Personal Firewall Recommendations
Knowledgeable people say that an un-protected machine that is connected to the Internet can and will probably be penetrated within 72 hours or less. Without proper protection chances are you will be targeted and penetrated – even if you have nothing secret or important to hide.
That is why you MUST install and properly configure a firewall on your computer (the one that is connected to the Internet), or on a dedicated computer that will act as a dedicated firewall.
I’ve used many free/low-cost firewalls on various operating systems and different network scenarios. I’ll try to create a full section out of this page it the future, full with reviews and pros/cons for each deal. For now I’ll give you a list of links you can go through.
Note: The next firewall products are not listed in any particular order. Some of these products are free for all, some are free for home users, and others offer a shareware or limited-capability version you can download. Remember that links and product versions might change without notice. If you see a broken link or want to recommend or make a comment on one of these firewalls – please contact me via the Feedback page.
Note: I do not intend to update this page to often. I simply don’t have the time for this right now. If any of you feel that other new products should receive credit, or that listed products deserve to be deleted due to lack of functionality or discovered bugs – please mail me with the details and I’ll gladly edit the page .
