Top 5 Free Firewall software for Windows 8 | 7

The importance of a firewall cannot be over-emphasized. A Firewall can block threats that your antivirus may miss. Not only that, it can prevent hackers from breaking into your computer! The in-built Windows firewall is great – and just good enough for the regular home-user who wants protection and who does not want to be bothered with setting it up. Leaving the default values for your Windows firewall should suffice, and along with a good antivirus software, give you ample protection for your Windows computer. But if you want an easy UI that will help you configure the Windows Firewall, you could check out Windows 7 Firewall Control,  Windows Firewall Control and Windows Firewall Notifier.

Free Firewall software for Windows

However, if you are looking for a third-party firewall for your computer, there are several free solutions available. Let us check out some free stand-alone firewall software for your Windows PC.

Comodo Free Firewall

These days, the feature-rich and easy-to-use Comodo Free Firewall has become very popular. It promises to stealth your computer’s ports against hackers and will also block malicious software from transmitting your confidential data over the Internet. The Comodo Free Firewall will monitor all aspects of communications between your computer and the Internet. This prevents common hacking methods such as port scanning. The firewall references a list of over two million known PC-friendly applications. If a file is not on this ‘safe-list’, the Firewall immediately alerts you to the possibility of attacking malware.

ZoneAlarm Free Firewall

ZoneAlarm Free Firewall at one point of time was the most popular third-part firewall for Windows – but over a time some started getting the feeling that it had become too bloated. It is nevertheless still the worlds most downloaded firewall software.  The firewall is very easy to configure and fr an average user, its settings are best left at default. It is very effective in stopping Internet attacks at the front door and even catches thieves on their way out. Its 2-way firewall proactively protects against inbound and outbound attacks while making you invisible to hackers. There are still many today who swear by it.

Emsisoft Online Armor Free Firewall

Online Armor Free Firewall helps stop Hackers, stops Malicious Programs and protects your Identity. It offers the following protection: Kernel Mode Security, Web Shield File/Registry Shield, Phishing Filter, Execution Protection, Termination Protection Limited Autostart Protection, Keylogger Detection, Tamper Protection, DNS Spoofing Protection and Script/Worm protection. The free version offers lesser features as compared to its paid premium offering – but if its basic inbound-outbound protection you are looking for, this firewall servers the purpose.


There are ways you can configure the Windows firewall using some thirdy-party tool. TinyWall is freeware that further hardens the advanced firewall of Windows 7. It is a light-weight solution with negligibale performance impact and lets you work without giving out any pop-ups whatsoever. No additional drivers or kernal components are installed with it. TinyWall will give your Windows Firewall a secure configuration and present you with a simple interface where you can easily define what has network access and what not. It will also allow you to easily prevent other programs from modifing or overwriting your firewall settings.  If you are looking for a very basic and simple solution, you might want to consider using this firewall.


PrivateFirewall is a proactive, multi-layered defense solution for Windows desktops and servers. It detects, blocks and quarantines activity characteristic of known malware, hacking, phishing and other threat types. Its  packet inspection, URL filtering, anti-logger, process monitor, and application/system behavior modeling and anomaly detection components stop hackers, spyware, viruses and other forms of malware before they can cause damage. It is a 3.5MB download. (Updated thanks to Samit).

    Personally i use Online Armor Free and i think Comodo firewall and Online Armor are the two best out there…..both of them have strong HIPS…..

    Ashampoo firewall is discontinued product, it doesn’t support windows 7 at all and you forgot two great free firewalls…..Privatefirewall and Outpost free firewall…..although you can’t get separate setup file for outpost firewall free….you need to install outpost security suite and disable Antimalware component during install….

  • Anand Khanse

    Thanks for the inputs Samit. Replaced Ashampoo with PrivateFirewall, which I was not aware of.

    I have included only the standalone firewalls, hence did not include Outpost here. But yes – Outpost Security Suite does have a great firewall. You can read more about it here:

    Comodo firewall is the bomb, very light on the system not a resource hog and runs great with Eset Av. Defo the best.

    I found this thread REALLY late, but I’d like to mention re Privatefirewall. My Windows 7 Home Premium SP1 64 bit has issues with a Comodo FW kernel access driver (random BSODs); earlier in 2013, I checked 10/2012 Matousec report on FWs, found Comodo #1 and Privatefirewall #2; tried and have kept using Privatefirewall without OS/AV issues…but at each startup/restart, Privatefirewall (on its own untouchably set autorun) would cause a long blackish-screen hang between “Starting Windows” and LogIn screen, then take some time to load itself after logon. Recently I used Performance troubleshooter to not have Privatefirewall run startup; no change to hangs. So I went to “Start” menu, right-clicked “All Programs” to open startup folder, copied Privatewall icon into same so as to at least not forget to use it, and now every time my OS starts/restarts with no such hangs and Privatefirewall working as it should…a pleasant surprise for once.

    There are a very few types of malware Privatewall doesn’t protect against, but most competent AVs do; also, one needs a good antilogger (such as Zemana) as this FW doesn’t faze loggers. For those interested, my Privatefirewall on highest settings itself alone scores 290/330 current Comodo Leak Test…almost twice what my resident Windows firewall scored. Hope this is of use to at least some windows users.
