19 Powerful Penetration Testing Tools Used By Pros in 2021

List and Comparison of the Top Penetration Testing Tools (Security Testing Tools) used by the professionals. Research Done for you!

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 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.

Let us now quickly see:

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 a “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 could cause a security breach for the system.
Step #2. If possible, this list of items is ranked in order of priority/criticality
Step #3. Device 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 a 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.

The 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?

  • Even if you design a test on what to attack and how to leverage it, a lot of tools that are available in the market to hit the problem areas and collect data quickly that in turn would enable effective security analysis of the system.

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.

  1. Agree with this list, covers essential tools required for any pentester doing basic web and infrastructure testing. I also use AttackForge.com to manage pentesting projects and for automated reporting.

  2. Network Security Toolkit has an advanced Web User Interface for system/network administration, navigation, automation, network monitoring & analysis and configuration of many applications found in Network Security Toolkit distro.

  3. Netsparker is legendary. The ease of use and noob friendliness makes it way better than the rest. I must also add that its very powerful too and gives very accurate results.

  4. These are some of the go to tools for pentesting, we just started using another tool which helps manage pentesting and automate reporting although we don’t have to do that anymore as the platform also provides a login profile to our internal teams (our customers), they login see the projects and push findings to tickets.


    I see now they also have a sort of freemium version, also a lot of the tools above can be imported in to the tool itself.

  5. hi can anyone help me? Let say there is a website that have sql injection security, is there other issue related? Especially for login page or website with authorization?
