Firewalls are programs located at a network gateway server, that protects the resources of a private network from users from other networks. An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling what outside resources its own users have access to.
A firewall, working closely with a router program, examines each network packet to determine whether to forward it toward its destination. Firewalls also include or work with proxy servers that make network requests on behalf of workstation users. They are often installed in a specially designated computer separate from the rest of the network so that no incoming request can get directly at private network resources.
Security Brigade offers the following Firewall devices:
3Com® Unified Security Platform: delivers unprecedented threat protection— safeguarding the network from attacks and misuse, and helping prevent business disruptions, revenue loss and damage to an organisation's reputation caused by security breaches.
3Com® Embedded Firewall: solution adds a critical layer of centrally managed, tamper-resistant protection against network attacks and unauthorized access. The 3Com® Embedded Firewall solution extends centrally managed, hardware-enforced security to notebooks, desktops, and servers across the organisation—inside and outside the network perimeter. This innovative combination of policy server software and firewall card hardware safeguards network assets with superior tamper-resistance that software-only firewalls can't match.
The 3Com® Switch 8800 Firewall Module: is an affordable stateful security firewall designed to protect enterprises from attacks originating inside and outside of their networks.

Avira Premium Security Suite: does a great job of detecting malicious software--arguably a security suite's most important task. But it doesn't do much else. Its firewall didn't completely protect our Vista test PC, for example, and the suite entirely lacks such features as Web antiphishing measures and parental controls.
AVG Internet Security: provides comprehensive real-time protection against online threats.
AVG Internet Security Network Edition: provides centrally controlled comprehensive protection for networks.
AVG Internet Security SBS Edition: can be used in other instances for protection, other than just for MS SBS Servers. If your customer's network setup includes File servers, an Email server and workstations then it is advantageous to choose the AVG SBS Edition as it covers all of them with AVG protection.
AVG Anti-virus Network Edition: provides centrally controlled virus and spyware protection for networks and e-mail servers.
AVG Anti-virus plus Firewall: provides fast, reliable protection against viruses, spyware, rootkits, hackers and poisoned websites.
AVG Anti-virus SBS Edition: provides centrally controlled virus and spyware protection for networks and e-mail servers.
