Port Authority

A handy systems and security-focused tool, Port Authority is a very fast port
scanner. It also allows you to quickly discover hosts on your network and will
display useful network information about your device and other hosts.

One of the fastest port scanners with host discovery on the market! Host
discovery is typically performed in less than 5 seconds. If the device you're
scanning drops packets, it takes about 10 seconds to scan 1000 ports. If the
device you're scanning rejects packets, it takes less than 30 seconds to scan
all 65,535 ports!
