All GIAC exams are web-based, can be taken at home, and will be proctored (invigilated) remotely by ProctorU.
Detailed information on remote proctoring with ProctorU can be found here. Full details, including a how-to-guide, will be provided to you before you book the exam.
The exam has 75 questions, all multiple choice, which must be answered within a 2 hour period. The questions will be more in-depth than those provided in the SANS Foundation course practice quizzes.
