OWASP ZAP

OWASP ZAP, or the Zed Attack Proxy, is a powerful open-source tool developed by the Open Web Application Security Project (OWASP) to help identify security vulnerabilities in web applications. It acts as a “man-in-the-middle” proxy, intercepting and modifying requests and responses between the user’s browser and the web server, allowing security professionals to test for vulnerabilities like cross-site scripting (XSS), SQL injection, and other common threats. With an intuitive GUI and robust automation capabilities, OWASP ZAP is popular among both beginners and advanced users for dynamic application security testing (DAST), making it essential in web application security assessments.
