Frequently Asked Questions

What is the GIAC Certified Web Application Defender (GWEB) certification?

GWEB validates knowledge of securing web applications against the most critical threats. It covers access control, authentication, CSRF defences, input validation, encryption, session security, AJAX security, and web service hardening.

What are the GWEB exam requirements?

The GWEB exam consists of 75 questions, is web-based and proctored, has a 3-hour time limit, and requires a minimum passing score of 68%. Proctoring is available via ProctorU (remote) or PearsonVUE (onsite).

What topics does GWEB cover?

GWEB covers access control models, authentication and MFA, CSRF defences, input validation and output encoding, AJAX and web service security, encryption and TLS, session management, and security testing techniques aligned with OWASP ASVS.

Who should take GWEB?

GWEB is ideal for web developers building secure applications, application security engineers, code reviewers, QA and test engineers, DevSecOps professionals, and security architects designing web application security controls.

How does GWEB differ from GWAPT?

GWAPT is an offensive certification for penetration testers who identify and exploit web vulnerabilities. GWEB is a defensive certification focused on preventing those same vulnerabilities through secure design and implementation. Both are valuable and complementary.

Does GWEB cover modern web security topics?

Yes — GWEB covers modern security topics including API security, CORS policies, JSON security, SameSite cookies, Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and secure development lifecycle integration.
