Top 9 Open Source Security Testing Tools for Web Applications

The Internet has expanded, but hacker practices have grown as well. Any news of a website being hacked or a data leak is available every now and then. Technology has gone a long way, but hacking has, too. Hacking methods and instruments have now grown more complex and also dangerous, much like the modern world.

Late, better than sorry! Holding the website or web applications foolproof against malicious attacks is critical. What you need to do is use certain vulnerability monitoring software to define and calculate the magnitude of your web application security problems (s).

The primary role of security testing is to conduct a web application’s functional testing under observance to detect as many security problems as possible that may possibly lead to hacking. Without the need to view the source code, all of this is finished.

Let’s first familiarize ourselves with the meaning, purpose, and need for security testing before delving into some of the best open-source security testing resources to test your web application.


The Definition-We use security checking to ensure that data inside any information system remains secure and not accessible by unapproved users. Effective protection monitoring defends web apps against extreme ransomware and other disruptive attacks that may cause them to crash or produce unpredictable conduct.

Security checking assists in the initial process to find out multiple vulnerabilities and weaknesses of a web application. In addition, it also assists in checking whether or not a program has successfully encrypted encryption code. The key fields that are covered by safety testing are:

  • Authentication Of
  • Authorizations
  • Disposability
  • Trustworthiness
  • Completeness
  • Non-repudiations

Organizations and experts all over the world use the Intent-Security test to ensure that their web apps and information systems remain secure. The key goals of security monitoring deployments are:

To further increase a product’s security and shelf-life
Identifying and addressing numerous security challenges at the early stage of production
To rate the level of stability in the current state

The Need-Why do we need testing for security? Ok, there are a variety of explanations, from analyzing the degree of protection in the future to avoiding accidental breakdowns. Any of the explanations that are most relevant are:

  • Avert incoherent production
  • Stop losing consumer interest
  • Avoid losing substantial data in the form of security leaks
  • Preventing theft of information by unidentified users
  • Save from unforeseen loss
  • Save the extra costs needed to repair safety problems

To check the weaknesses and bugs in your web apps, many free, paid, and open-source resources are available. Besides being unrestricted, the great thing about open-source software is that you can tailor them to meet your personal specifications.

So, here is the list of 11 testing tools for open source security to check how secure your website or web application is:

Top 10 Open Source Security Testing Tools

3. Wapiti

Wapiti is a free-of-charge, open source project from SourceForge and develops, one of the leading web application security testing tools. Wapiti conducts black box testing in order to audit web applications for security flaws. Since it is a command-line program, it is important to have an understanding of the different commands that Wapiti uses. For the experienced, but experimenting for beginners, Wapiti is quick to use. But don’t worry, you will find the official documents with all the Wapiti directions. Wapiti injects payloads to validate whether a script is insecure or not. Support for both GET and POST HTTP attack methods is offered by the open-source security testing tool. Wapiti disclosed flaws are:

  • Detection of Order Execution
  • Injection of CRLF
  • Injection of Servers
  • Disclosure of File
  • Shellshock or bug from Bash
  • SSRF-SSRF (Server Side Request Forgery)
  • Poor setups with .htaccess that can be bypassed
  • Injection of XSS
  • Injection of XXE

Principal highlights:

  • Enables authentication by various methods, such as Kerberos and NTLM,
  • Comes with a buster module on the targeted web server, supporting brute force directories and file names
  • Fits like a Fuzzer
  • Supporting both GET and POST HTTP attack methods

4. W3af

One of the most common security testing platforms for web applications that are also built using Python is W3af. The method helps testers to recognize more than 200 kinds of security problems in web apps, including:

  • Injection for Blind SQL
  • Overflow in buffers
  • Scripting Cross-Site
  • CSRF’s
  • DAV settings that are unstable

Principal highlights:

  • Help for Authentication
  • Simple to start with
  • Provides an insightful GUI interface
  • You should record the output into a monitor, file or email.
