This article will help you determine which multi-domain SSL Certificate you should get. We have categorized the multi-domain SSL Certificates in 4 groups, and we would recommend you to read about each group and then choose a multi-domain SSL Certificate from the group that meets your preferences best:

  1. Domain validated multi-domain certificates. There are two certificates in this category: PositiveSSL Multi-Domain and SSL UCC DV. These certificates will secure your websites by making it open from a permanent HTTPS link, will display a padlock icon next to the URL bar, and will make your website show as “Secure” in all web and mobile browsers. These multi-domain certificates are the quickest and easiest to get, so as you only have to prove the domain ownership.
  2. Business validated multi-domain certificates & Extended validated multi-domain certificatesYou need to have a registered company to be eligible for a business validated SSL Certificate. Besides the HTTPS link and the padlock icon near your website’s URL, the people who visit your website will be able to see your company name when they search whom the SSL Certificate was issued to, and they will also see your company name and address when they roll over or click on the dynamic site seal which comes with your SSL Certificate and which you can add to your website. This type of certificate is issued within 1-7 days.
  3. Multi-domain Wildcard certificates. These certificates allow you to secure one main domain and multiple wildcard domains using one single SSL Certificate. You can get a PositiveSSL Multi-Domain Wildcard SSL if you want a domain validated SSL, or a Multi-Domain Wildcard SSL if you prefer a business validated certificate.
