Of course, one cannot expect a free, open-source firewall variant to have the same functions and support services as a paid commercial firewall. On the contrary, especially for administrators who have less experience, open-source firewalls bring great advantages, because they are quicker and easier to set up. In this way, they work quickly and do not compromise the security of the network.

Although our operating systems come with some kind of firewall software, however, they are not enough to protect each device of a network. We need a well-configured Firewall, which is a key component of network security when we are about to expose our internal network to the outside world. In this article, we will discuss some best-known open-source firewalls based on Linux to protect networks and computers from cyber security threats. To save our system from the outside world, we need a dedicated software platform called “Firewall”.
