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!

(2) ★★★★★ NoScript (#85, new!)

NoScript is an add-on for Firefox that blocks JavaScript, Java, Flash, and other plugin content (allowing you to selectively re-enable them for certain sites). It also offers cross-site scripting protection. This is mainly designed to keep web users safe, but security testers can also use the add-on to see what scripts a site is using. One caution is that the NoScript author Giorgio Maone has been caught inserting hidden code into NoScript which disabled users' ad-blocking software so that ads would still show up on the NoScript web site. He did post a lengthy apology. Read 3 reviews.
