The launch of Microsoft Exchange Server 2007 has given rise to the widespread use of Subject Alternative Names (SANs) in a single SSL certificate to protect multiple host names.Geotrust’s True BusinessID Multidomain., the most trusted provider of enterprise-class high-assurance SSL certificates, has pioneered the use of SANs to add even more cost-effective, convenient and secure features to its SSL certificates, particularly its Unified Communications (UC) and WildCard digital certificates.
SAN Certificates can secure multiple fully qualified domain names with a single certificate. SAN Certificates are often needed to secure Exchange 2007 Server or Office Communications Server 2007 and in instances where you need to secure multiple domains that resolve to a single IP address (such as in a shared hosting environment).
We are going to talk about two particular products GeoTrust True BusinessID Multi Domain Certificate and Digicert Unified Communications Certificates.
GeoTrust True BusinessID Multi Domain Certificate
With a GeoTrust True BusinessID Multi-Domain certificate, you can add, edit, or delete up to 25 domain names over the lifetime of the certificate. Designed for Microsoft Exchange or Microsoft Communications Servers, this Unified Communications Certificate is also ideal for shared hosting environments, QA testing environments, and small businesses with multiple business applications to secure on a single server.
GeoTrust fully authenticates your organization and your primary domain to quickly issue your certificate. You can add, edit or delete any additional domain names to the subject alt name (SAN) field during the enrollment process or at anytime during the lifecycle of the certificate. True BusinessID Multi-Domain certificates support several domain formats as long as the organization specified in the certificate has the right to use the domain.
GeoTrust helps you protect sensitive information during transmission when your customers, business partners, and employees connect with you online. True BusinessID Multi-Domain certificates enable up to 256-bit encryption, depending on the client browser capability and the cipher suite installed on your Web server.
Grow your business with the True Site Seal
Every True BusinessID certificate includes a dynamic GeoTrust True Site Seal with your company name and a real-time date/time stamp. When users of your online services see the seal and verify your name, they will have more confidence to complete their transactions and trust your services.
