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!

(1) ★★★★ DumpSec (#109, new!)

DumpSec is a security auditing program for Microsoft Windows NT/XP/200x. It dumps the permissions (DACLs) and audit settings (SACLs) for the file system, registry, printers and shares in a concise, readable format, so that holes in system security are readily apparent. DumpSec also dumps user, group and replication information. Read 2 reviews.

Latest release: version 2.8.6 on June 3, 2010 (14 years, 7 months ago).

(6) ★★★★½ SAINT Security Suite (#110, 19)

SAINT is a commercial vulnerability assessment and penetration system. It was originally developed in the late 1990's as free UNIX tool based on the open source SATAN scanner. Later it went commercial and broadened into a whole suite of tools for vulnerability detection, exploitation, and asset management. It is available on multiple platforms, including appliances (SAINTbox) and cloud-hosted (SAINTcloud). Top competitors include Nessus, Nexpose, and QualysGuard. Read 12 reviews.

Latest release: version 9.8 on May 1, 2020 (4 years, 8 months ago).

(3) ★★★★½ NBTScan (#111, 72)

NBTScan is a program for scanning IP networks for NetBIOS name information (similar to what the Windows nbtstat tool provides against single hosts). It sends a NetBIOS status query to each address in a supplied range and lists received information in human readable form. For each responded host it lists IP address, NetBIOS computer name, logged-in user name and MAC address. The original nbtscan was written by Alla Bezroutchko. Steve Friedl has written an alternate implementation. Read 4 reviews.

Latest release: version 1.5.1 on June 1, 2003 (21 years, 7 months ago).

(1) ★★★★★ DirBuster (#112, new!)

DirBuster searches for hidden pages and directories on a web server. Sometimes developers will leave a page accessible, but unlinked; DirBuster is meant to find these potential vulnerabilities. This is a Java application developed by OWASP. Read 2 reviews.

Latest release: version 2.0-RC1 on March 3, 2009 (15 years, 10 months ago).

(1) ★★★★ WinDbg (#113, new!)

WinDbg is a graphical debugger from Microsoft. It is actually just one component of the Debugging Tools for Windows package, which also includes the KD, CDB, and NTSD debuggers. Its claim to fame is debugging memory dumps produced after a crash. It can even debug in kernel mode. Read 1 review.

Latest release: version 10.0.10075.9 on April 29, 2015 (9 years, 8 months ago).

(2) ★½ ArcSight SIEM platform (#115, new!)

ArcSight provides a suite of tools for SIEM—security information and event management. The best-known seems to be ArcSight Enterprise Security Manager (ESM), described as the "brain" of the SIEM platform. It is a log analyzer and correlation engine designed to sift out important network events. The ESM itself is a standalone appliance, and the management programs run on Linux, Windows, AIX, and Solaris. For open-source alternatives see OSSEC HIDS and OSSIM. Read 2 reviews.

no rating SELinux (#118, new!)

Security Enhanced Linux (SELinux) is a security enhancement to Linux implementing mandatory access control (MAC). Users and processes can be granted their least required privileges in a much more granular way than with traditional Unix access control. For example, you can define a policy to prevent your web browser from reading your SSH keys. The security model of SELinux has been ported to other operating systems; see SEBSD for FreeBSD and Project fmac for OpenSolaris. Read 1 review.

(3) ★★★½ Brutus (#119, 42)

This Windows-only cracker bangs against network services of remote systems trying to guess passwords by using a dictionary and permutations thereof. It supports HTTP, POP3, FTP, SMB, TELNET, IMAP, NNTP, and more. No source code is available. UNIX users should take a look at THC Hydra. Read 3 reviews.

Latest release: version AET2 on Jan. 28, 2000 (24 years, 11 months ago).

(1) ★★ EnCase (#120, new!)

EnCase is a suite of computer forensics software, commonly used by law enforcement. Its wide use has made it a de-facto standard in forensics. It is made to collect data from a computer in a forensically sound manner (employing checksums to help detect tampering). Read 2 reviews.

Latest release: version 7.10.05 on March 18, 2015 (9 years, 9 months ago).

(1) ★★★★★ WebGoat (#122, new!)

WebGoat is a deliberately insecure J2EE web application maintained by OWASP designed to teach web application security lessons. In each lesson, users must demonstrate their understanding of a security issue by exploiting a real vulnerability in the WebGoat application. For example, in one of the lessons the user must use SQL injection to steal fake credit card numbers. The application is a realistic teaching environment, providing users with hints and code to further explain the lesson. Read 1 review.

Latest release: version 5.3 RC1 on Nov. 1, 2009 (15 years, 2 months ago).
