I may use my personal computer (not a laptop) for work when working from home. I live in germany and signed an agreement that I follow certain security standards. All work data is on a fully encrypted drive, the computer is locked when not used, AV is up-to-date. I would not want to use my work laptop because my own PC is so much faster and already connected to my screens so I don't have to use a KVM and can use all the tools and hotkeys I'm used to without having to synchronize settings. Whenever I have to use my work laptop I want to cry because it's so slow. But I do acknowledge that it's a risk for the company and am actually surprised they allow it at all.
