NmapNmapis one of the best network security scanners out there. Nmap will scan for all the computers and services that are currently running on the network. This application will not only scan for the available services on the network like most other port scanners do, Nmap will try to gather as much information as it can about the remote computers such as which operating system they are using, device type, firewall information, current uptime & the vendor of the network card in use.
