The service discovery feature, also known as service scan, quickly detects active TCP services on a target host or network. Service discovery also gives its best with ethernet-based networks, where TCP SYN scan technique can be applied to audit active services on any host in a few seconds.
You can scan a local or remote host but also entire networks.

By default discovered services are reported on console as a plain text output, but you can choose between different output formats: like text, CSV, XML and HTML. So it is actually possible not only to use it as a command line administrative tool, but also integrated with your 3rd party applications.
