My company will scan our computers every once in a while. I've gotten alerts about having software I have installed that I should not - both cases we had an enterprise license and I was using a trial. I didnt want to go through a burdensome request process to try something.

This is a common thing in many larger corporations. Some even lock down machines quite a lot. I have seen multiple cases where this lead to laptops for dev work which weren't connected to the company's network.

There is a list of pre-approved apps, and a method to request approval if it is not on the list. Also, there is a list of approved licenses for open source software.
