What is an SSL certificate?

An SSL certificate is a small digital file that encrypts the connection between your website and its visitors, so the data they send stays private. It powers the padlock and https in the browser.

SSL certificate, explained

An SSL certificate scrambles the information travelling between a visitor's browser and your website, so anything they type, like a name or an email in a contact form, cannot be read by anyone snooping in between. It also proves your site is really yours and not an impostor. When a site has one, the browser shows a padlock and the address begins with https instead of http.

It matters because visitors have learned to look for that padlock before they trust a site with their details. Modern browsers even flag pages without SSL as "Not secure", which can scare people away in seconds. Search engines also prefer secure sites, so SSL quietly supports your visibility too. Imagine a customer filling in your enquiry form: SSL is what keeps their message private on its way to you. It works hand in hand with your custom domain and reliable web hosting to make your site feel safe and professional.

How it works in Promino

Promino issues and renews an SSL certificate for every published site automatically, at no extra cost. You do not have to buy one, install it, or remember to renew it before it expires.

The moment you connect your domain and publish, your site is served securely over https with the padlock in place. It stays that way for good, with renewals handled quietly in the background. See how it fits together on our web hosting page.
