What Is It?
A Wildcard SSL Certificate
helps enable SSL encryption on multiple sub-domains using a single certificate
as long as the domains are controlled by the same organization and share
the same second-level domain name. For example, a Wildcard certificate
issued to Company ABC using the Common Name (“*.CompanyABC.com”)
may be used to secure the following domains:
- login.companyabc.com
- payment.companyabc.com
- support.companyabc.com
How VeriSign Can Help
Ask your VeriSign
sales contact about Wildcard SSL Certificates. A common, high-level
standard of security across all types of configurations is better achieved
when you do not share or copy certificates among servers. Limitations
of using Wildcard SSL Certificates include:
- Security: If one
server or sub-domain is compromised, all sub-domains may be compromised.
- Management: If the
wildcard certificate needs to be revoked, all sub-domains will need
a new certificate.
- Compatibility: Wildcard
certificates may not work seamlessly with older server-client configurations.
- Protection: VeriSign
Wildcard SSL Certificates are not protected by NetSure extended warranty.
