Technology has reached a long way, but so does hacking. Almost like the digital world, hacking methods and tools have also evolved further sophisticated and also threatening. In this blog, we will discuss open source security testing tools, open-source penetration testing tools, top 10 security testing tools, web application security testing tools, and application security testing tools. 

It is better late than sorry! It’s crucial to maintain your website or web applications foolproof against vicious activities. What you require to perform is to utilize some security testing tools to recognize and assess the extent of security problems with your web application(s). The central function of security testing is to accomplish functional testing of a web application under compliance and discover as many security problems as possible that could potentially direct to hacking. Entirely of this is performed without the desire to access the source code.

There are various free, paid, and open-source tools available to test the vulnerabilities and drawbacks in your web applications. The best thing about open-source tools, besides subsisting free, is that you can customize them to conform to your particular requirements.
