Today we are excited to announce a contribution to improving privacy for everyone on the Internet. Encrypted Client Hello, a new proposed standard that prevents networks from snooping on which websites a user is visiting, is now available on all Cloudflare plans. Encrypted Client Hello (ECH) is a successor to ESNI and masks the Server Name Indication (SNI) that is used to negotiate a TLS handshake. This means that whenever a user visits a website on Cloudflare that has ECH enabled, no one except for the user, Cloudflare, and the website owner will be able to determine which website was visited. Cloudflare is a big proponent of privacy for everyone and is excited about the prospects of bringing this technology to life.
