Digging around their site to see how the current product works, it looks like there's separate software installed. It appears they have taken an approach to this product that integrates using Munki, with a separate update application/agent that handles the updates themselves, rather than trying to use MDM, which the app catalog has shown may not be the best strategy or tool for the job.
I personally don't mind this approach if it's expanded in some way to Jamf Pro. Munki is a great tool, and the only reason I don't use it is lack of official support from a vendor, and the manual work required to integrate it into Jamf. It looks like datajar handled this integration and configuration on their own, as a service which could be the appeal in Jamf purchasing them.
