If you have a computer connected to the internet then your computer may be susceptible to an external person (virus or another computer!) gaining access to your system.
A firewall is essentially a device (whether software or hardware) that provides a barrier between your internal computer system and the outside world (the internet) to stop intruders gaining access.
Relatively good firewalls can be setup quite cheaply, so contact us and let us provide you with advice on security for your network. (There may even be some advice that would apply to your existing system to improve security.. for example ensure all your passwords are not easy dictionary words, and if possible combine them with numbers).
