The SSL certificate, a now mainstream online feature

First created in 1994, the SSL (Secure Sockets Layer) Certificate was initially only used on e-commerce and banking websites. Nowadays, obtaining an SSL certificate has been made trivially simple. For that reason, it is being used by the vast majority of the websites you visit on a daily basis. You may identify the presence of an SSL certificate on a website at a glance, by simply looking right next to the address bar in your web browser. If you see the “https” prefix instead of the older “http” as well as a lock icon, you know the page you’re currently visiting is protected by a valid SSL certificate.

Why do I need an SSL certificate for my website?

Having an SSL certificate ensures that any data sent from a user to your server or the other way around is being properly secured thanks to the use of public-key cryptography. What this means, is that any piece of information being transferred in this fashion is made protected from any entity attempting to steal it or edit it.

Furthermore, the SSL certificate should be used on absolutely any type of website, including personal homepages, as it is such an omnipresent feature of the modern internet. Your website will appear to be more trustworthy to your visitors, putting you a level above more amateurish projects.

What are the different SSL certificate types?

Https certificates exist under three main types designed for different use cases. Our solutions are designed to adapt to your needs and your degree of expertise.

Standard SSL Certificate

The Standard SSL Certificate is our simplest option. You may create it for free if you subscribe to one of Gandi’s Simple Hosting offers. This certificate can be generated using our intuitive interface and will be renewed automatically by our system before its expiration date. What this means, is that you will be able to enjoy increased safety and a higher level of trust from your users without putting in any extra work. Thus, the Standard SSL Certificate is the ideal product for individuals who wish to develop their online presence, whether they’re just getting started or are seasoned web developers.

Professional SSL Certificate

The Professional HTTPS Certificate is only available for business accounts and other similar legal entities. One of its advantages over the Standard SSL Certificate is that it comes with a financial insurance of up to $250,000 that will be paid in the event the certificate fails to provide you with the security it guarantees. The Professional HTTPS Certificate is the ideal option for any business or corporation requiring an additional safety measure toward protecting their users’ confidential data. As an option, you can also protect a domain name and all its subdomains.

"Business" SSL Certificate

The “Business” SSL Certificate is also exclusive to businesses and corporations. This certificate is securely validated by Sectigo. The “Business” SSL Certificate offers you the same level of financial protection as the Professional SSL Certificate, as well as other options such as the ability to protect more than a single domain name. This SSL certificate is perfect for large businesses making use of many servers and domain names.
