Ever noticed that little padlock next to your site's address in the browser? It's not just a visual detail — it's the SSL certificate, and today it's practically mandatory for any site that wants to be taken seriously.
SSL (Secure Sockets Layer) creates an encrypted connection between the visitor's browser and your site's server. Without it, any information typed in — a password, card details, a contact form — travels in plain text and can be intercepted. With SSL active, the address changes from http:// to https://, and the browser shows the padlock.
Just open your site and look at the address bar. If a closed padlock shows up, the certificate is active and valid. If you see a "not secure" warning or an open/red padlock, it's time to act — most reputable hosting providers offer free SSL certificates (via Let's Encrypt, for example) that can be enabled in a few clicks.
At the end of the day, the green padlock is no longer a technical nice-to-have: it's the bare minimum any visitor expects before trusting a site with their data.
