37 Most Powerful Penetration Testing Tools (Security Testing Tools)

A list of all the best and most popular Pen Testing/Security Testing tools required for every penetration tester is addressed in this article.

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

Penetration testing, commonly known as pen-testing is on a roll in the testing circle nowadays. The reason is not too hard to guess – with the change in the way computer systems are used and built, security takes the center stage.  Even though companies realize that 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 about Penetration Testing, you can check these guides:

Let us now quickly see:

What You Will Learn:

What is Penetration Testing?

It is a method of testing in which the areas of weakness in the 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 system.

Step #2. If possible, this list of items is 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) are done to determine if you can access data/network/server/website unauthorized.

Step #4. If unauthorized access is possible, then 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 perform Pen-testing.

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 the potential problems, whereas pen-testing is to attack those problems.

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

Before we look into the details of the tools, what they do, where you can 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

Here we go.

#1) Netsparker

Netsparker is a dead accurate automated scanner that will identify vulnerabilities such as SQL Injection and Cross-site Scripting in web applications and web APIs. Netsparker uniquely verifies the identified vulnerabilities proving they are real and not false positives.

Therefore you do not have to waste hours manually verifying the identified vulnerabilities once a scan is finished.

It is available as a Windows software and an online service.

#2) Acunetix

Acunetix is a fully automated web vulnerability scanner that detects and reports on over 4500 web application vulnerabilities including all variants of SQL Injection and XSS.

It complements the role of a penetration tester by automating tasks that can take hours to test for manually, delivering accurate results with no false positives at top speed.

Acunetix fully supports HTML5, JavaScript and Single-page applications as well as CMS systems. It includes advanced manual tools for penetration testers and integrates with popular Issue Trackers and WAFs.

#3) Metasploit

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 a perfect framework for penetration testing.

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

#4) Wireshark

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 the link below.

#8) Burpsuite

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 the 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.
