You already know how important information technology is to your business. You've got a website that pushes your brand and maybe even sells your products; you've got an internal network that connects all of your employees to each other and the documents they need; you've got company email to manage, and maybe a bunch of cellphones and BlackBerrys to keep track of; you've got security cameras, passwords, log-ins and keycards; and you've got employee management systems covering attendance, payroll, benefits and more. If any of these fails, you've also got a big problem.
