A computer network firewall is an electronic blocking mechanism that will not allow unauthorized intruders into a computer system. A computer firewall is a software program that blocks potential hackers from your individual computer or your computer network. Many different computer firewall software packages are available with a broad variety of costs and update options. Any computer that is always connected to the internet needs a firewall package.

Linux System Solutions offers firewall, intrusion protection, virus protection, spam protection, VPN gateway, and URL filtering capabilities. A unified management platform makes it easy to administer, maintain and update a complete network security solution for an affordable price.

Linux System Solutions work to understand how a network is used and that's the time we design and implement the security to protect the whole network. The design for the Linux Firewall Server can evolve as the company changes with security and services to meet the needs.

• VPN - Secure remote access that encrypts data between the main office and a remote network or computer.

• Bandwidth Monitoring - this add-on gives text & graphic information on how connectivity resources are used.

• Web Caching - Can save up to 40% of the network's bandwidth by caching frequently visited web sites.

• Web Blocking - Allows the firewall to block traffic to many sites that are cause for concern or liability.

• DMZ Network - A DMZ network is a second network behind the firewall used for services that need to be accessed directly from the Internet, such as mail or web services. The DMZ network is still protected by your firewall. Basically, the private network can access the Internet and the services on the DMZ, but the servers on the DMZ and requests from the Internet cannot reach the private network.
