37 Most Powerful Penetration Testing Tools (Security Testing Tools)

Here is the list of the most popular best Pen Testing/Security Testing tools for every penetration tester.

Wouldn’t it be fun if a company hired you to hack its website/ network/ Server? Well, Yeah!

Penetration testing, commonly called as pen-testing is on a roll in the testing circle these days. The reason is not hard to guess – with the change in the way computer systems are used and built, security takes the center stage. Even though companies realize they can’t make every system 100% secure, they are extremely interested to know exactly what kind of security issues they are dealing with. That’s where Pen-testing comes handy with its use of ethical hacking techniques.

For more details check these guides:
=> Penetration testing – the complete guide
=> Security testing of web & desktop applications

Let us now quickly see:

What is Penetration Testing?

It’s the method of testing where the areas of weakness in software systems in terms of security are put to test to determine, if ‘weak-point’ is indeed one, that can be broken into or not.

Performed for: Websites/Servers/Networks

How is it performed?

Step #1. It starts with a list of Vulnerabilities/potential problem areas that would cause a security breach for the systems.
Step #2. If possible, this list of items has to be ranked in the order of priority/criticality
Step #3. Devise penetration tests that would work (attack your system) from both within the network and outside (externally) to determine if you can access data/network/server/website unauthorized.
Step #4. If the unauthorized access is possible, the system has to be corrected and the series of steps need to be re-run until the problem area is fixed.

Who performs Pen-testing?
Testers/ Network specialists/ Security Consultants

Note: it is important to note that pen-testing is not the same as vulnerability testing. The intention of vulnerability testing is just to identify potential problems, whereas pen-testing is to attach those problems.

Good news is, you do not have to start the process by yourself – you have a number of tools already in the market.  Why tools, you ask?

  • Even though you design the test on what to attack and how you can leverage a lot of tools that are available in the market to hit the problem areas and collect data quickly that enables effective security analysis of the system.

Before we look into the details of the tools, what they do, where can you get them, etc. , I would like to point out that the tools you use for pen-testing can be classified into two kinds – In simple words, they are scanners and attackers. This is because; by definition, pen-testing is exploiting the weak spots. So there are some software/tools that will show you the weak spots, some that show and attack. Literally speaking, the ‘show-ers’ are not pen-testing tools but they are inevitable for its success.

Top 20 Penetration Testing Tools

1) Metasploit 

Metasploit pentesting tool

This is the most advanced and popular Framework that can be used to for pen-testing. It is based on the concept of ‘exploit’ which is a code that can surpass the security measures and enter a certain system. If entered, it runs a ‘payload’, a code that performs operations on a target machine, thus creating the perfect framework for penetration testing.

It can be used on web applications, networks, servers etc. It has a command-line and a GUI clickable interface works on Linux, Apple Mac OS X and Microsoft Windows. This is a commercial product, although there might be free limited trials available.

2) Wireshark

Wireshark logo

This is basically a network protocol analyzer –popular for providing the minutest details about your network protocols, packet information, decryption etc. It can be used on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many other systems. The information that is retrieved via this tool can be viewed through a GUI or the TTY-mode TShark utility.  You can get your own free version of the tool from here.

Download link: Wireshark download

3) w3af


W3afis a Web Application Attack and Audit Framework.

Some of the features are: fast HTTP requests, integration of web and proxy servers into the code, injecting payloads into various kinds of HTTP requests etc.

7) Burpsuite

Burpsuite logo

Burp suite is also essentially a scanner (with a limited “intruder” tool for attacks), although many security testing specialists swear that pen-testing without this tool is unimaginable. The tool is not free, but very cost effective. Take a look at it on below download page. It mainly works wonders with intercepting proxy, crawling content and functionality, web application scanning etc.  You can use this on Windows, Mac OS X and Linux environments.

Hi there.

I think Secunia was not a suitable selection for this title. Also some of mentioned tools are a part of special distros like Backtrack which includes Metasploit, BeEF, …etc.

Anyway, I appreciate this useful list.

Best of luck bros

#20 Alex

There are no reporting tools in the list. If the report you deliver to your clients is poor, then it will make your testing look poor. Dont forget about reporting it is the most important part since without a report your clients do not get anything.

#21 binod

Sir i feel so glad that the indians are doing a good job in pentesting including u…….i have also.have some dreams please in my some researches plzzz this is my humble request to u….

#22 zero

Use kali, bugtraq or backbox linux … windows is shit linux rocks It contains tons of tools for penetration testing live happy

I would like to know what is the best online penetration testing course, and advises have you got for beginners in pen testing.


#33 Randy

Interesting that this list shows Nessus, NMAP and even the 1990’s SATAN open source tool, but does not show SAINT. SAINT’s current product offers vulnerability scanning; content scanning; web application scanning; exploit tools; vulnerability-specific exploits; pentest scan policies; configuration auditing; and even new research on vulnerabilities in router firmware. I would highly recommend it for inclusion on this list.

#34 Steve Meredith

Another useful Pen testing tool worth checking out is Traffic IQ. It can be used in a live network and has access to a library of over 9000 exploits and Snort rules

#35 Hackerz

i use metasploit, wireshark, nmap, hydra and aircrack-ng…

all in windows 7 -> in my pendrives (portable)

i find it intresting to use it all in portable becouse you don’t need your computer to make penetration tester

just pedrives is enaugh…

#36 Ankur

What a fool you are….backtrack/kalilinux itself a linux operating system, its not a tool you fool…..kali linux is one of and famous linux distribution for penetration.

#41 Gary Adams

Very nice article but you have forgotten the very first and most important step. Get authorization to penetrate the target in writing to include the scope of your efforts.
Also while these tools are great, don’t forget that true pen testing should include that use of social methods. Phishing, physical access, dumpster driving …
