Think fast: when you see photos or videos of Tim Cook at a store opening, taking a walk through China (something he has done with a certain frequency) or something like that, can you see any security? Hardly, but that does not mean that the CEO of the most valuable company in the world walks around without protection.
Of course, he is not the President of the United States to need a secret service to accompany all your steps, but it is also not prudent to leave without protection when you run a company the size and importance of Apple.
For analyzing a 14A report that Apple sent SEC (U.S. Securities and Exchange Commission), the site Patently Apple found information that Apple spends almost $ 700k per year in the safety of your boss.
It seems a lot, huh? And it is still, but the Fortune said that Amazon and Oracle, for example, spent $ 1.6 million and $ 1.5 million in 2014 respectively to protect their CEOs (Jeff Bezos and Larry Ellison).
