Nmap is not considered a security measure. Nmap is a scanner.

Once you have a server in place, or a network in place, you can use Nmap to scan for open ports, operating system types, and things of this nature. Nmap is used for creating a "map" of your network.

A very precise definition of Nmap can be found at http://www.nmap.org and http://en.wikipedia.org/wiki/Nmap
