What is a firewall?

A firewall is software that helps your system to monitor your online activity and prevent intrusions and attacks.

Essentially, firewall security helps you to filter network data that come and go from your PC and thus protect the system against internet threats.

The main purpose of firewall tools is to differentiate secured traffic sources from dangerous ones and detect viruses or malware before affecting the system.

The firewall security was created a long time ago in order to examine network packets transferred between different computers.

How does a Firewall work?

This vital service analyzes incoming traffic from the web and determines suspicious websites in order to prevent digital attacks.

A firewall also protects traffic at a computer’s entry point and determines what information is allowed for specific ports on your computer.

In addition, the packet sniffing firewall is the most common type and it practically analyzes packets and determines what is allowed and denied according to the configured security rules.

Thus, using firewall software you provide additional protection for your PC against malicious websites or programs installed on your system.

There are many types of firewalls you can use to better protect your Windows 10 or 11 PC. To name a few, next-generation firewall (NGFW), proxy firewalls, or network address translation (NAT) firewalls. Each of them brings additional features to traditional firewalls.
