Most e-commerce Website owners, CFOs, CTOs and IT Administrators know exactly what DV, OV and EV SSL Certificates are. But do you know what a Wildcard, an MDC or an SAN/UCC SSL is? Or the advantage each one affords you, and why? Let’s find out.

A Wildcard SSL can be of great use to a company or organization that wishes to display its umbrella entity and more specific subdivisions on separate Websites. This is especially true when this company or organization wants to economize on the cost of the SSL Certificates they purchase to secure them all. Take, for instance, the John Doe Fashion Empire. This hypothetical corporation requires both a corporate primary domain Website and numerous sub-domain Websites to cover its various fashion divisions. By purchasing a Wildcard SSL Certificate, for only about twice the cost of one typical DV SSL Cert, rpl process John Doe’s CTO can secure not only, but also,,, and It’s the perfect merger of security and economy.

MDC stands for Multi-Domain Certificate. And an MDC SSL can be of even greater use to a company or organization than a Wildcard SSL. If a multi-national corporation had a corporate umbrella Website, numerous separate division Websites and even a number of separate geographic Websites to secure, an MDC SSL Certificate would be ideal. This is true especially if the total number of Websites to secure is up to over the maximum of 100. Let’s use the John Doe Fashion Empire as our example once again. By purchasing one MDC SSL Certificate, for only 23% to 93% of what it would cost to buy individual DV, OV or EV SSL Certs for each of John Doe’s Websites, the corporation’s CTO can secure up to 100 Websites with one MDC SSL. These 100 can include the same Primary Domain Website named above, plus scores of Sub-Domain Websites like the ones named above, as well as scores of Top Level Domains such as (the corporation’s British Division), (the corporation’s Japanese Division), (the corporation’s Indian Division), etc. Making an MDC SSL ideal for an international corporation.

SAN/UCC stands for Subject Alternative Name / United Communications Certificate. And an SAN/UCC SSL is another certificate that can come in very handy if you’re the CTO of a large company. An SAN/UCC is a special OV SSL Certificate that has been designed specifically for the Microsoft Exchange Server 2007 & 2010, the Office Communications Server 2007 and the Lync Server 2010. It can secure three to one hundred Websites that can be described as a Primary Domain plus either or both Sub-Domains and Top Level Domains. Yet, outstanding Certificate Authorities offer you the SAN/UCC SSL at a price that is merely 20% to 95% of the cost you’d incur if you purchased a separate OV SSL for each domain you wished to secure. Any company using one of the servers mentioned above, that must secure a Primary Doman, plus scores of Sub-Domains, plus many Top Level Domains, should look into a SAN/UCC SSL.
