Some required network services were located off-site. It could've been done in a secure way, but don't expect such considerations from the company described above. It's still better than the many XP and Win2000 production machines with the same internet access.

I can't say a lot because of confidentiality, but if you had seen the factory around the time I quit, having a Win10 computer with internet access would've been the least of your concerns. If we had OSHA here, that building would've kept them busy for a week.
