Multi-Domain Wildcard SSL Certificates

Multiple Domain SSL (UCC/SAN)

The Subject Alternative Name Certificate (SAN SSL) also called the Unified Communication Certificate (UCC SSL) or the Multi Domain SSL Certificate was particularly developed to secure multiple domains and sometimes subdomains by owning one single SSL certificate. This type of certificate ensures the security for both, your internal and external domains/subdomains and is fully compatible with your Microsoft Exchange products and Microsoft Office Communications Server. UCC/SAN Certificates are not just easy to be managed but are the most cost-effective option. These Multi Domain Certificates give you the opportunity to secure your main domain, for example, ssldragon.com, together with many other totally distinct domains, like ssldragon.net, sslcertificates.com. Some SAN/UCC Certificates also allow you to secure the subdomains that belong to the domain names which you are securing, such as mail.ssldragon.com and account.ssldragon.com. Unlike Wildcard Certificates, UCC/SAN certificates are available in all three validation methods: Domain Validation (DV), Business Validation (BV) and Extended Validation (EV).

Wildcard SSL (One Domain & All Sub-domains)

The Wildcard SSL certificate was specifically designed for ensuring the security of your main domain, along with its multiple subdomains. For instance, if your site’s domain is ssldragon.com, then the Wildcard Certificate for “*.ssldragon.com” will secure an unlimited number of your first-level subdomains like mail.ssldragon.com, account.ssldragon.com or login.ssldragon.com. By buying this SSL certificate, you don’t need to purchase other certificates for each subdomain. The Wildcard Certificate comes in two options: Domain Validation (DV) and Business Validation (BV). Besides being a convenient way of securing your site, Wildcard SSL certificates are very easy to be managed because the domains will have the same renewal date. This is why you should consider getting Wildcard SSL Certificates if you own a complex website, with different subdomains, IP addresses or server storage options. Yet, if you have level 2 subdomains (like test.account.ssldragon.com) or you need an Extended Validation (EV) SSL Certificate, you may have to buy a separate SSL certificate for each domain/subdomain or a UCC/SAN Certificate for all of them.
