Ok.. for clarification is this an additional 'paid' service in order to receive timely 'updates' which are typically bug fixes?

"In ZENworks 11 or later, you need to activate the System Update entitlement to obtain updates to the Novell ZENworks 11 software on a timely basis. You cannot receive new updates if the System Update entitlement is not configured."

I presume updates can still be downloaded via the download site for patches?
