Use Subject Alternative Names (SANs) to Secure Your Entire Environment

UCC certificates give you maximum flexibility over your SANs.

Unified communications (UC) certificates (also called SAN certificates) use Subject Alternative Names to secure up to 25 domains, sites, and subdomains with one certificate. Four domains are included in the base price of the UC certificate, but additional names can be purchased.

For example, with a UC certificate you can secure

  • www.example.com
  • www.example2.com
  • www.example3.net
  • mail.example.net
  • dev.example2.com

This makes UC certificates perfect for Exchange/OCS environments or any environment where you need to secure multiple names across different domains.

For an easy way to find all the certificates on your network, use our free SSL Certificate Discovery Tool.

3 Years $239 per year Includes 4 names, additional $89 each
2 Years $269 per year Includes 4 names, additional $69 each
1 Year $299 Includes 4 names, additional $39 each

Unlimited Server License

Most other Certificate Authorities' SSL Certificates (including wildcard certificates) are only licensed for one physical server. But with DigiCert's unlimited server license, you can use your certificate on as many servers as you want. You can even generate separate certificates with unique key pairs for each server. That's the ultimate in flexibility.

You can use a UC certificate to run multiple services (like OWA, SMTP, Autodiscovery, ActiveSync, and Outlook Anywhere) on one IP address.

EXAMPLE #1
1. www.example.com $299 USD (1-year base price)
2. autodiscover.example.com $0 USD (included in base price)
3. mail.example.com $0 USD (included in base price)
4. other.example.com $0 USD (included in base price)
TOTAL $299 USD

Or you can add an additional name to secure a total of 5 sites.

EXAMPLE #2
1. www.example.com $299 USD (1-year base price)
2. forum.example.com $0 USD (included in base price)
3. other.example.com $0 USD (included in base price)
4. www.example2.net $0 USD (included in base price)
5. secure.example3.org $39 USD (additional name price)
TOTAL $338 USD

State-of-the-Art Data Encryption

One of the best ways to protect your website from brute force attacks is to use 256-bit encryption along with 2048-bit root certificates. This hybrid cryptosystem benefits from the best features of both symmetric and asymmetric encryption. DigiCert certificates use the most secure encryption available and support for both SHA-1 and SHA-2 algorithms.

Complete Flexibility

One of the primary benefits of DigiCert Unified Communications Certificates is the complete control you gain over the Subject Alternative Name field, allowing you to secure up to 25 host names with just one SSL Certificate. For instance, with one UCC Certificate you can secure multiple services (OWA, SMTP, Autodiscovery, ActiveSync, and Outlook Anywhere) in Exchange 2007 or 2010. Running all services on one IP address greatly reduces the complexity of your server configuration and simplifies management. Additionally, you have the flexibility to add, change, and delete any of the SANs on-the-fly to reflect the evolving needs of your network.

 

Simplified Maintenance

Save time and money by not having to purchase and manage multiple certificates and expiration dates. With a DigiCert UC certificate you can secure multiple sites, IP addresses, servers, and domains with a SINGLE certificate. You don’t have to put multiple IP addresses on your server and assign a different certificate to each address.

Unlimited Server License

Most other SSL Certificates are only licensed for one physical server. But with DigiCert's unlimited server license, you can use your UC certificate on as many servers, IP addresses, and domains as you want. You can even generate separate certificates with unique key pairs for each server.
