Web application security is a central component of any web-based business. The global nature of the Internet exposes web properties to attack from different locations and various levels of scale and complexity. Web application security deals specifically with the security surrounding websites, web applications, and web services such as APIs. Below are some closed source tools that can be used for web application security:


Burpsuite Pro:

BurpSuite is a powerful web application security testing tool. It identifies the attack surface of a web application and then uses these vulnerabilities to perform further attacks. This tool was developed by Portswigger. This tool acts as a man in the middle for all the requests to and from the target web application.

Nessus Pro:

Nessus is a network vulnerability scanner that uses the Common Vulnerabilities and Exposures architecture for easy cross-linking between compliant security tools. Nessus has a modular architecture consisting of centralized servers that conduct scanning and remote clients that allow for administrator interaction.


Netsparker can understand and scan any language, including Node.JS, Python, Ruby, PHP, .NET, and others. Netsparker’s online scanner works by scanning web applications for common security vulnerabilities like Cross-site Scripting (XSS), SQL injection, and others like those listed in the OWASP top risks. Netsparker’s exclusive Proof-Based Scanning™ sets it apart from the competition.


Acunetix is a web application security tool that automatically performs a vulnerability assessment of a website or web application together with any server misconfigurations. Acunetix allows you to run security checks for thousands of vulnerabilities quickly and accurately on a regular basis.
