Cloudflare has introduced several new updates to its Radar platform, focusing on stronger Internet security and better transparency. These updates bring deeper insights into post-quantum encryption, end-to-end encrypted messaging systems, and routing security trends across global networks.
As online threats continue to evolve, tools that provide real-time visibility into encryption and network protection are becoming more important for businesses, developers, and security researchers.
Post-Quantum Encryption Monitoring Gets a Major Upgrade
One of the biggest improvements is expanded monitoring for post-quantum encryption. Earlier, Cloudflare Radar mainly tracked client-side support. Now, it also measures encryption support between Cloudflare servers and origin servers.
Post-quantum encryption is designed to protect data from future quantum computing threats. The new Radar tools allow users to test whether a website supports post-quantum secure connections. This helps organizations understand whether their infrastructure is ready for the next generation of cryptography.
Cloudflare data shows that support for post-quantum encryption has grown rapidly, increasing from very low adoption levels in 2024 to strong global growth by 2026. This trend reflects the industry’s shift toward stronger encryption standards.
Key Transparency Improves Trust in Encrypted Messaging
Cloudflare has also introduced a new Key Transparency section that improves visibility into end-to-end encrypted messaging platforms such as WhatsApp, Signal Messenger, and Facebook Messenger.
End-to-end encryption ensures that only the sender and receiver can read messages. However, users must trust that the correct encryption keys are being used. Key Transparency solves this challenge by creating public logs that can be independently verified.
The new Radar dashboard shows whether encryption logs are active, when they were last verified, and whether any changes occurred. This makes encrypted communication more trustworthy and easier to audit.

Routing Security Insights with ASPA Tracking
Another important addition is improved routing security visibility through ASPA (Autonomous System Provider Authorization). Internet routing depends on complex connections between networks, and mistakes or attacks can redirect traffic incorrectly.
The new Radar tools help track how networks adopt ASPA to prevent route leaks and hijacks. Users can now view global and regional adoption trends, along with detailed network-level data.
This feature is especially useful for network operators who need to verify that their routing configurations are secure.
Key Security Updates at a Glance
| Feature Area | New Update | Benefit |

| Messaging Security | Key Transparency dashboard | Better trust in encrypted communication |
| Routing Security | ASPA adoption tracking | Improved network protection |
| Radar Data Tools | Expanded real-time datasets | Better security analysis |
Why These Updates Matter
Internet security is constantly changing, and organizations need clear visibility into how encryption and routing technologies are evolving. With these new updates, Cloudflare Radar becomes an even more powerful platform for tracking security readiness across the Internet.
By improving transparency in post-quantum encryption, encrypted messaging, and routing validation, these tools help create a safer and more reliable digital ecosystem for the future.
