Port Scan
Free Port Scan
Our popular free port scan has been moved to Audit My PC.com - Port Scan Options can be found here.
Our port scan will test your firewall’s ability to block intrusion attempts. This is an important part of any security audit and may reveal a destructive program masquerading as a benign application; such an application could give a hacker complete control of your system!
Some firewalls permanently block an IP address if it detects a port scan. You’ll want to temporarily disable this autoblock feature (not the firewall) or you’ll receive incorrect results. Here’s why: If we start to test your firewall for ports 1 to 1024 and your firewall blocks our IP address after port 5, then the remaining ports will appear closed to us when in fact they may actually be open.
Port Scanning
This online port scan could cause an interruption in service on the system being audited. If you are running on a private network, you may be connected through a router, proxy, or firewall and the firewall test may by conducted on that device instead of your computer; if you are unsure, do not perform the port scan.
