Web application security testing — automated vulnerability scanning for XSS, SQL injection, and OWASP Top 10.
OWASP ZAP is my web application security testing tool. I run automated scans against staging environments to detect XSS, SQL injection, CSRF, and other OWASP Top 10 vulnerabilities. Integrated into CI/CD for automated security regression testing. I use both passive scanning during development and active scanning before releases.
