About OWASP ZAP

OWASP ZAP is a powerful, open-source web application security scanner designed to identify vulnerabilities during the development lifecycle. It functions as an intercepting proxy, enabling developers and security professionals to inspect and modify traffic between browsers and web applications. Its primary differentiator is its extensive automation capabilities and robust API, which allow for seamless integration into CI/CD pipelines. By providing both manual testing tools and automated scanning features, ZAP serves as an essential, cost-effective utility for teams prioritizing proactive security testing and vulnerability management.
