A firewall is a piece of software or hardware that helps to screen out cyber criminals, hackers, malware and viruses that are trying to reach your computer via the internet. It is a network security device that manages and controls both incoming and outgoing network traffic, deciding whether to allow or block specific traffic based on a defined set of security rules.
Software firewalls are installed on your computer and like most software available, you can customise it. This allows you to have some control over its function and protection features. This will protect your computer from outside attempts to control or gain access your computer, keeping you protected and safe away from potential hackers.
By not having one, you are putting yourself and your computer at a security risk. For more information on Firewalls, please contact us via email or phone at 01329 888444.
