Best Personal Firewalls You Should Look For

A firewall is a kind of network security device that helps to monitor incoming and outgoing traffic. It decides whether to permit or block any particular traffic depending on a defined set of security rules.

Setting up a personal firewall is the simplest way to protect one’s home network from any attack. The firewall acts as a barrier between the trusted, secured and controlled internal network and the unreliable outside network.


A firewall protects a network or network device from unauthorized access by averting traffic to or from these systems. Here, we can distinguish firewalls into two types.

Firewalls provided by the OS which are generally installed on the computer by default are also known as host firewalls. For example, the Microsoft Windows system firewall or iptables firewall by Linux systems.

The other type is network firewalls. They are devices placed in the network and are an essential component in the industrial sector, especially when they are linked to additional networks, or wired transmissions are combined with unsecure network technologies.

In such cases, the network firewall sets up the network boundary as the first line of defense against any attack and permits only desired traffic in and out of the network.
