True BusinessID Wildcard is a good solution if you need to secure multiple fully qualified domains that reside on the same physical server and share the same second level domain name. 

For example, if you need to secure the following Web sites:

• www.yourdomain.com
• secure.yourdomain.com
• product.yourdomain.com
• info.yourdomain.com
• download.yourdomain.com
• anything.yourdomain.com

and, all of these Web sites are hosted on the same server box, you can purchase and install one Wildcard Certificate issued to *.yourdomain.com to secure all these sites. The number of sub domains that you can use the Wildcard Certificate to secure is unlimited, for example, the same certificate can be used every time you add a new sub domain to yourdomain.com. If you need to span the wildcard certificate across multiple physical servers, you may purchase additional licenses. 

True BusinessID Wildcard Certificates enable up to 256-bit encryption (depending on your client's browser capability and the cipher suite installed on your Web server) and authenticate the identity of your organization.
