Yes, private label CAs are available under our agreement with Comodo. Intermediate CAs hosted by Comodo, but with campus-specific profiles and practice statements, are available to members who desire this functionality for an additional cost.  The fees for this service are $3500 for the first year and $2400 in subsequent years.

InCommon does not offer intermediate CAs hosted by members or third parties other than Comodo.
