It is not enforced in an enterprise system but in an enterprise environment, not
sure what the criterion for that is (device enrolled?).

Thus I'd suggest:
"enterprise system (like Chrome OS)" --> "enterprise environment (for Chrome OS
only)"

Done.

"Enforced" sounds somewhat negative.  Wouldn't "Programmatic" be nicer?

[fhorschig, 2015/09/07 14:09:34]

Was my first thought, too. Originally, I considered it slightly misleading (as
everything is set by the program) and thought we should indicate that it was a
special case. If you think programmatic is good, I am happy to go with that.
