Which are the best penetration testing tools in 2021?
Penetration testing is the process of scanning systems, networks or applications with the intention of discovering vulnerabilities before hackers identify them.
It’s more of a simulated cyber attack where the penetration tester users the tools and techniques that are available to a hacker. With these penetration testing tools you can then attack a system from outside or inside, just the way a hacker would do it.
Once you discover the security holes or vulnerabilities, you proceed to fix them.

In this article, we are going to look at the top 11 penetration testings tools you should learn in 2021.
Even though there are many other penetration testing tools, these are the tools that are most common among pentesters.
Most penetration testing tools work from a list of known vulnerabilities and security holes and then try to penetrate the system’s defences.
As a penetration tester, you’ll realize that there’s no one tools fits all…
You’ll often need to rely on a collection to be able to perform your duties to your satisfaction.
Let’s get started.
Metasploit is an open source penetration testing tool written in Ruby that is hugely popular among penetration testers.
This vulnerability exploitation tool is basically a collection of pentesting tools and frameworks capable of performing various pentesting tasks.
Through the metasploit security framework, you’ll be able to gain critical information regarding security vulnerabilities in a target machine.
