I see that you updated your community profile as recommended. There you mention that you’re looking for alternatives too, and in the presentation topic, you specify your preference for on-premise. For this case, I recommend to have a look in the topic with pause announcement for active development of HDS . There, other Spiceheads have reported which solutions they have chosen. Some of these are cloud based while others are on-premise.

I worked as system integrator and system tester for a supplier and manufacturer of industrial control systems, in a department for a highly regulated business domain, typically of national critical infrastructures, regardless of Nation, more than a decade ago. The systems we tested were not authorized to have Internet access and didn’t need such access. In such an environment, HDS would not be an option neither as it would require Internet access for some features too. I didn’t test if and how HDS would work if isolated of Internet.

Some Spiceheads work in organizations regulated by HIPAA. And all currently supported editions of Spiceworks clearly state to not be compliant with HIPAA regulation. So if you don’t want your data at Cloud, then you have some overlap with Spiceheads of such organizations.
