So the company email and admin software is isolated inside Knox. Alternately isolate your personal browsing and banking inside Knox. Either way you can't even cut and paste between the main Android apps and the Knox apps, they are completely separate.
They say this but it is not true
I helped someone with a locked device copy a whole bunch of stuff before she quit
Oh and also, Knox has already been hacked
In OPs case it is his own device, so it is quite simple to root the phone and do what you want to
