Port Authority

Port scanner

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!

Features:


  • Heavily threaded, no more waiting for results one at a time

  • LAN host discovery

  • Public IP discovery

  • MAC address vendor detection

  • LAN/WAN host TCP port scanning

  • Custom port range scans

  • Open discovered HTTP(S) services to browser

  • Lightweight service fingerprinting (SSH/HTTP(S) server type and version)

  • DNS record lookups supporting almost every record type

  • Wake-on-LAN for LAN hosts
