Nmap
Nmap, or 'Network Mapper' is a free and open-source security scanner, port scanner, and network exploration tool. It's also used by systems and network admins for tasks like monitoring host or service uptime, managing service upgrade schedules, and network inventory. Nmap leverages raw IP packets to learn more about hosts available on the network, the application name and version they offer, and operating system they're running.
Nmap is useful for discovering networks, learning what's running on them, and as an inventory solution, says Weiner, but businesses will need more technical know-how to fully use it. The tool was designed for larger networks and runs on all major operating systems.
'It's not without some work,' he notes. 'You have to take output from that and put it somewhere so you can understand its result in a cohesive way.'
