Granted, I’ve never done security for a billionaire CEO, but I worked security (including personal security) for well over a decade. And I can tell you without a doubt there is no security in security. Nothing we do matters, it’s all entirely for show. Now, at that high level CEO security detail type it may be different, but a security job is basically “be the one who call the popo,” and no one I knew in security, save one jackass, ever considered the job worth a damn to do anything over.
