Subject Alternative Names (SAN)
SAN Certificates for Simplified Security
What is SAN and Unified Communications?
Certificates that use Subject Alternative Names (SAN) are powerful tools that you can use to secure multiple domain names inexpensively and efficiently. A Thawte certificate with SAN is ideal for shared hosting or QA testing environments, as well as small and medium sized businesses that need to secure multiple business applications on a single server.
Certificates that use SAN can also be referred to as Unified Communications (UC) certificates and are often used for Unified Communications (UC) to secure Microsoft Exchange/ Lync Server, Office Communications Server, or Mobile Device Manager.
Thawte is a recognized Unified Communications certificate partner with Microsoft.

Why do I need SAN?
Instead of purchasing individual certificates for each domain name, you can add domain names in SAN fields to the same certificate. This saves your company the cost of purchasing individual certificates as well the time spent managing multiple certificates.
SSL Web Server with EV and SSL Web Server: add SAN to secure 24 additional domain names on a single certificate. For example, you can add mycompany.com and mybusiness.com to you certificate for domain.com
SSL123 Certificate: add SAN to secure 24 additional same level, sub-domain names on a single certificate. For example, you can add mail.domain.com and payments.domain.com to you certificate for domain.com
What is the difference between a SAN certificate and a Wildcard certificate?
With a wildcard certificate, you can secure multiple sub-domains with a single unique root domain. For example, if you have a wildcard certificate for www.mycompany.com, it will also secure intranet.mycompany.com and email.mycompany.com with the same certificate.
Combining your wildcard certificate with SAN allows you to secure additional domains or multi-level subdomains.
SSL Web Server Wildcard: add SAN to secure 24 additional domain names as well as unlimited sub-domains on a single certificate.
For example, you can add mycompany.com and products.ecommerce.enroll.domain.com as SANs to your wildcard certificate for *.domain.com, which will also protect standard wildcard subdomains such as mail.domain.com and payments.domain.com
SSL123 Wildcard: add SAN to secure 24 additional different level sub-domains as well as unlimited same-level, sub-domains on a single certificate.
For example, you can add campaign1.marketing.domain.com, products.ecommerce.enroll.domain.com as SANs to your wildcard certificate for *.domainexample.com, which will also protect standard wildcard subdomains such as mail.domain.com and payments.domain.com
