A firewall is a barrier between your companies IT infrastructure and the outside world. No business would operate without locks on its doors nor should it operate without a firewall. Just as a criminal would love to break in to a company to steal its physical assets an experienced hacker would like nothing more to come in and steal your intellectual assets. Many small businesses think that nobody would want to break into their network since they don’t think there would be value to the hacker. This is far from the truth. Many hackers-to-be practice on small businesses to gain experience and cause mischief. A couple of years ago we had a home based client that had trouble just accessing information from one computer to another. Once we arrived we noticed that there was no firewall. There was so much traffic flowing in from the Internet that it completely bogged down their system. Once a firewall was installed everything cleared up and they were able to conduct business as usual.
It is important to talk to an experienced consultant on how you run your business before selecting a firewall. There are many options an experienced engineer would know about and could include in their recommendations. These can range from VPN access to allowing appropriate connections from the outside world in while still keeping the internal network safe. With our experience we can match our business partners with the correct firewall that not only protects their business but enhances it.
