Since no security is absolute, you need a contract with ongoing concern. Perhaps you can have a technician come in once every month to make sure everything is properly updated. Firewall, anti-virus, and encryption are the most important parts of a network, and they work best if set up by a professional.
Your technician should also be able to help you decide just how much security you need. Multiple-layered firewalls can slow you down far too much if you're not careful. By discussing concerns with your computer consulting company, you can decide just how much you need and create ongoing appointments to keep you up to date.
