2023 • The Best Free Firewall Software to Fortify Windows PC
When it comes to computer security, we place a lot of emphasis on antivirus. But, there’s one more piece of the pie that we can’t ignore – Firewalls.
A firewall is a barrier that sits between your computer and the Internet. It filters unwanted traffic or activities in order to safeguard your PC against hackers and cyber-criminals.
Windows comes with a perfectly fine built-in firewall. However, a third-party firewall software will make it easy to configure rules and offers better security.
This blog offers an in-depth look into the top free firewall software available for Windows PC, guiding you through their key features and benefits. Our aim is to provide clarity and insight, ensuring you choose the firewall most suited to your needs and expertise level.
Did You Know? Did you know that the term “firewall” originally referred to a wall constructed to halt the spread of fire within a building. In the digital world, it prevents the “spread” of cyber threats!
