks the growth of post-quantum encryption support, with significant adoption increases since early 2025, and now offers visibility into the post-quantum readiness of origin servers. Furthermore, Cloudflare has launched a tool to test hostname support for post-quantum encryption and introduced a Go container for compatibility checks. The Routing section now includes comprehensive RPKI ASPA support to track the adoption of this emerging routing standard, providing detailed insights into ASPA records and adoption trends. These enhancements aim to improve routing security, transparency, and post-quantum insights, with data accessible through the Radar API for further analysis and integration.
