The End of ISP Snooping: How Encrypted Client Hello Reclaims Your Digital Footprint
Encrypted Client Hello (ECH) represents a significant evolution in web security, addressing a critical privacy gap left by standard HTTPS. While modern encryption hides the data you send, the Server Name Indication (SNI) traditionally left the website's domain name exposed to network operators and ISPs. ECH closes this gap by encrypting the initial handshake between the client and the server, effectively blinding third parties to your browsing destinations. As major browsers adopt this standard, users gain a layer of stealth that previously required a VPN, marking a new era of native, metadata-level privacy for the general public.
