Best Firewall Products for Windows: Top-8 Solutions

Firewalll for Windows

When it comes to online protection, having a reliable antivirus is vital. A useful addition to antivirus software is a firewall, which is commonly described as a virtual shield that stops all types of cyber attacks before they reach your computer. When combined with modern antimalware, a firewall provides protection from unauthorized success to the system.

You may not be aware of it, but most Wi-Fi routers come with a so-called hardware firewall, which protects the entire home network at the root. Moreover, if you use Windows 10 OS, you also have a built-in firewall that comes as part of the Windows Defender tool integrated into the system.

Both solutions are good but not flawless. That’s why it’s a good idea to have a new dedicated firewall app. In our guide, we’ll review the best home firewall products to use in 2019.

How a Firewall Protects Us from Cyber Attacks

To understand the mechanism of action of a firewall, try to imagine a powerful filter that is placed between your computer and the rest of the Internet. It analyzes all the incoming and outgoing data and either lets it through or not. It works in both directions, which, on the one hand, prevents the leakage of sensitive data, and on the other hand, protects from cyber threats penetration.

In particular, firewall effectively stops the following types of threats:

  • Transferring your data to third parties by some apps that can be installed on your PC.
  • Hacker attacks that can destroy the system if not neutralized timely.
  • Viruses, worms, Trojans, and other forms of malware.

No surprise firewall products are in demand in the software market. You’ll find dozens of both free and paid solutions not only for Windows 10 but for other operating systems as well. Keep on reading to find out about the best firewall tools available in 2019.

Is Windows Firewall Good Enough?

Before we proceed to review third-party software, let’s make it clear what pros and cons the native Windows 10 Firewall have. In general, both experts and regular users share the view that it is not bad. In other words, it does work, and when combined with a reliable antivirus, it delivers pretty good results.

There are two major complaints about Windows 10 Firewall. From the user’s point of view, it is a sort of incomplete in terms of features. It is less flexible than some third-party products, and its setup is a bit complicated. Also, experts believe that despite recent improvements, Microsoft’s firewall is still vulnerable to some types of threats, such as Trojans. The holes in its security system prevent it from being the number one solution.

8 Top Free Firewalls

Contrary to popular belief, the most expensive firewall is not always the best firewall. More than that, there are some great products available for free. We are glad to introduce you eight top free firewalls to use for home network protection in 2019.

Comodo Free Firewall

That is a flexible and rich in features software for Windows 10, 8, 7, and XP, which is frequently mentioned in expert reviews as the number one firewall in the world. Its database of threats is upgraded automatically, which allows stopping the majority of them before they reach the system.

Comodo uses machine learning to analyze the normal behavior of the system and blocks all non-typical activities as soon as they are detected.

The game mode helps reduce the impact on the system.

Glasswire

Glasswire

Essentially, Glasswire is an add-in for the default Windows Defender tool for Windows 10, rather than a separate firewall. It provides the same level of protection but offers expanded possibilities and a more informative interface.

Instead, you can click on a small icon in the system tray to check the information of new threats (if there are any.)

However, there is the reverse of the coin. While pop-ups can be rather annoying, they are effective, as you are notified about potential threats immediately. In the case with TinyWall, you are risking to miss important notifications, as they are shown on demand only.
