LANNet Computing Associates specialise in the delivery of quality secure Internet connectivity at affordable cost.

You should consider what a LANNet firewall / router can do for your network.

At LANNet it is our opinion that within the next 12 to 18 months most business will not be able to operate effectively without a permanent connection to the Internet, and this worries us. The Internet is "The Bad Lands" and should only be approached fully armoured against the attacks out there, and that means installing a secure, yet flexible, firewall between the Internet and your precious systems.

You could go out and buy a $50 "off the shelf" firewall to run on your lone PC and it might afford you some protection, or you could buy a $10,000 hardware/software solution in a nice red case that will afford you strong protection. In neither case are you fully aware of what protection is being offered, nor are you aware of what tuning might be necessary to suit your particular requirements. Here at LANNet we have installed many firewalls and in almost every case it was necessary to tailor the design to suit the customer's needs; "off the shelf" firewalls just do not cut it.

What LANNet offer is custom designed firewall software operating on commodity, even legacy, hardware, providing you with the level of security that you need at the price that you can afford.
