What is HTTPS?

HTTPS stands for Hypertext Transfer Protocol Secure. It's the safe version of the ordinary web protocol your browser uses to load pages. The difference is the S, for secure. With HTTPS, everything sent between a visitor and your website is scrambled so that no one snooping in between can read it. That matters especially when people type anything private, like a name, email, or message through a contact form. It relies on an SSL certificate, a small digital credential that proves your site is genuine and switches on the encryption.

You've seen HTTPS in action even if you didn't notice. It's the little padlock icon in the address bar and the reason a web address starts with https rather than http. Modern browsers now warn visitors when a site isn't secure, showing a Not Secure label that can scare people away. Search engines also prefer secure sites, so HTTPS quietly helps your credibility, your visitors' trust, and your visibility all at once. For any business site today, it isn't optional. It's the baseline expectation.

Every site published with Promino runs on HTTPS automatically. When you connect a domain, Promino provisions the security certificate for you and keeps it renewed, so the padlock is always there and your visitors never see a warning.

There's no certificate to buy, install, or remember to renew. It's simply part of publishing, whether you use a free Promino address or your own custom domain. Learn more about web hosting in Promino.
