Which protocol is used to protect data in transit on the web?

Explanation:
Protecting data as it travels across the web relies on a protocol that creates an encrypted, authenticated channel between your browser and the web server. TLS/SSL does exactly that: it negotiates keys, authenticates the server with a certificate, and then encrypts the transmitted data so it can’t be read or tampered with. This is why web traffic shown as HTTPS is secured—HTTP runs over TLS/SSL to shield the data in transit. The other options are protocols for email or file transfer, which don’t inherently secure web data in transit on their own (though some can use TLS in other contexts).
