Firewalls draw the line which separates internal and external networks. NetGuards Firewall filters traffic based on IP address, protocol and ports that allow administrators to: 

  • Designate which systems and services (http, ftp, etc.) are publicly available
  • Create a DMZ and perform NAT
  • Run as a transparent bridge to complement existing hardware

The Firewall is the most basic security element to hide your network from the outside and control all external access points (also known as ports). It lets you block unwanted activity and protect your network.You can build a list of rules that meets your unique needs—control traffic by protocol, source address or port, destination address or port, and set default actions.

Firewall evaluates traffic traveling across your network by applying your rules until a block/pass verdict is reached or a default action is taken.
