Firewall

The Internet continues to grow and many companies already have a connection to the world wide network. Together with the advantages of the Internet, the company gets exposed to the drawbacks of a public network: malicious persons might try to gain access to your internal network and steal your company critical data.

With a firewall one tries to make this theft (or other activities) as hard as possible. GNU/Linux is known to be a very secure operating system and thus suitable for firewalling. During the last years the firewalling architecture of GNU/Linux evolved to a state-of-the-art packet filter known as Netfilter.

KEY FEATURES
  • Stateful packet filtering (connection tracking)
  • Enhanced Network Address Translation
  • Quality Of Service
  • Packet Manipulation (eg. TOS-modification)
  • MAC address filtering
  • Rate limiting
All filtering actions happen in kernel space, making the GNU/Linux packet filter far more efficient than some existing commercial products. The excellent firewalling-code is completely modularized which allows developers to continue adding features to it.

Digibel already implements GNU/Linux firewalls since 1996 using the predecessors of the Netfilter architecture and adapted its firewall products each time the technology evolved. The Digibel firewalls incorporate the highest security standards and passed extensive auditing and testing.
