Introduction

In the past, many popular websites have been hacked. Hackers are active and always trying to hack websites and leak data. This is why security testing of web applications is very important. And this is where web application security scanners come into play. 

A web application security scanner is a software program which performs automatic black-box testing on a web application and identifies security vulnerabilities. Scanners do not access the source code; they only perform functional testing and try to find security vulnerabilities. Various paid and free web application vulnerability scanners are available.

And do not confuse free tools and open-source tools! There are various other tools available for free, but they do not provide source code to other developers. Open-source tools are those which offer source codes to developers so that developers can modify the tool or help in further development.

These are the best open-source web application penetration testing tools.
