None of those companies are paying recent grads 200K. Even their more senior folks (non-partners) will not be making the big money. The guys with the experience and the credentials will be making 200K+ but they will be with small boutique consulting firms.
Very Very few folks who are not consultants will be making that kind of money. Companies will bring in the expertise when they need it but won't pay an employee that well.
I know this because I've been doing IAM/Security consulting for over 20 years. I know what I have to pay for talented resources.
