Suppose I buy an iPhone from Apple, and load up a work profile on it. I need to trust that Apple doesn’t give my personal data to the employer profile, and my employer doesn’t have a zero-day to circumvent those controls. I also need to trust that the phone company (or my VPN) provider doesn’t give my browsing history to my employer. I’m pretty comfortable with all of those assumptions. Now instead suppose my employer gives me an iPhone with a cell plan they are paying for. Now there are more questions - is this a vanilla iPhone or is some kind of tracking software installed on it? Perhaps the phone company will freely give up my browsing history to my employer? I’m a lot less comfortable with this. It feels like my employer has legal authority and technical capability to see a lot of what I’m doing on the phone. Edit: > Also don't do activities on them that are... criminal. I’d not worried that employer would get me in trouble with the government for criminal activity. My behavior is a little more constrained by worries that somebody at company could be analyzing my browsing history for violations of company policy, which in a worst-case scenario could get me terminated or cause me to face civil litigation, especially if I were to do a startup.
