SSL Certificate

A digital security certificate that encrypts data between your website and visitors, enabling the padlock icon and HTTPS in browsers.

SSL Certificate

An SSL certificate (Secure Sockets Layer) is a digital file that authenticates your website's identity and enables encrypted connections between your server and visitors' browsers.

When a site has an SSL certificate, the browser shows:

  • A padlock icon in the address bar
  • https:// instead of http://

Why You Need One

  1. Security — Encrypts sensitive data (forms, payments, logins)
  2. SEO — Google uses HTTPS as a ranking signal
  3. Trust — Browsers warn users about non-HTTPS sites
  4. Required for payments — PCI compliance requires HTTPS
