Did you ever ask yourself if your firewall is secure enough for your internet activities? The major concern nowadays is related to software programs installed on your computer which may contact and exchange information with the outside world without being authorized or noticed by you.

Odds are that your machine is wide open if you do not have a firewall installed on your system.If that is the case you may have already programs on your system that communicates with remote servers without you knowing about it. If you are unlucky, your system may be used in a bot net or someone is already stealing data from it.

AWFT probes the protection provided by your Personal Firewall software using six different tests. Each test uses a different technique for gaining access to the outside World.

Techniques are differently rated, according to their sophistication, and your Personal Firewall is doing a great job if is able to score 10 points in total.

If your Personal Firewall scored less than 10 points you may be able to adjust some settings to improve its performance. Do it and repeat the AWFT tests until you are happy. If you remain unhappy with your Personal Firewall you may, of course, try a different one.

Please note that you can only test five times before you will have to register the software. Download available at the Atelierweb homepage.

Update: Atelier Web Firewall Tester is no longer a free product. The download is no longer available. The latest version is available as a trial version only, the program retails for $19.95. the trial version is limited to ten runs before it cannot be used anymore unless purchased.

Here are a few alternatives that you may try instead. All of the following solutions are free.

  • CPL Test Suite - Run a couple of tests after you have downloaded the program to your PC.
  • Firewall Leakage Test - You download the program to your system and run it from there. It will perform a couple of leak tests.

Just download the programs or run the services directly from the web browser to start the firewall test.

    This is a worthless test, of course most firewalls will fail as they are designed to stop *incoming* traffic not *outgoing* traffic.

    To make matters worse the utility made me open Firefox just to run half of the tests. Of course it’s going to be able to get through the firewall as I requested the test have outbound access via port 80 do to the browser requirment.
