Some people have been working on extensions to nmap which
add new features or benefit it with other improvements. Here are
the projects I am aware of (mail me if you have others):
Nmap Online is a handy web-based interface to Nmap--a way to scan yourself and see what your computer or network looks like from the Internet side. They also have an Nping Online system.
Self Audit My Server (SAMS) is a web-based application allowing you to run Nmap and a few other security tools against an Internet host.
Nmap-CGI is a web-based application for scanning your network with Nmap. It offers user management and privilege levels to control who can scan what.
is a Ruby library for executing Nmap scans and parsing the output for
use in a higher level application/script. It was created by Kris
Nmap scans programatically using Perl. It was written by Max Schubert (nmap&at&webwizarddesign.com).
Nmap-Parser is a Perl
module for parsing Nmap's XML output. It was created by Anthony Persaud.
Cancerbero is an nmap-based port scan engine which automates regular scans, storing results in MySQL and generating alerts, change reports, etc. A web interface is provided for configuration and data mining.
Inprotect offers free
(GPL) web frontend software for Nmap and Nessus, as well as certain services.
Joshua D. Abraham <jabra&at&ccs.neu.edu> has created Pbnj, a tool for running Nmap scans and diff'ing the results.
Remote nmap (Rnmap) is
a pair of client and server programs which allow for various
authorised clients to run their port scans from a centralised
server. It was written by Tuomo Makinen <tmakinen&at&pp.htv.fi>.
Alek O. Komarnitsky (alek&at&komar.org) has created nmap-web, a simple Perl/CGI
script(s) you install on your web server which allows you to submit nmap
commands (and receive the responses) through a web interface. This is
especially oriented toward "white-hat" Sysadmins trying to figure out what
ports are open and what versions of programs are running.
RadialNet is a gorgeous tool for visualizing Nmap data. It was created by João Paulo de Souza Medeiros. Note that this functionality is now included with our Zenmap GUI.
has created Winfingerprint, an
application that uses SMB to determine OS, shares, users, and other
information about Windows machines on a network (Note: this
scanner currently only runs on Windows).
