Web application penetration testing is a process of assessing the security of web applications. It involves identifying, analyzing and exploiting vulnerabilities in web applications to gain access to sensitive data.

To facilitate this process, there are many free web application penetration testing tools available for download. These tools can help you quickly identify and fix security flaws in your web applications.

They can also be used to simulate real-world attacks and assess the effectiveness of your security measures. With these tools, you can ensure that your web applications are secure from potential threats and attacks.


OWASP ZAP is a free and open-source Web Application Penetration testing tool that helps security experts and developers identify vulnerabilities in web applications to prevent cyber-attacks. It is typically used to discover various security flaws in a web project throughout the development and testing phases.

Zed Attack Proxy, thanks to its user-friendly interface, can be used by both novices and specialists. As a result, for expert users, this security testing programme supports the command-line path.

Furthermore, it is the most notable OWASP project. It has been certified as a flagship project. ZAP is developed in Java and can be used to prevent a proxy from manually testing a website. ZAP is free to use and includes a web statement scanner and security vulnerability finder.

Cyver Core is a pentest management platform that offers Pentest-as-a-Service through a client-facing cloud portal.

The tool automatically creates vulnerability reports from tool outputs using work process automation. These reports may then be used to automatically create pentest reports from templates.

To more effectively manage the work of pentest teams, you may also develop and customise workflows, vulnerability framework checklists, and assessment data.

You may create, manage, and distribute pentest projects for customers using Kanban-style boards or calendars. Projects are entirely automated, so client information automatically populates in pertinent reports.


  • Pentest report automation
  • Team management
  • Client Portal
  • Jira integration
