In computing, a firewall is a piece of hardware and/or software which functions in a networked environment to prevent some communications forbidden by the security policy. A firewall has the basic task of controlling traffic between different zones of trust. Typical zones of trust include the Internet (a zone with no trust) and an internal network (a zone with high trust). The ultimate goal is to provide controlled connectivity between zones of differing trust levels through the enforcement of a security policy and connectivity model based on the least privilege principle.

Firewalls are one of the best ways to protect your computer from security threats.

A software store may have gotten surplus copies of firewall software or wish to reduce their firewall inventory due to an updated version and will sell new copies of firewalls at a reduced cost. Before you bid on an auction, make sure that the firewall product says the product is "new and in a retail box".
