Alternatives to the GIAC Penetration Tester Certification (GPEN) for Aspiring and Working Pen Testers

Key differences

• It emphasizes Active Directory attack paths and privilege escalation within an OffSec-owned course and lab, whereas the GIAC credential follows SANS-style coverage from reconnaissance through reporting.
• The assessment is a practical exam with a written report, which suits learners who want the pressure of a full engagement.
• It is built around self-directed lab practice and gives up the structured instructor-led training that often accompanies GIAC preparation.

Key differences

• Assessment is a set of live challenges with evidence collection and audit judgment, while the GIAC credential is delivered through lab-based questions.
• It builds on the EC-Council ethical hacking curriculum, so it often follows that provider's knowledge-based exam rather than standing alone.
• Scope is broad ethical hacking across networks and applications, giving up some of the depth on reconnaissance-to-reporting workflow in GIAC's version.
