What is GIAC certification?

GIAC certification ensures that cybersecurity professionals meet and demonstrate specific levels of technical proficiency. You’ll get hands-on training in the latest cybersecurity skills across various roles, meaning you can put your certification expertise to work immediately.

Certification types

Becoming certified through GIAC means you have learned and mastered cybersecurity fundamentals. GIAC now offers stackable certifications that validate your cybersecurity abilities:

• Practitioner Certifications are designed for those new to certification and seeking to build foundational knowledge and credibility across a spectrum of infosec topics. GIAC currently offers over 40 Practitioner Certifications in areas such as offensive operations, cyber defense, cloud security, DFIR, management, and ICS. Practitioner Certifications are stackable, meaning you can use them to build toward GIAC's more advanced Applied Knowledge and Portfolio Certifications.

• Applied Knowledge Certifications offer a more challenging tier of subject matter and testing intended to validate certification holders' expertise. The hands-on exams showcase testers' technical knowledge and skills by solving complex real-world security scenarios.

• Portfolio Certifications allow security professionals to utilize stackability to customize their credentials around specific skill sets. GIAC Security Professionals (GSPs) is the first tier of portfolio certification (any three Practitioner certifications plus two Applied Knowledge certifications), followed by the highest certification level (any six Practitioner certifications plus four Applied Knowledge certifications), the GIAC Security Expert (GSE).

Is GIAC for beginners? 

GIAC offers different kinds of certifications to support you at the beginning of your career and as you advance and build your skills. GIAC Practitioner Certifications are appropriate for learners who want to demonstrate they have foundational knowledge of the topic. However, you should have experience or take a training course before attempting the certification exam. 

How long does GIAC training and certification take?

GIAC candidates preparing for the Practitioner exam spend an average of 55 hours or more studying and take an average of one practice exam before sitting for the official certification exam [2]. 

Certification renewal

• Retake the exam.

• Collect 36 continuing professional education (CPE) credits during the four years your certification is active [3].

Keep in mind: The renewal fee is $499 as of September 2025 [4].
