Explained in the simplest terms, if your computer were a house; anti-virus software would protect your doors, and a firewall would protect your windows (normally closed, but can be prised open by someone with malicious intent).
A firewall is essential for every business connected to the Internet, whether it is one or one thousand computers in size.
Small businesses very often use an incorporated firewall on the PC they are using, this can be bought as an add-on or the free embedded firewall included on Windows XP Pro with service pack 2.
We design, configure and install hardware firewalls solutions which sit between your network and the Internet. In doing so, all traffic between the two is scanned and only allowed in or out if it can be proved and trusted.
A firewall will also allow mobile workers and branch offices to connect in seamlessly to your central network for email and other data services.
We consult on solutions from six different firewall manufacturers, suitable for networks of 5 computers upwards.
Firewalls also need to be updated with software from their respective vendors to ensure they know how to identify new attacks from the Internet. SC can keep your firewall up-to-date and also perform period testing to ensure they can detect and prevent an Internet based attack.
