Server Certificates

UW-Madison is a participant in the InCommon Certificate Service, which entitles campus staff to unlimited server (SSL) certificates at no cost. The InCommon certificate service is paid for and managed by IT Security. In addition, DoIT offers personal digital certificates (UW Digital IDs) for signing and encrypting email, as well as certificate authentication.

GeoTrust certificates issued prior to November 2010 will continue to work. Customers can replace them with InCommon/Comodo certificates, before their certificate expires.

Please note, the Office of Cybersecurity can issue certificates for only those servers under the wisc.edu, wisconsin.edu, and uwsa.edu domains. It is possible that the Office of Cybersecurity can issue certificates for other domains if UW-Madison is the administrative manager for that domain. Please contact the Office of Cybersecurity to discuss. Alternatively, certificates can be purchased directly from another commercial certificate authority.

SSL Certificate Ordering Information

The InCommon certificate service includes several different certificate types. We can issue single domain, multiple domain, extended validation and wildcard certs as well as a few others. Information on all certificate types and their purpose is documented in the KB article SSL Certificate Types.

Steps for Ordering a Server Certificate

All InCommon/Comodo server certificates are delivered via email from Comodo (cert-manager.com). Please make sure to set any spam filters as appropriate.

Step 1

Decide on the certificate type you need and generate a Certificates Signing Request (CSR). The CSR is used as input for the certificate to be generated.

  • Refer to your product documentation on how to generate a CSR.

Step 2

Step 3
