4 Main SSL Types

There are multiple types of SSL certificates you can choose from to enhance the security of your site and protect your visitors’ or customers’ information. In below, we have listed the main information about shared SSL certificate, private SSL certificate, company SSL validated certificate and extended validation SSL certificate to help you know more about them and choose the most suitable type.

Shared Certificate

Most web hosting companies have integrated free shared SSL with their shared and reseller hosting packages. In this way, you have the ability to enjoy the encryption without spending any money in buying your own SSL certificates. However, because the certificate is free, it does not support you to use your own domain name. Therefore, you have to use “https://secure###.servername.com” to replace your own domain name to avoid browser warnings.

Thus, shared SSL is not suitable for websites, because the warnings may make site visitors think the site is not worthy of trust.

Private Certificate

Being different with shared SSL, private SSL requires you to buy your own certificate, together with a dedicated IP address to run the SSL. Unquestionable, the private one is more money-consuming than the shared one. However, it allows you to use your own domain name and be far away from the warnings in browsers, because the certificate is tied for your domain name. Generally, the URL link you are bound to get is like this: https://www.yourdomainname.com/ without the name of your web server included.

Here, it is worth noting that if your web host doesn’t offer free private SSL certificate, you need to purchase one from a reputed and trustworthy SSL provider. The related information is displayed in the bottom of this post.

Company Validated Certificate

Company validated SSL certificate and private SSL certificate share some similarities. However, if you choose the former kind, you have to provide some additional documentation to certify the identity of your company.

Extended validated certificates verify the identities of companies to prevent fraud by doing a series of checks and validations. By using extended validated certificates on your sites, your visitors will see a green address bar when they visit your site in secure mode. The bar indicates that your site is with the highest level of security.
