## Browser Support Detection for PQ Encryption on Cloudflare Radar

Oct 06, 2025 

[ Radar ](https://developers.cloudflare.com/radar/) 

[**Radar**](https://developers.cloudflare.com/radar/) now includes browser detection for Post-quantum (PQ) encryption. The [Post-quantum encryption card ↗](https://radar.cloudflare.com/adoption-and-usage#post-quantum-encryption) now checks whether a user’s browser supports post-quantum encryption. If support is detected, information about the key agreement in use is displayed.
