Port Scan Information

Our online firewall testing tool allows anyone to perform a port scan against the IP address of the system they are browsing from. This can reveal whether a firewall is in place and if any services are open to the public Internet. Note that this scan will only probe a small number of common ports, for a complete Nmap port scan against any system you have permission to scan visit our partners at HackerTarget.com.
