UCC Exchange SSL Certificates – Comodo vs. DigiCert vs. GoDaddy

UCC SSL Certificates are used to establish the authenticity of messaging systems such as Microsoft Exchange so that users of these functions can trust the servers involved.

Email systems play a critical role in the business world; more so than phone systems, fax machines and the postal service. Email is in use by over 2.5 billion people and this figure is expected to reach 2.8 billion by 2018. With that in mind, ensuring your email environment is secure is a top priority for your company.

Microsoft Exchange, arguably one of the most well-known and popular email platforms on the market, helps keep users secure through the use of UCC SSL certificates, which encrypt data and prevent hackers from capturing or eavesdropping on email conversations.

UCC SSL Certificates are used to establish the authenticity of messaging systems such as Microsoft Exchange so that users of these functions (and the systems running behind the scenes) can trust the servers involved. Certain Exchange services such as Outlook Web Access, ActiveSync, Exchange Web Services and Outlook Anywhere won’t work without a legitimate and valid exchange SSL certificate. A certificate can even help facilitate secure email client setup, making life easier for users and administrators. Therefore, it’s important to make sure the process is followed correctly and can be completed in rapid fashion (especially when certificates are nearing expiration!)

The concept of certificates is fairly simple, but the certificates themselves and the way they are used can vary in complexity. A basic certificate assigned to a website – Outlook Web Access, for instance – may simply match the website name to prove to visitors that they are connecting to a known and trusted site. A more detailed certificate can have multiple names associated with it (“Subject Alternative Names” is the official term, and this is also called also called a “Unified Communications Certificate” or UCC) in order to permit it to be used on several servers owned by a business.

For instance, may have three email servers:, and Rather than have users connected to each exchange server individually (which would fail if the server in question were down), they can direct traffic to a standard web address: A UCC containing subject alternative names can then be applied to all servers. This kind of SSL certificate can even apply to multiple domains such as, and

UCC SSL Certificate Cost

How much do SSL certificates cost? That can vary based on the complexity of the certificate, the length of time for which it is to be valid, and the certification authority involved. UCC Exchange certificates can be very expensive when numerous names, servers and functions are involved. However, SSL2BUY offers Comodo Multi-Domain SSL certificates for a fraction of what other organizations such as GoDaddy might charge.

Comparing Comodo with GoDaddy

One might expect to pay $149.99 for a one-year exchange server certificate or the $134.99 for a two-year certificate from GoDaddy; a significant price markup. However, the SSL2BUY certificate can be issued just as rapidly as with GoDaddy (15 minutes or less), can secure up to 100 domain/system names (the one-year certificate permits four domain names, but more can be added for $15 each), includes 24/7 technical support and relies upon the same encryption strength as the competition. Unlike GoDaddy, SSL2BUY offers a 30 day 100% money back guarantee.

Comparing Comodo with Digicert

DigiCert’s price for a UCC certificate is even higher than GoDaddy’s – $299 for a one-year certificate and $538 for a two-year certificate (although a per-year cost of $239 for a three-year certificate is listed). Furthermore, DigiCert can only secure 25 host names compared to 100 permitted by Comodo. While DigiCert also offers a 30-day money back guarantee as does SSL2BUY, adding an additional domain name costs $49 compared to $11 with SSL2BUY.
