Re: Far beit for me to say....
Companies like AWS and Microsoft hire the best and brightest security people and pay them huge salaries. Ergo, if you think that the systems you run are more secure than the major public clouds, then you must consider yourself a bit of a security genius. However, given that your comments on the topic are about the Sony hack, which had nothing to do with public clouds, your belief in yourself may prove to be unfounded...
