Got the ideas from networkchuck

That's historically how east-west would be mediated within an enterprise environment for devices incapable of being secured with agents.

Absolutely, and I've implemented similar east-west controls (as either prevent-first or for detection). You'll get no argument from me on that. I'm just noting an interesting trend as IoT devices become more ubiquitous in commercial and industrial environments, and some of those devices must (for whatever reason) have access to some part of the network or internet.
