What is GIAC certification?

GIAC Certifications is a leading certification body specializing in information security. The cybersecurity think tank SANS Institute founded the organization in 1999, building its reputation for developing some of the most rigorous and well-recognized information security certification standards in the world. 

GIAC, formerly known as Global Information Assurance Certification, provides over 60 cybersecurity-related certifications for professionals [1]. Each certification covers a skill-specific domain or focus area, such as ethical hacking, cyber defense, and penetration testing.

Obtaining a SANS GIAC certification is a credible way to validate your cybersecurity knowledge and let employers know you’re trained in the latest information security thinking and techniques. 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, digital forensics and incident response (DFIR), management, and industrial control systems (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?
