TruSecure Corporation offers certification (Score 1)

Take a look at TruSecure. They offer certification of business networks. They have a number of big companies. We use them and it's a great way to look at security. Instead of just looking at what the vulnerabilies are, TruSecure looks at your entire org and network based on their essential practices and then puts you on a process to make your security very good based on layered control. It's a very sane approach to security, since it focus on an continous program and is vendor netural!
