OWASP (the Open Worldwide Application Security Project) is a nonprofit foundation that aims to enhance software security. It offers several free open-source application security tools under its umbrella, with ZAP (Zed Attack Proxy) being one of the most popular. OWASP ZAP is a web application security scanner that is open-source, free to use and user-friendly. Developers can use ZAP to detect a wide range of vulnerabilities via automated and manual scanning.

Features of OWASP ZAP

Some of OWASP ZAP’s top features include:

  • Automated scans.
  • Passive scans.
  • Active scans.
  • Fuzz testing.
  • Intercept proxy.
  • Detailed reports.
  • Integrations.

ZAP’s automated web application scans can search for common security vulnerabilities to help developers spot and fix issues early in development. Its passive scans work well for catching issues automated scans may miss, and its active scans simulate real-world attacks to assess application resiliency.

OWASP ZAP’s fuzz testing or fuzzing sends unexpected data to the app to spot potential vulnerabilities, while its intercept proxy feature spots vulnerabilities that are invisible to the end user. The programmer tool also offers detailed reporting that offers insights for quick issue fixes, plus third-party integrations with automated testing workflows, CI/CD pipelines and other widely used tools.

OWASP ZAP has become a popular developer tool for security due to the following advantages it provides:

  • Free to use.
  • Active following.
  • Third-party integrations.
  • Custom scripts.

OWASP ZAP’s biggest advantage for many is its open-source nature, which makes it free to download and use. The programmer tool’s large community gives users added support, resources, extensions, etc. Third-party integrations with automated testing workflows and CI/CD pipelines make ZAP a perfect fit for DevSecOps teams. Developers who place a premium on customization will enjoy the ability to create custom testing scripts.


While it offers many advantages, OWASP ZAP has some disadvantages too, such as:

  • Possible added work.
  • Gaps in coverage.
  • High resource usage.
  • Excessive output.

One of the biggest reasons developers choose automated security testing tools is to save time and minimize work. Unfortunately, OWASP ZAP tends to produce false positives, which increases the workload of development and security teams since they must verify the existence of vulnerabilities manually. Another ZAP disadvantage is the need for additional coverage. Its DAST capabilities can spot a wide range of security issues, but not all, and should be paired with SAST or manual penetration testing for more complete coverage. Lastly, OWASP ZAP may have high resource consumption that negatively impacts app performance.

Pricing of OWASP ZAP

OWASP ZAP is an open-source security testing tool, which makes it free to download and use. This is one reason why OWASP ZAP is a popular security tool for developers, especially those with limited budgets.
