A reliable firewall is a critical aspect of any security initiative. We maintain partnerships with the industrys premier firewall manufacturers, including SonicWall, Check Point, and Cisco. Our consultants will assist you in selecting and implementing the firewall that makes the most sense for your organization. Basically, a firewall examines each network packet to determine whether or not to forward it toward its destination. A firewall also includes or works with a proxy server that makes network requests on behalf of workstation users.
There are a number of firewall screening methods. A simple one is to screen requests to make sure they come from acceptable (previously identified) domain name and Internet Protocol addresses. The most effective firewall implementation is Stateful Packet Inspection. For mobile users, firewalls allow remote access into the private network by the use of secure logon procedures and authentication certificates (VPN).
