I was recently sponsored by my employer to do a professional certification which involved an online e-proctored exam. I was asked to install the e-proctoring software on my personal computer, because corporate security policy does not allow unvetted 3rd party software onto company devices. I told my employer that's my policy too, and that I would need to be supplied with a separate laptop if they wanted me to take the exam. They did.

I think if universities want to mandate use of e-proctoring software, they need to provide temporary/burner devices too.
