Computers contain a lot of information that's critical to your business. Sales data, customer data, inventory management, passwords, proprietary data, research projects, business expansion information, competitor's information, to name just a few. You can't afford to be without it and you certainly can't afford for someone else to get their hands on it.
We've had experiences uncovering the disgruntled employee who takes out his anger at being passed over for promotion by hacking into the system and limiting everyone else's access. They have even wiped out financial and client data after changing administration passwords. This is illegal and a big problem for which business pay millions of dollars per year to protect against. The problem is that most law enforcement agencies cannot dedicate the necessary resources to help business prevent these problems.
