Port Scan
This server will now attempt to open several common ports on your computer. The results of these attempts will be displayed on this page as Open, Closed, or Secure:

  • If your firewall is configured to block a port, and it is operating correctly, you will see Secure and an event will be logged on your firewall.
  • A Closed port indicates that the port is reachable but there is no program currently accepting connections there.
  • If the port is indicated as Open there is an application or service on your computer actively accepting connections.

The time to check each port will range from less than a second up to 20 seconds. Ports which are Secure will take the most time.
