Leak Test - see how
well your firewall protects youGuest Review from JeanInMontana:
I can vouch for this tiny stand alone
program. It will tell you if you have any weak spots.
Quote from the website - Especially with "always-on" connections
such as digital subscriber line and cable, you can't assume that your
firewall keeps your data protected. This program simulates the presence
and effect of Trojan horses, viruses, and adware/spyware and lets you know
whether it was able to slip past your firewall's outbound protections and
establish a standard TCP connection with one of the manufacturer's
servers. (No personal data is sent, and no record is retained of your use
of the program.) If it can establish a connection--which it
shouldn't--you'll know that you need better protection against Internet
threats.
