Inexpensive units, usually under $100, can be purchased from Linksys, D-Link and Netgear. These units are aimed at the home/home office users, in other words, easy setup and limited features. More expensive hardware can be found at Sonic Wall, Watchguard and Fortinet. These units can range from $1000 to a few thousand, depending on the features required. Ethernetworks can help you decide which best fits your business and what services you need to run for optimum security. If you don't have the qualified personnel or the time to spare, we'll pick up the right unit, install and configure it for you. Should you desire a fully customized firewall, we'll build one to suit your specific needs using IPtables/Linux, Snort and other open source tools. The hardware requirement for this type of application is your standard X86 PC with sufficient RAM. In other words, if you have an extra PC laying around not being used, you're in business.
