Welcome to the PC Flank's Leaktests Information Page

On this page, you'll find introductory information about all existing leaktests, along with aggregate firewalls' pass stats against those tests. At the end of the page you will find an advanced leaktests information page explaining leaktests in detail and providing extensive breakdown of firewalls' performance when they are subjected to leaktests. Please note that only commercial firewalls participate in the testing, and some pre-Windows2000 tests have now been revoked. Firewalls are being tested at default configurations; higher level of security for participating firewalls might yield better results.
