Find the best free firewall for Windows to protect your PC
Firewall history goes back to the 90s when multiple security fails were detected in the first Windows versions. These vulnerabilities in Windows forced experts to work on the creation of an application capable of protecting the system by blocking malicious or unwanted traffic from the network. Thus the Windows firewall was born as a defense for networks and computers. However, for many experts, the Windows firewall hasn't met the expectations of a robust barrier against intruders. For this reason, several developers have created their own versions of free firewall to protect systems and networks from cyber-attacks. In case you are looking for the best free firewall to protect your computer or infrastructure, take a look at the following options regardless of what Windows version you have.
Are you bothered by the pop-up windows that appear every minute with notifications from your firewall? Forget about this with Tiny Wall.

Tiny Wall is so light that only needs 1 MB of HD space.
Tiny Wall aims to improve the security of Windows Firewall itself through a simple configuration that does not require an expert. Its whitelist features allow applications to connect safely to the Internet, reducing the risk of intrusion. You can control Tiny Wall through hotkeys.
Although it does not have the simplicity of Tiny Wall, Zone Alarm was one of the pioneers in the firewalls world. Actually, many considered as one of the must-have applications and best free firewall.
Throughout the years, Zone Alarm has been adding new functions.
