"Not even as just a dumb tether, with VPN thrown in for good measure?"
"How do you use your work device abroad otherwise?"
It's up to my employer to provide all the equipment and services that I need to do my job. If I need a mobile device to provide tethering, that's fine, but it will be a device provided by my employer.
I've adopted this policy from hard experience -- it makes things safer for both myself and my employer, facilitates accountability, and minimizes the possibility of misunderstandings about what I've used my employer's equipment and systems for.
