is it Safe to run Good for Enterprise on a custom rom? (phone is unrooted) topic

I own an i9300i and i rooted it yesterday and flashed 5.0.2 based rom.

Now when i was trying to install the Good for Enterprise app, the tech team got an error that the phone was rooted or jailbroken.

My question is. Without doing the whole bypass Good For Enterprise root check, is there a way i can safely (legally) run Good For Enterprise on a this phone, after i unroot it while keeping my custom rom on?

Does Good for Enterprise care for Custom Roms as well or just rooted phones?
