Cloudflare adds post-quantum authentication for origin connections

Cloudflare has extended post-quantum protections beyond browser-facing traffic and into the connection between its edge and customer origins. Support now includes post-quantum authentication for Authenticated Origin Pulls and Custom Origin Trust Store, closing an important gap in many modern edge architectures. The move strengthens Cloudflare's position in the race to make production-grade post-quantum security practical across the full request path.
