Right... I had my copy of parallels about three months ago and as of yet have not been able to use it because my IT department are very worried about security implications of having an apparently insecure windows OS sitting on top of my Mac OS. IT have refused to give me a Windows 10 product key because of their fear of the windows side of the set up potentially being hacked. So, my primary question is, is this a viable concern? Is this more secure than a standard windows PC because it's sitting on a mac? If so, why? If I am not running parallels, is the security risk that windows apparently poses negated because windows is switched off? Thanks.
