My thoughts on this(for what they are worth - which is not much)....,Redgeek....if you are truly a geek then you would not be asking us this question.....you would be TELLING us how it would be done.
Secondly, if you had a company and needed to prevent security breaches, I am sure you would employ someone to advise you.
After all your security is paramount to continuing a successful business.

As you are relatively new on here,this may sound harsh and unwelcoming.
It isn't meant to. It is meant to let you know that you are asking the wrong people these questions, and that relying on, or even taking notice of our answers is stopping you from effectively seeking a solution to your perceived problem.
This is the wrong bush to look under.
