Comodo Personal FirewallComodo Personal Firewall
License: Freeware
Description: Comodo’s business is SSL certificates, so it’s somewhat of a puzzle as to why they developed a software firewall and are giving it away for free, but give it they do (actually, it’s because they had a surplus of smart programmers, and decided that it would be a good way to get brand recognition). Amazingly, this firewall seems to be the best in the industry, scoring on the top of the latest leak tests. A warning: CPF doesn’t play well with some antivirus programs that do intensive HTTP scanning (Kaspersky, for instance).
License: Freeware (for personal use)
Description: ZoneAlarm is a handy free firewall that’s been around for some time. It’s very configurable and comes pretty highly rated.
Outpost Firewall FreeOutpost Firewall Free
License: Freeware (for personal use)
Description: Outpost Firewall Free is a deprecated version of Agnitum’s popular Outpost Firewall. It provides basic connection monitoring, privacy management, and packet filtering, but may also providing a nagging upgrade screen.

    Astaro Security Gateway is a full featured security suite. It’s free for personal use (require a dedicated PC). You can find it at

    Great info, thanks.
    Are any of these firewalls Vista compatible?

  4. Ben says:

    ZoneAlarm is. Comodo will be as of v3 (you can find betas on the web). Sygate probably isn’t, and Outpost’s free version likely isn’t, since it’s old.

    Kerio isn’t yet, either, but I might take them off the list, since I can’t actually find a free version on their website anymore.

    Thanks for the quick answer.
    The Kerio free one is now from Sunbelt I think.

    I might wait for the Comodo one.

    Astaro needs it’s own PC. but i think zone alarm works with vista

    Outpost is very good, but like the full version it is not suitable for novices, including many not-self-explanatory menus and preferences (though great for power users).

    Zonealarm performs well, but is just friggin’ huge. Way too much memory usage and interface clutter for typical transparent firewall use.

    Comodo is my personal favorite. Small, just what one needs, nothing one doesn’t, shuts up when it should, only bothers you when it must. I used Outpost for years, but tired of the power user tweaking and now just want a transparent utility. Comodo is it.
