free firewall programsAs noted in What Is The Definition Of A Firewall? [Technology Explained] What Is The Definition Of A Firewall? [Technology Explained] What Is The Definition Of A Firewall? [Technology Explained] Read More , a firewall is a piece of software that scans incoming and outgoing traffic for tell-tale signs of malevolent actions. It protects the resources of a private network from users outside the network, as well as preventing unauthorized programs from accessing the Internet.

There are many tools out there to help you manage your firewall’s operations, but there aren’t too many free ones. Putting a list together may help you contrast and compare the decent programs that are out there.


In this article, I am going to cover the top free firewall operations management tools, detailing their key features and where to find them.

1-3. Comodo Internet Security, PC Tools Firewall Plus Free Edition, ZoneAlarm Free Firewall

Last month, Matt wrote about The Three Best Free Firewalls for Windows The Three Best Free Firewalls for Windows The Three Best Free Firewalls for Windows Read More . The three firewall programs he wrote about are definitely worth revisiting and are a good starting point for this list. Since they were covered previously, I will only briefly cover them here.

Comodo, always a popular choice among our readers (see ’08 poll What Firewall Software do you Use ? [Poll] What Firewall Software do you Use ? [Poll] Read More ), has merged its antivirus program with Firewall Pro, creating a free security program for everyone. If you are only interested in the firewall (or antivirus), the installer does let you opt out of either of the components.

    Enables fine control of the Windows firewall and doesn't experience the drawbacks of the other firewall products.

    The built-in firewall has one critical issue I think that disqualifies it, and that is the ability to control it properly and easily. Windows 7 Firewall Control is something I find really makes up for that - it adds things like pop-ups when new apps want to access the net and allows for really easy per-app settings. The free version gives those benefits as well, the pay version gives more choices though. It still utilizes the perfectly functional built-in firewall in Vista and Win 7 - it just gives you a far less painful way of configuring it. For me that's plenty good enough which saves me from having to install any new firewall app when I already have a good one.

    The article was meant to be a list of alternatives to Windows built-in
    firewall, although Windows 7 does have a pretty good one. Thanks for
    pointing that out!

    You forgot Windows 7 firewall. It's very powerful if you know how to use it.

    ZoneAlarm is by far the worst firewall.
    I cannot trust anything created bt Comodo.
    Ashampoo FireWall looks good, but this is all good about it. It's development has long ago stopped. It cannot pass the simplest leakage tests.
    Online Armor is extremely intrusive and severely slows down Windows.
    I have never tested Filseclab.
    PC Tools Firewall Plus is good, but I prefer Outpost.
