What is an SSL Certificate Jargon Busted vlog Six Two Tech

What is an SSL Certificate?

SSL. 3 little letters, but so important. In this episode we explain why if your website doesn’t have an SSL Certificate, it’s not just dangerous, but bad for business.

This is episode 14 of Jargon Busted, a series our COO Helen demystifies common website terms in just 2 minutes. Our company, Six Two, specialises in web design in Ashford Kent.


Hello, welcome to Jargon Busted, where I demystify a piece of website jargon in two minutes. Today I’ll be talking about SSL certificates.

If you’ve ever been on a website and seen a little padlock symbol or green bar next to the website address, that means the site has an SSL certificate.

SSL stands for Secure Sockets Layer but that’s not important; what is important is what it does for your website. It ensures that any data sent to and from your website is encrypted. For example, if someone places an order or sends you an enquiry via a contact form, the data that gets sent back to you is encrypted, safe and secure.

When you have an SSL installed, instead of seeing HTTP at the start of your website address, you’ll see HTTPS. That extra S stands for secure.

Now, it used to be that only e-commerce sites had SSLs, however, a year or two ago, Google started penalising websites that don’t have an SSL.

If you’ve ever tried to visit a site and get a message saying, ‘This site isn’t secure and may be trying to steal your personal information’ it’s likely because the site doesn’t have an SSL or it’s expired. This means that every website needs an SSL if you don’t want your customers to be warned your site is insecure or malicious.

If you’re using a website builder such as Wix, Shopify or Squarespace, they come as part of the package. If you have a bespoke or template website, SSLs can be set up by your web developer or hosting provider, and you can now get SSLs for free, via a service called Let’s Encrypt. They’re valid for three months and you can renew them as many times as you like, and most hosting providers will do this automatically for you. That’s it for now.
