How to protect your computer for free: Best firewall software

In today’s digital age, protecting your computer from cyber threats is more important than ever. One of the most important components of computer security is a firewall. A firewall acts as a barrier between your computer and potential threats, such as hackers, malware, and viruses. While there are many paid firewall software options, there are also excellent free firewall software that can help you protect your computer without breaking the bank.

What is a firewall?

A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization’s predefined security policies. It acts as a gatekeeper, allowing only authorized traffic to pass while blocking unauthorized or malicious traffic. A firewall can be hardware, software, or a combination of both.

Why do you need a firewall?

Without a firewall, your computer is vulnerable to a wide range of cyber threats. Hackers can exploit unprotected computer systems by gaining unauthorized access, stealing sensitive information, and installing malware. A firewall can help prevent these threats by blocking malicious traffic and keeping your computer safe from potential attacks.
