Best penetration testing tools 2021

What is Penetration Testing?

Whenever we hear penetration testing or ethical hacking, We think about illegal works or harmful things. But it’s not what it looks like. Not all hackers harm your data. Sometimes it becomes necessary to hack someone for legal actions or for any other reasons. And to do this kind of works sometimes we need penetration testing tools.

Penetration testing is a security practice where a digital protection master tries to discover and use or misuse(depends on what kind of work he/she is doing) weaknesses in a PC framework. The motivation behind this attack is to recognize any shaky areas in a framework’s safeguards which assailants could exploit. All these tools are very useful because they allow you to find the weakness of any unknown system. 

We can likewise say that Penetration testing tools are used as a piece of a pen-test to automatize some particular undertakings, to create testing efficiency, and to investigate issues that may be trying to discover utilizing manual examination techniques alone.

Why We need these Penetration Testing Tools?

Now after understanding about Penetration testing tools many of you are thinking that why we need these tools? Can’t we do hacking without using tools? 

Well, the simple answer is that you can do hacking without these tools but it will take too much time every time. You will get bored doing the same lengthy process every time. So, to make some basic scanning and some other basic things easy you need tools. 

Also, these tools are very helpful in different software companies. They use these tools for protecting their operating systems from hackers who are stealing their important data.

These penetration testing are mostly done by network specialists, testers, or by security specialists.

Also, these Penetration testing tools provide the IT team a distinct prospect on how to encourage their lines of protection.

To do these amazing penetration testing you also need to choose the right tools. Because there are many tools for pen-testing.

You will get many of these tools pre-installed in some high profiled operating systems. You can check out the article on Best Operating system for ethical hacking for your reference.

So, without wasting much time let’s get started and simply explore the whole list that we have mentioned below.
