Overview

What is GSE?

The GIAC Security Expert (GSE) is the highest distinction in the GIAC certification system and was fundamentally reformed in 2023/2024: Instead of a single exam, it is now awarded as a portfolio certification. Those who demonstrate six Practitioner and four Applied Knowledge certifications (hands-on, proctored lab exams) automatically receive GSE status. The model enforces genuine breadth and depth – which increases credibility compared to earlier pure knowledge tests. However, the effort (cost, time, multiple exams) is considerable; the GSE is therefore clearly aimed at experienced experts pursuing SANS/GIAC as a career path. In Europe, awareness outside the SANS community is still limited.
