Web Application Pentesting Tools

Web Application Pentesting Tools are the most essential part of the penetration testing process when it comes to web-based applications. 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 simply turns normal hackers or security experts into cyborgs, computer-enhanced humans and capable of testing much more than ever.

What is Penetration Testing?

The penetration testing is also known as ethical hacking as well, and it is basically, a practice to test a computer system, network or web application simply to find vulnerabilities that an attacker 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 be utilized to prove compliance with an organization’s security policy, the safety awareness of its staff and users; and the ability of the organization to identify and combat those security errors or attacks.

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

Some penetration testing tools are free 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, as well as the types of vulnerabilities they are looking for.

Generally, some of them offer an unlimited number of IP addresses or hosts to exploit, and others don’t. Some are specific to operating systems, and others are agnostic.

Basically, 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, efficient, and smarter.

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

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

Thus this security testing tool supports the command-line path for advanced users. 

Moreover, it has been the most notable OWASP project; it has awarded as the flagship status.

ZAP is written basically in Java, and it can further be used to prevent a proxy for manually testing a webpage.

ZAP is free to use, and it has a scanner and security vulnerability finder for web statements.


  • SQL injection
  • Private IP disclosure
  • Application error disclosure
  • Cookie, not HTTP only flag
  • XSS injection



W3af is one of the Web Application Attack and Audit Framework, which is developed by using Python.

This tool simply enables testers to find over 200 varieties of security problems in web applications.

W3af has a command-line interface and works on Linux, Apple Mac OS X, and Microsoft Windows. w3af is basically classified into two main parts, that are the core and plug-ins.

The core part regulates the process and contributes features that are applied by the plug-ins; hence, it gets vulnerabilities and utilizes them.

Moreover, the plug-ins are correlated and share information using a database.


  • Blind SQL injection
  • Cross-site scripting
  • Payloads injection
  • CSRF
  • Insecure DAV configuration

4. Arachni

Web Application Pentesting Tools

Arachni is created to recognize security issues inside a webpage, and it is basically an open-source security protection testing tool that is capable of uncovering several vulnerabilities.

Moreover, it helps in examining web application security, and it works as a meta-analysis on the HTTP acknowledgments it receives during an audit method and presents several insights and to know how to secure the application.


  • Local and remote file inclusion
  • SQL injection
  • XSS injection
  • Invalidated redirect


Web Application Pentesting Tools

Wapiti is one of the leading Web Application Pentesting Tools, and Wapiti is a free of cost open-source project from SourceForge.

If you want to check web applications for security vulnerabilities, Then it performs as black-box testing.

Hence, it is a command-line application, and most importantly, it knows multiple commands used by Wapiti. It is easy to use for the experienced, but testing for newcomers is a bit difficult.

But the new users don’t need to worry, as you can easily find all the Wapiti directions on the official documentation.

Hence, for checking if a script is vulnerable or not, Wapiti injects payloads, and the open-source security testing tool grants support for both GET and POST HTTP attack techniques.

6. Metasploit

Web Application Pentesting Tools

Metasploit is one of the most advanced and popular frameworks in the Web Application Pentesting Tools list that can be used for penetration testing.

It was based on the concept of ‘exploit,’ which is a code that can exceed the security rules and enter a reliable system.

Hence, if it entered, then it runs a ‘payload,’ a code that executes operations on a target machine, thus forming a perfect framework for penetration testing.

Moreover, it can be practiced on web apps, networks, servers, etc. As it has a command-line, and the GUI clickable interface that flawlessly works on all the major platforms like Linux, Apple Mac OS X, and Microsoft Windows though there might be some free limited trials available, as it’s a commercial product.

You can take the Mastering in Metasploit online course to enhance your skills in Metasploit.
