FAQ for Wildcard SSL Certificates

What is a Wildcard SSL?

An SSL certificate is bound to the server and the FQDN of the website to be encrypted. This requires one certificate per FQDN. If the common name in the SSL certificate does not match the FQDN, the browser reports an error.

Many companies have structured their online presence so that they have a main domain, such as as well as a number of subdomains such as e.g. and Each subdomain requires a separate certificate.

Wildcard SSL gives the advantage of encrypting an unlimited number of sub-domains (and servers) with one certificate.

Where can wildcard certificates be used?

The use of sub-domains is unlimited: Mail servers, FTP servers, member areas, etc. Each sub-domain is often its own website - with wildcard certificates you can avoid the time-consuming task of managing multiple certificates. A regular or single domain SSL certificate secures the base domain, but not any of its sub-domains making in many cases a Wildcard SSL an ideal solution.

How does a wildcard SSL certificate work?

Ordering and installing a Wildcard SSL certificate is not different from other certificates. The main difference is that when you create the Certificate Signing Request (CSR), you place a star at the subdomain level, which means * is the common name. This means that you encrypt any sub-domain at that level of your URL. * then can encrypt,, - and also

Which types of Wildcard SSL are available?

Wildcard SSL Certificates are available in 2 validation classes: Organizational-validated with validation and registration of the organization name for higher trustworthiness. Or domain-validated without validation and without registration of the organization name. Wildcard SSL Certificates are not available with the validation level "Extended Validation" (EV). The CAB Forum, the responsible authority for the EV standard, has decided that the FQDNs must be present for EV SSL, which is not the case with Wildcard SSL.

Can Wildcard SSL be combined with Multi-Domain SSL?

Can Wildcard SSL be used for Microsoft Exchange?

When planning a UCC and Exchange environment, the question often arises as to whether the FQDNs should be secured with a Unified Communications certificate, or possibly with a wildcard SSL.

What speaks against the use of Wildcard SSL?

Wildcard SSL can only encrypt one sub-domain level. If several sub-domain levels are to be encrypted, a separate wildcard SSL is required for each sub-domain level. Or a certificate that contains several wildcard domains.

If your sub-domains are administrated by different entities, each entity requires the Wildcard SSL certificate together with the private key. The Private key needs be treated with confidentially, and it is therefore important that it is handled and transferred carefully.

If you are using only one copy of a Wildcard SSL with only one private key company-wide, a re-issuance and new installations of the certificate on the web servers becomes necessary in case the private key gets compromised. Confidential handling of the private key is therefore crucial.
