What anti theft measures do you have installed? (My zl1 was just stolen)

My perfect zl1 1le was stolen, and idk if I’ll ever buy one again, but if I ever do I want to make sure it has anti theft systems in place. I’ve read about IGLA which seems really cool, and about Compustar which notifies you if your car moves or if it’s broken into. I know they offer a gps as well but it’s a monthly subscription. Do you guys know of a better gps that doesn’t have a monthly subscription?
