Top Advantages of A UC SAN Certificate

When it comes to securing a domain and ensuring any data transmitted from the domain to the server is fully encrypted and safe, the development of SSL (Secure Sockets Layer) technology really made a difference.

Originally developed by Netscape in the mid to late 1990s, it wasn't fully accepted as secure technology until the early part of the 2000s. This was when the United States Government recognized the level of encryption offered with 256 bit data encryption and 2048 bit signatures provided the security needed to transmit even top secret documents.

The typical website doesn't need that level of security, but it is nice to know it is there. In the past, those IT professionals and administrators working with Microsoft Exchange and Office Communications servers didn't have a top SSL/TLS product to use.

Wildcards didn't always work or caused problems and it was too costly to provide individual SSL certificates for each domain and subdomain on the servers. Additionally, there were a lot of additional steps in creating different IPs, generating the Certificate Signing Request, installing the certificates and then binding.

Today, with the UC SAN certificate, also known as the Unified Communication Certificate or UCC, the process is very simple. To understand the advantages of using this SSL/TLS product, it will be important to take a closer look at what it has to offer that is different from the other SSL certificate options available.

Specially Designed

The UC SAN certificate has been designed specifically for use with the Microsoft Exchange and Office Communications servers. It eliminates the issues that were experienced with the Wildcard when using the Office Communications servers and Exchange servers.

Additionally, by working with Microsoft, Comodo and a very small number of other Certificate Authorities were able to create certificates that work with the tools provided in the server. This includes the Certificate Wizard and the AutoDiscover feature, both which are instrumental in saving time and administrative work in generating the Certificate Signing Request, installing the certificate and ensuring it is functioning correctly.

Multiple Domains and Subdomains

With the ability to secure up to 100 domains and subdomains with a single UC SAN certificate this is a very practical tool for a large company using the Microsoft Exchange and Office Communications servers. Of course, the cert will also work with other server platforms as well, but the extra features and functions only work with those Microsoft servers.

The basic package with this SSL/TLS product provides security of three Fully Qualified Domain Names. One will be the primary common name and the others will be listed as Subject Alternative Names. These can include related or unrelated domains and subdomains. Remember that they will all appear on the certificate in the Subject Alternative Name field area, so if it is important to not group sites together as being part of the same company this should be kept in consideration.

It is possible to add up to 100 different domains and subdomains in the Subject Alternative Name field. As the IT administrator, you have control over the SAN field and full SAN control. The SAN names, as of October 31, 2015, cannot be internal names or reserved IPs. This is a standard passed by the CA/B forum and is being followed by all CAs to provide additional security.

We can also re-issues the cert at your request for free at any time during the life of the certificate. We don't just offer this once, but as many times as needed. This is not uncommon when the domains change or are moved throughout your system.

The Cost

The cost of the UC SAN certificate is very reasonable and, if purchased for the three year maximum time, saves you even more in the cost per year. However, these SSL/TLS products also save money in the cost of administrative time spent in generating a Certificate Signing Request and installing and binding certificates if you are not using the UCC option.

Add on the cost and time-saving features of full compatibility with Microsoft Exchange and Office Communications servers and the quality tech support offered by Comodo and you have a winning combination.
