# HTTPS

Concept · [Cloud, hosting and security](https://ecosystem.samcarlton.com/cloud)

Also called: SSL, TLS, SSL certificate, TLS certificate, certificate, SSL/TLS, secure site, padlock, http

The secure version of the way [browsers](https://ecosystem.samcarlton.com/web-browser) talk to websites. It [encrypts](https://ecosystem.samcarlton.com/encryption) the traffic and uses a certificate to confirm the site controls its [domain](https://ecosystem.samcarlton.com/domain). SSL is the older name for TLS, the technology underneath.

**For example:** A [browser](https://ecosystem.samcarlton.com/web-browser) shows a warning on a site whose certificate expired. The host renews the certificate and the warning goes away.
