The built-in firewalls that your Windows, Android, Mac, and other OS have are not enough. Here are tested top free firewall programs that you can use.


The firewall monitors the data transmission between your device and network servers. It detects and blocks any suspicious accessing attempt via the internet based on a pre-configured set of rules. Hence, it serves as an efficient protective shield for the devices against hacking and malware attacks. Most operating systems come up with basic built-in firewalls. However, using third-party software for additional security layers and more customizable options is crucial. Luckily, some incredible firewall apps are available today that are free to use and offer unbreakable protection against cyber-attacks.

Many people think the built-in firewall their Windows, Android, iOS, and other operating systems have is enough. However, that is not the case.

But do not worry. You need no extra cash for additional firewall software; there are some of the best free firewalls you can install.

However, before you get your hands on top-notch free firewall programs, it would be best to cover the basics first.

Why do you need a firewall?

A firewall is software or hardware that prevents hackers and certain types of malware from gaining remote access to a computer over the World Wide Web.

Its purpose is to verify information received from the Internet or a local network and block or allow computer access.

The firewall is not the same as an antivirus or anti-malware program.

Firewall programs protect against internet worms and hacker attacks. In contrast, anti-virus programs protect against viruses (as the name suggests), and anti-malware applications shield your device against malicious programs.

You need a firewall if you have a computer connecting to the Internet. It’s as simple as that (given that you value your online projection).

Think of a firewall as a barrier between the data on your computer and the outside world; it is a kind of door lock for your home, office, or vehicle.

Even if you have spyware and anti-virus trackers and keep your computer up to date, someone could still access your information if you do not have a firewall installed.

In its recently conducted study, MaketsandMarkets predicted the market of Network Security Firewalls to grow to 5.3 billion USD by 2024.

No market cannot grow that much without some practical reasons. There are many reasons for the Firewall Market’s growth.

However, most people use firewall protection to safeguard their important data or sensitive information.

And you must understand that you are at high risk of getting your information stolen if you do not have a quality firewall program installed.

Quick Guide: Top 5 free firewall software

  1. Peerblock — This enables you to block the entire list of IPs, is Open Source, and blocks pop-ups and ads from sites.
  2. ZoneAlarm — Boasts anti-phishing and safe document download features and offers free 5G cloud backup.
  3. TinyWall — An entirely free lightweight firewall software with no annoying pop-ups or ads.
  4. Comodo — Offers a fast and hassle-free online experience, blocks all kinds of cyber attacks, and is a go-to product for cybersecurity novices.
  5. Sophos XG Firewall Home Edition — Free home version that supports many other Sophos-backed products and boasts an excellent collection of features.

How? ‘Or’ What?

The question What can people steal from your device? has a lot of answers.

It is important to know how it can happen; let’s cover some ways someone can access your system.

Your password is like your fingerprint on the internet. It allows you to access all your accounts. Hackers can destroy your personal and business life if they can access your password.

These computer jocks have three basic methods of obtaining your password: guessing, brute force, and cracking.

Cracking is the most effective method as the hacker searches for your passwords saved on your computer using high-tech tools. A firewall can prevent them from being able to access these files and your personal data from leakage.

Sometimes, a hacker or hijacker is not interested in stealing your information; they simply want to cause you as much misery as possible.


Because malicious people often do not care about your feelings or data. They just enjoy making others’ life miserable.

Through a DOS (denial of service attack), they can freeze your system to the point that servers, computers, and networks go down.

If that happens, you will lose money and your business reputation.

Imagine what could happen to your business if your client list, sensitive business plans, or trade secrets were available to the world.

It’s not a pretty picture; it’s every businessman’s worst nightmare.

All in all, there are many ways that hackers can use to access your information when your device is connected to the internet.

I have not even explained half of how hackers can make your life miserable; remember that they can defeat your defenses and cause much damage.

That is why you need firewall protection all the time.

How a firewall functions

The firewall is a system that ensures network security by filtering outgoing and incoming network traffic. A firewall filters the traffic based on a set of rules defined by the user.

In general, the function of all firewalls (let it be a complex firewall used by big corporates or a simple personal computer firewall) is only to allow legitimate communication to flow and eliminate or reduce unwanted network communications.

Firewall software types

There are two basic classes of firewalls: client firewalls and firewall computers. These two firewall classes can prevent unwanted access to the computer.

A client firewall is software that resides on the computer itself and monitors all incoming and outgoing network traffic of that device. A firewall computer is a physical device connected between the internet and the computer.

These devices are often used in small network environments where multiple computers must share the same internet connection.

Small routers in many homes and offices often have integrated firewalls. If you use a router, make sure you have a firewall.

Users who physically move (let’s say you go outside even for groceries) should always have a client firewall installed on their device. When we connect to the internet outside the office or home, we cannot take risks – connecting to the internet in public is always dangerous

While antivirus software is an excellent means of protection, deploying firewall security on your device can be the needed hook that leaves the attackers out of combat.

Benefits of firewalls in organizations

Companies that opt for the installation of such a protection system enjoy the following advantages:

Safeguard the company from internal threats

Many times, the enemy is not outside but within the same company.

With a Firewall installed, an organization can block user access to unwanted websites and gain reports on non-productive activity to limit them for its benefit.

Firewalls also allow remote workers more secure access to the company’s network through VPN connections.

Keeping the network safe and functioning properly

Nowadays, companies cannot afford to go down even for a while because the workers mostly use applications hosted in the cloud to perform their job functions.

Intruders who sneak into a company can cause a network crash that a quality firewall could have anticipated and avoided.

Protect corporate data

Firms of all sizes must invest in a business-grade firewall system to protect their data, network, and company security.

The hacking cases continue occurring, and we have witnessed many times that hackers succeeded in stealing data critical for a company’s operation.

Such mischief can be avoided with a firewall so that the loss of information that can seriously undermine a company’s economy should not happen.

How to choose the best free firewall

Admittedly, selecting firewall security software can be a tedious task. Here, we cover three vital aspects to consider before opting for a firewall:

Pricing and planning

Cost is a key factor when going with a firewall. Professional firewalls are expensive. However, personal firewalls are cheap; sometimes, you can get them for free.

Understandably, the cost directly affects the properties and functions of a firewall.

You are most likely to find a good personal firewall software with excellent functionalities for free more easily than a corporate firewall (the list we compiled below boasts all the best free ones we tested).

Security features

The best firewalls should be reliable and consistent and perform traffic analysis and filtering perfectly.

There should be no security holes in the firewall; it should alert if unauthorized access attempts come into play and should react automatically.


A firewall should have the vital features that people need to use.

Preferred features include the ability to control and detect threats, update threats based on cloud technologies, prevent intrusions, and integrate well with the environment.

Our Rating


Quality add-on modules

Doesn’t update regularly

Visit AVS Firewall

AVS Firewall differs from its counterpart as it has additional protection modules, including a registry, pop-up blocker, parental controls, and more. This firewall does not offer much customizable, but it offers many standard features and add-on modules.

The firewall offers three levels of protection:

  • Off, which makes the firewall disabled.
  • User: This protection level allows users to configure rules for connections).
  • High, blocking all connections.

Each function in the program interface is performed quite smoothly. Its alerts also provide clear and concise information. It supports Windows XP, 7, 8, and Vista.

AVS Firewall has four add-on modules, and each one of them is worth mentioning.

The first one is the registry protection module, which provides control and security of the registry for modifications (preventing malicious registry changes), with the ability to configure specific sections.

AVS Firewall

Next is the parental control module; as the name implies, it limits the available list of sites for kids, but you need to add each site manually.

Then comes the Module problem in logic, with which you can specifically allow certain websites alongside blocking individual sites.

Lastly, its pop-up blocker monitors browser behavior and blocks pop-up ads.

Notably, all four of these add-on modules can be individually disabled.

AVS Firewall also comes with a monitoring utility, which allows users to check the size of the passing network traffic for each application.

During the installation of this free firewall, the installer automatically installs the AVS secure browser.

Unfortunately, you cannot refuse the AVS browser’s automatic installation, but once the firewall is installed, you can remove it separately without any consequences for the firewall functionality.

In general, AVS Firewall is a pretty good firewall that will appeal to those who need additional security compared to basic firewalls and who do not want to dive deeper into the specifics of the network device.

You will be notified when a new application or service wants to go online, and you can allow or block it with one click.

GlassWire homepage

Notably, GlassWire is merely an interface built based on the Windows firewall, so it is not better than it, despite the attractiveness and improved information content.

9. PrivateFirewall (free)

Our Rating


Easy to configure

Not maintained since December 2013

Visit PrivateFirewall

PrivateFirewall is a PrivacyWare product. The functional product of the firm is a security system designed for business networks dubbed ThreatSentry.

The company no longer develops Private Firewall and does not mention the product on its website.

However, you can still download it (and for free) from software distribution platforms such as Softpedia. The program supports Windows from XP to 8.1 – there is no version for Windows 10.

This software is not only a firewall but also a host-level intrusion detection system. It checks the log files on your computer to find alarming events.

It will also protect these log files from unauthorized modification or deletion, a trick some malware programs use.

PrivateFirewall homepage

Typical firewall features that come in this program include whitelist and blacklist features, as well as content privacy controls such as text copying and clipboard monitoring.

The interface for the firewall is a pop-up context menu that you access by right-clicking on the program icon on the taskbar.

11. Windows Firewall (Free)

Our Rating


More likely to remain free for life

Interface isn’t user-friendly

Visit Windows Firewall

As the name suggests, Windows Firewall is part of Windows Defender. It is installed and activated by default and keeps on monitoring and blocking suspicious attacks.

It is very easy to configure and use; you only need to turn it from the Windows Defender. Like other firewall software, Windows Firewall boasts a blacklist and white list where you can configure the connections.

It is also worth considering which version of Microsoft Windows you are using.

For instance, the firewall in XP is not as effective as in Windows 7. Therefore, exploring a third-party firewall program may be better if you use an older Windows version.

You can use freeware such as (WFN) Windows Firewall Notifier and TinyWall to enhance the built-in Windows firewall functionality.

  • Block all the connection attempts that the user hasn’t allowed in the settings
  • It does not monitor, inspect, or proxy outbound communications

For Android

16. NoRoot Firewall (free)

NoRoot Firewall
Our Rating


Easy to use

Limited compatibility

Visit NoRoot Firewall

The majority of Android mobile applications require installation permission for establishing network connections.

Many of them genuinely need it for full-fledged functionality, while others use it only for targeted advertisements or other (not always useful) purposes.

By default, the Android OS does not contain security tools that would help regulate applications’ network activities. That is why it falls upon you to secure your Android.

And you can solve that problem using a third-party application called NoRoot Firewall.

NoRoot Firewall homepage

The work of this utility precisely matches its name and will not bring doubts to anyone’s mind who has encountered all the settings of any firewall in Windows.

NoRoot Firewall notifies when applications try to access the internet and enables you to permit or deny the appropriate connection.

Thus, you deploy a set of rules to which any program installed on your Android device will gain network access.

In addition to global rules, you can specify more subtle specific instructions for each program.

This means it is possible to specify a list of addresses to which access is allowed or denied and even a connection method for each connection.

Subsequently, the NoRoot Firewall saves connection logs, too, so you can see which app sent/received data and where.

Unlike many competitors, this free Android firewall program works by creating a secure VPN connection and does not require superuser rights.

Please note that NoRoot Firewall might not work on LTE since it does not support IPv6 currently.

  • No need to root your Android to make it work
  • Asks for minimal permissions
  • No phone number or location access is required
  • It doesn’t support IPv6.

17. AFWall + (free)

Our Rating


Allows importing DroidWall rules

Limted features

Visit AFWall

It is one of the most advanced firewalls for Android. AFWall allows you to fine-tune the built-in Linux utility iptables, adjusting selective or global blocking of access to the Internet as per your liking.

Key features of the program include highlighting the color of system applications in the list (to avoid problems, system components should not be prohibited from accessing the Internet), maintaining a detailed statistics log, and importing settings from other devices.

Besides, this firewall can be protected from unwanted access or deletion, and perhaps that is why it requires your Android device to be rooted.

Of course, the Android rooting requirement is a big disadvantage of AFWall, and for this reason alone, we would not recommend using it.

  • VPN and LAN support
  • Supports Tor
  • Root required

Are built-in firewalls not good enough?

A built-in firewall can merely take your internet security so far, which is why a purpose-built third-party firewall is needed.

It will add another layer of protection to your device and applications so that even if hackers find their way through the operating system, they are hit with an extra security shield they cannot break.

Think of it like the antivirus doing half the job and then a quality third-party firewall combining forces with it; you get protection 24/7.

Most of the free firewalls I have listed in this article offer much more than the bare bones of a built-in firewall system.

These are designed to prevent malicious attacks once they are inside your network. Preventing your network from communicating outside insecurely, causing any damage, and letting viruses or worms in, removing threats from your system without causing any harm to files.

Unfortunately, cyber-attacks are persistent in this age, and to stop viruses, malware, or other malicious things from damaging your device, you need protection that is designed for you specifically.

If all you need is firewall software that bars incoming connections, then the built-in firewalls that come with your operating system will work fine.

On the other side, if you want additional security layers and more advanced features, then it is recommended that you get your hands on a third-party firewall.

Third-party firewalls give you complete protection with advanced features, app or file change detection, providing timely information on network activities, spoofing monitoring, bandwidth consumption alerts for certain applications, and much more.

Of course, you can try using third-party tools alongside built-in firewalls for helping to extend their capabilities. But having two lines of defense together is never a good idea if you ask us.


Your computer or any other device should have layers of security measures, not just a single program protecting it.

In this age of never-ending cyber threats, computer firewalls should not be considered optional anymore.

Alongside picking a good free firewall from the list above, you should never ignore installing a quality antivirus on your device.

Also, consider using a premium VPN such as ExpressVPN (if you can afford a few bucks for your online privacy) to complete the puzzle of stealthy security while online.

The Internet contains risky websites, hackers, and malware designed to nestle on your device. Installing a reliable firewall and antivirus on your system is essential. And ideally, use a VPN.

Even if free firewalls and antivirus programs sometimes cause your computer to slow down slightly, they protect your machine and sensitive information from hackers and other criminals.
