SSL Certificate Buyer’s Guide: FAQ & Compare Best SSL Certificate Providers (Certification Authority)

With Google Chrome browser now labeling all websites using HTTP encryption as “not secure”, installing SSL and implementing HTTPS on your website is no longer an option.

If you were one of those website owners who are learning and switching to HTTPS for the first time – this article is for you. We will look into some important points you should know before buying a SSL certificate issues and compare 10 popular Certificate Authorities.

What is SSL and SSL Certificate?

Secured Socket Layer (SSL) is the technology that make sure data between two machines (in our case – a browser and a server) is transmitted securely in an encrypted connection (HTTPS).

An SSL Certificate is a digital certificate that confirm the identity of a website.

To implement SSL on your website, you will need to get an SSL Certificate from a SSL Certificate Provider, aka. Certification Authority.

How SSL connection works

The following diagram shows how data is transferred through an SSL connection.

How SSL works
How SSL works (Source: Exabytes)
  1. A user access a HTTPS website
  2. User’s browser requests a secure SSL connection from the server
  3. The server responds with a valid SSL certificate
  4. The secure connection is now established
  5. Data is encrypted and transferred

How can I tell if a website has SSL connection?

The use of an SSL Certificate on a website is usually indicated by a padlock icon on web browsers and the website address will show HTTPS. In some cases, a green address bar is shown.

If a SSL certificate is not recognized by the browser (or it does not pass certain checks), the browser will display a warning to the visitor.
