Web Application Pentesting Tools

Introduction :

Web Application Pentesting Tools are essential to the penetration testing process for web-based applications.

In this article, we list some of the free Web Application Pentesting Tools.

We all know very well that in the old days, hacking was quite difficult and required a lot of manual bit manipulation.

However, today, on the internet, we can find a complete set of automated test tools that turns normal hackers or security experts into cyborgs, computer-enhanced humans capable of testing much more than ever.

What is Penetration Testing?

Penetration testing is also known as ethical hacking.

Testing a computer system, network, or web application is a practice to find vulnerabilities that attackers or malicious hackers could exploit.

Penetration tests can be automated with software applications, or they can be performed manually.

The main objective of penetration tests is to determine security weaknesses. 

Apart from these things, penetration tests can also prove compliance with an organization’s security policy, the safety awareness of its staff and users, and the organization’s ability to identify and combat those security errors or attacks.

Hence, to reinforce the defenses, security professionals need to build a set of tools, both free and commercial.

Some free Web Application Pentesting Tools are available, and others are not, but they all serve a purpose: the administrator must find the vulnerabilities before hackers do.

Each tool differs in its scanning methods, which security administrators can implement, and the vulnerabilities they are looking for.

Generally, some offer an unlimited number of IP addresses or hosts to exploit, while others don’t.

Some are specific to operating systems, and others are agnostic.

We are in a stage where we should work smartly.

In short, why use a horse and carriage to cross the country when you can fly in a plane?

Hence, here we have created a list of smart penetration testing tools that make the work of a modern pentester faster, better, more efficient, and smarter.

Moreover, penetration tests are sometimes called “white hat attacks,” We all know that in these types of tests, good hackers or white hat hackers try to get into the force.

So, now without wasting much time, let’s explore the list below.
