How to test your firewall's efficiency

Comodo is a Windows-based firewall that monitors and controls both inward and outward data flow through the system. It protects your system from viruses, trojans, worms, hackers, and other such threats. You can install it in a minute, it's that simple. The home screen looks pretty neat and has four components: Summary, Firewall, Defense+ & More. The “Summary” tab shows the current status of the system and the recent activities done by Comodo. The “Firewall” tab is for configuring the settings for defining and viewing different events handled by the firewall. “Defense+” lets you block the bad content that could prove harmful to your system, while the “More” tab lets you configure other miscellaneous firewall settings.

In the PcFlank Leak test, that tests the ability of the firewall to block unauthorised transmission of data, Comodo came out with flying colors. This becomes even more significant if you take into account that both Windows and Zonealarm failed this test. In the Advanced Port scanner test, first the true IP was identified and the status of ports in different modes (Stealthed, Open or Closed) were displayed. We concluded that the result was better for Comodo (80% in stealthed mode) as compared to the ZoneAlarm firewall (69% in stealthed mode).
