SecTools.Org: Top 125 Network Security Tools

For more than a decade, the Nmap Project has been cataloguing the network security community's favorite tools. In 2011 this site became much more dynamic, offering ratings, reviews, searching, sorting, and a new tool suggestion form. This site allows open source and commercial tools on any platform, except those tools that we maintain (such as the Nmap Security Scanner, Ncat network connector, and Nping packet manipulator).

We're very impressed by the collective smarts of the security community and we highly recommend reading the whole list and investigating any tools you are unfamiliar with. Click any tool name for more details on that particular application, including the chance to read (and write) reviews. Many site elements are explained by tool tips if you hover your mouse over them. Enjoy!

(3) ★★½ Angry IP Scanner (#66, 15)

Angry IP Scanner is a small open source Java application which performs host discovery ("ping scan") and port scans. The old 2.x release was Windows-only, but the new 3.X series runs on Linux, Mac, or Windows as long as Java is installed. Version 3.X omits the vampire zebra logo. As with all connect()-based scanners, performance on Windows XP SP2 and newer be poor due to limitations added to tcpip.sys. The FAQ provides details and workarounds. A short review was posted to nmap-dev in 2008. Read 4 reviews.

Latest release: version 3.0-beta4 on March 23, 2009 (14 years ago).

Superscan is a free Windows-only closed-source TCP/UDP port scanner by Foundstone (now part of McAfee). It includes a variety of additional networking tools such as ping, traceroute, HTTP HEAD, and whois. Some functionality has been crippled by restrictions imposed by Microsoft in Windows XP SP2 and newer releases. This tool is not really maintained (the latest release was in 2004). Read 4 reviews.

no rating Unicornscan (#116, 38)

Unicornscan is an attempt at a User-land Distributed TCP/IP stack for information gathering and correlation. It is intended to provide a researcher a superior interface for introducing a stimulus into and measuring a response from a TCP/IP enabled device or network. Some of its features include asynchronous stateless TCP scanning with all variations of TCP flags, asynchronous stateless TCP banner grabbing, and active/passive remote OS, application, and component identification by analyzing responses. Like Scanrand, it isn't for the faint of heart. Read 2 reviews.
