A firewall is part of a computer network designed to block unauthorized access whilst permitting authorized communications. It is a device or set of devices configured to permit, deny, encrypt, decrypt, or proxy computer traffic between different security domains based upon a set of pre-defined rules.
Firewalls offer comprehensive network protection from online threats, as such their usage is essential to any security minded business. As well as offering protection for your network, a firewall can also be configured to block access to URLs that you do not want employees accessing such as social media sites.
