Despite Windows built-in firewall (Windows defender) a lot of us (including me) would rather have an additional, third-party firewall up. That’s where this list of best free firewalls comes to the rescue.
The firewalls listed here have been topping all the charts on the internet and offline for various reasons. Most just offer extreme protection, others are lightweight and offer an easy to use interface.
Although note that some of the firewalls listed here may be freemium. Meaning, you can purchase their premium versions for additional features.
15 Best Free Firewall for Windows
Here are Top 15 Free Firewall that you can use on your Windows 10, 8 or 7 PC.
- Comodo Firewall
- Outpost
- Glass Wire
- Tiny Wall
- Private Firewall
- AVS Firewall
- Avast free Antivirus.
- Zone Alarm
- Evorim
- PeerBlock.
- Net Defender
- Sofos XG
- OpenDNS
- Ashampoo
- R- Firewall
1. Comodo Firewall
My personal favorite feature that Comodo offers is its “Sandbox” mode. You can sandbox any program, which will run the program in an isolated mode so that any attack, breach of that program won’t seep into the rest of your OS.
Apart from that you can easily allow/block certain applications from accessing the Internet. The ease of adding programs to this list is commendable as well.
Tells you how trustworthy a program is from its “Rating scan” feature. The only problem however is that if you’re a victim of exploit attacks, Comodo is rendered useless.
Features a Browser-cleanup feature as well as game-mode for better performance of both.
Pros:
- Sandboxed Mode.
- Kill-switch
- Easy Blocking/Unblocking internet access.
- Rating Scan
- Automated Alerts.
Cons:
- Helpless against Exploit attacks.
- Auto-installs Search-engine unless disabled during installation.
2. OutPost
The best feature about OutPost is its in-built file and folder locker! Or you may fall in love with its multi-layered security protocols. You can actually customize each of the four security layers manually.
Also offers an in-built anti-leak module to prevent unwanted traffic from getting out. Has a connection monitor as well which helps identify unwanted outgoing connections.
Its program activity tracker would let you see which app modifies what on your system. The interface is extremely easy to use.
Pros:
- Easy to use.
- Lightweight
- File and folder locker.
- Four layers of security.
Cons:
- Number of popups is overwhelming.
3. GlassWire
An advanced, graphic-rich interface is what attracted me to Glasswire first. (Yeah I like shiny things!) It shows a list of programs and the exact hosts they’re connected to. If something seems fishy, feel free to close it.
It also stores “alert” information so you can always go back and check whatever made Glasswire suspicious. Then there’s a network monitor which monitors your WiFi and connection from other computers.
This free firewall allows multiple profiles for difference situations. Also can monitor, as well as adjust bandwidth usage/allocation for various apps.
Pros:
- Graphical UI
- Network Monitor
- Advanced lock down mode.
Cons:
- Not completely free.
4. Tiny Wall
A must-have especially for those who spend their days mostly on the Internet (who doesn’t?). Also for those who don’t like hopping through tens of windows before their firewall is configured. And hey, if you’re low on space it consumes less than 1Mb of your disk space!
Isn’t extremely feature-rich though. Does show instant, real-time alerts in a minimized, small window so whatever you’re doing isn’t interrupted. Lets you whitelist sites and apps which you think are safe. And offers basic WiFi protection.
That’s about it!
Pros:
- Easy and Fast to setup.
- Extremely lightweight.
- Basic protection.
Cons:
- Is super low on features.
5. Private Firewall
A forgotten, but not fallen hero is what Private Firewall is. The parent-company doesn’t work, update or probably even remember they birthed this baby once. Ironically, It still is one of the best free firewall software.
It allows whitelisting/blocking apps and websites. Clipboard monitoring, screen-content monitoring, E-mail monitoring are some additional features that it offers. Suspicious websites are auto-blocked.
E-mails are monitored as well. Offers advanced level host-scanning and monitoring.
Pros:
- Extremely feature-rich.
- Easy to use
- Port tracking available.
Cons:
- A lot of “text” on the interface.
- Isn’t available for Windows 10.
6. AVS Firewall
If you’ve got kids, you’d absolutely love AVS. Primarily for its Parental-control features which most other options on this list lack. You define the list of websites your kids visit, keeps them from maturing “too” fast.
You get to choose which websites and IP addresses are allowed to connect to your system, and which aren’t. Your registry is protected as well, alterations too are monitored. Also doubles as an ad-blocker. Set security levels, as well as control which apps connect or don’t connect to the internet.
Pros:
- Parental control.
- Registry monitoring.
- Security levels.
Cons:
- Installation process isn’t impressive.
7. Avast Free Antivirus
Avast is one of the most professional and established name in the industry. It offer a free version of its antivirus and firewall which you can use.
Some of the features include a sandbox mode for new, suspicious apps, WiFi protection. It also has a Do not disturb mode which earlier was the “Game mode”.
It also monitors app behavior, and sends suspicious files to avast for detailed analysis. Additionally features a smart-scan feature.
Pro:
- Sandbox mode.
- WiFi protection.
- DND mode.
- Multi-layered security.
Cons:
- No major cons.
8. Zone Alarm
Arguably the most feature-rich best free firewall in 2024 on this list. For starters its free online cloud backup (upto 5Gb) is impressive. It prevents accidental data loss, corruption or deletion!
Then it offers a Public as well as Wireless network protection layers. Not just a firewall but it also is an Antivirus. It has two modes, “Auto learn” and “Max Security”. They basically are like an automated, easier setup (auto-learn) or a more manual setup and control (max security).
“Stealth mode” acts as an additional curtain for hackers and intruders. For U.S customers, it also has a “recovery assistance” in case of a breach.
Obviously other common features such as application control, network monitoring etc. are available as well.
Pros:
- Online Backup.
- Multi-layer security.
- Advanced features.
Cons:
- False flags are common.
9. Evorim
Its “Monitoring mode” is my personal favorite. Once enabled, all applications need user consent before being able to access the internet. It also prevents browsers, websites and software from collecting or sharing telemetry.
Evorim also shows you a list of all the programs currently running on the system, and lets users set permissions for each one of them individually.
The firewall also monitors apps’ background activities and notifies if there’s any transmission or suspicious activity. It can also be used simultaneously with an Antivirus already running on the system. Access rules can be set both for alphabetic website addresses, as well as IP Addresses.
Pros:
- Monitoring mode.
- Zones (for granting identical permissions to multiple apps).
- Blocks botnets, viruses and background data.
Cons:
- No major cons.
10. Peer Block
More than a firewall, it’s a “blocking tool”, like the name suggests. It lets you upload list of IP addresses to ban. These can be for sites, ads, of certain countries or anything else you wish to block.
The interface is extremely basic, you simply upload the list of IPs to ban and it takes care of the rest. This helps users protect themselves from unwanted incoming, as well as outgoing traffic.
Pros:
- Extremely lightweight.
- Easy to use.
Cons:
- Doesn’t have any advanced protections.

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 can grow that much without some practical reasons. The firewall market has many reasons for its growth.
However, most people use this protection to safeguard their important data or sensitive information.
You must also understand that you are at high risk of having your information stolen if you do not have a quality firewall program installed.
It 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 (whether complex firewalls used by big corporations or simple personal computer firewalls) is to allow legitimate communication to flow and eliminate or reduce unwanted network communications.
There are two basic classes: client firewalls and firewall computers. These two 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.
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.
Features
It 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.
List of best free firewalls to use in 2024
1. Peerblock (open-source, free)
PeerBlock is the successor to PeerGuardian (which is only actively supported on Linux). It blocks incoming and outgoing internet connections of IP addresses that are blacklisted on the internet.

The program allows the user to enable and disable IP and HTTP trackers, as well as a log indicating the time, source of the IP address, destination, and protocol of the tracker. You can also customize the interface of the program, as well as its activities.

6. AVS Firewall (free)
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 customization, 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.
It 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.
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.

Monitors all the traffic
Cons

This is a good free firewall software option for users who want a flexible protection setting without sacrificing ease of use.

For example, the program boasts simplified alerts but is also efficiently functional, so you can quickly apply actions and easily configure rules.
Also, the Outpost Firewall records all answers in pop-up messages without creating additional rules.
It notifies you of all configured rules in the training mode and notifies you of all automatically applied rules.
The firewall also controls various app activities that could be threatening, including access to critical system objects (registry files), memory injections, and driver loading.
Outpost database also includes a lot of pre-configured rule templates, which means setting up internet access for applications will most often consist of a couple of mouse clicks.
The installer will ask if you wish the firewall to learn for a week (using the auto-learning mode and manual training “Rules Wizard”). In this mode, the Outpost firewall automatically sets its recommended rules for known secure applications.
Outpost Firewall Free is a good choice for those seeking a balance of functionality and interface.

This firewall allows you to view an extensive amount of information, which can initially be a little confusing.
You will be notified when a new application or service wants to go online, and you can allow or block it with one click.
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.
The premium version of GlassWire includes additional features, such as microphone and webcam monitoring, storing recordings for over a month, and monitoring several remote connections.
But for normal work and home use, the free version should do.
Pros
-
Extremely user-friendly and very simple to use
-
Incognito feature for preventing the firewall from logging all traffic
Cons
-
You must block apps individually; you cannot block them all at once
9. PrivateFirewall (free)
PrivateFirewall is a PrivacyWare product. The firm’s functional product is a security system designed for business networks, which is 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.
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.
Apart from providing you with basic firewall functionalities, the tool will also monitor email activity, disable downloads from infected or blocked websites, and block Internet activity from the specified addresses.
Pros
-
Allows blocking specific IP addresses
Cons
-
It must be handled cautiously; you need administrator privileges to save updates
10. OpenDNS Home (free)
OpenDNS is unlike any free firewall you can download from the internet; this replaces your router’s settings when it connects to the internet through OpenDNS servers.
That means each of the devices available on your network stays protected.
OpenDNS Home automatically blocks known threats and offers many options for filtering internet data to protect your home and children from all kinds of dirt.
Also, it helps to avoid phishing attacks. The program is free and offers clear installation instructions for literally every device.
Pros
-
Two versions of OpenDNS (Family and Home) are available for free
-
It is owned and backed by Cisco, the multinational technology conglomerate
Cons
-
All traffic gets routed via the OpenDNS network

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 monitors and blocks 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.
Pros
-
Block all the connection attempts that the user hasn’t allowed in the settings
Cons
-
It does not monitor, inspect, or proxy outbound communications
For Mac
12. LuLu (free)
LuLu is a free, open-source macOS firewall designed to block unknown outgoing connections unless explicitly authorized by the user.
LuLu’s goal is simple: block any unidentified outgoing connections unless the user permits it.
Although it was made to detect malware by flagging unofficial network connections, it can also block Operating System components or third-party apps from transmitting data to remote servers.
Pros
-
Boasts automated blocking capabilities
-
Notifies whenever any app tries connecting to a remote server
Cons
-
It only restricts the processes on a Mac device from connection attempts external to the device

16. NoRoot Firewall (free)
The majority of Android mobile applications require installation permission to establish 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.
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.
Pros
-
No need to root your Android to make it work
-
Asks for minimal permissions
-
No phone number or location access is required
Cons
-
It doesn’t support IPv6.

Allows importing DroidWall rules
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.
Pros

VPN and LAN support

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.
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.
Firewalls act as gatekeepers that regulate data flow between internal and external networks based on security rules, while antivirus tools detect malicious activity in a computer or network system based on malware signatures and behaviors. Microsoft already packs Windows with a firewall and even antivirus, but there are also alternative and completely free firewall programs you can install. Many of them have features and options that are easier to use and understand than the ones Microsoft offers. Many antivirus programs also include firewalls, but we’ll only discuss dedicated firewall software here.

5 free and open-source alternatives to paid anti-virus software
Here are some free and open-source alternatives to commercial antivirus software available for Windows, Mac, and Linux.

Windows Firewall
The built-in option
Let’s start with the native option as a baseline. Windows devices come with Windows Security, a built-in system that helps protect against malware, viruses, and other threats. Part of this is Windows Firewall, which filters incoming and outgoing network traffic to keep your device secure. It can block or allow traffic based on things like IP addresses, protocols, and port numbers.
You can customize Windows Firewall to control which apps and services are allowed to connect to the network, making sure only the ones you trust can communicate online. It’s turned on by default in all versions of Windows and also supports Internet Protocol Security (IPsec), which lets you require authentication from devices trying to connect to yours.
Windows Firewall is good enough for most users. It blocks outside attacks, and if you’re using a security suite, its firewall does everything the built-in one does. It also adds features like program control and exploit detection.

Windows Firewall Control
It complements Windows Firewall
Windows Firewall Control improves the functionality of the built-in Windows Firewall by providing a more intuitive interface and additional management features. It allows users to monitor and modify network rules in real time.
It runs in the system tray and makes it easy to control the native firewall without the hassle of navigating through settings. Windows Firewall Control offers four filtering modes that can be adjusted with a single click – High Filtering, Medium Filtering, Low Filtering, and No Filtering.
The tool offers a simplified view of all active connections and detailed logs, which means you get insights into the behavior of applications and services. It also provides the ability to temporarily allow or block specific traffic without altering the underlying system configuration permanently.
