GPEN – GIAC Penetration Tester

The GIAC Penetration Tester (GPEN) is a hands-on cybersecurity designation awarded by GIAC. It validates practical skills in network and web application penetration testing, ethical hacking, and vulnerability exploitation — making it a respected credential for red teamers, consultants, and technical leads in offensive security.
GPEN is closely aligned with SANS SEC560 training and emphasizes real-world attack simulation, post-exploitation techniques, and rules of engagement. It’s widely adopted by organizations seeking to assess and strengthen their defensive posture through authorized testing and adversarial emulation.
