OWASP ZAP (Zed Attack Proxy) is an open-source web application security scanner designed to help find vulnerabilities in web applications. It is widely used by developers and security professionals to identify security issues during the development process. ZAP provides automated scanners as well as various tools for manual testing, making it versatile for different user needs. ZAP supports a range of features, including passive and active scanning, fuzzing, and reporting. It can be integrated into continuous integration/continuous deployment (CI/CD) pipelines, enhancing security in software development. As part of the OWASP (Open Web Application Security Project) community, ZAP is continually updated to address emerging security threats.
