FAQs

Frequently Asked Questions

What is the GIAC Defending Advanced Threats (GDAT) certification?

GDAT validates a practitioner's ability to detect, prevent, and respond to the most sophisticated cyber adversaries. Certified professionals demonstrate expertise in APT models, adversary emulation, Active Directory attacks, payload delivery detection, cyber deception, and data exfiltration defence.

What are the GDAT exam requirements?

The GDAT exam consists of 75 questions, is web-based and proctored, has a 2-hour time limit, and requires a minimum passing score of 70%. Proctoring is available via ProctorU (remote) or PearsonVUE (onsite).

Does GDAT cover adversary emulation and purple teaming?

Yes — adversary emulation is a core GDAT topic, covering how to plan and execute realistic attack simulations using MITRE ATT&CK-aligned techniques and how to run coordinated purple team exercises that improve defensive controls.

Who should pursue the GDAT certification?

GDAT is ideal for blue, red, and purple team personnel who want to understand advanced adversary tradecraft, security architects who design defences against sophisticated threats, IT administrators managing high-value environments, and threat hunters.

Does GDAT cover Active Directory attacks?

Yes — GDAT covers Active Directory attack and defence in depth, including credential attacks (Pass-the-Hash, Kerberoasting), lateral movement, domain persistence techniques, and defensive controls to detect and prevent domain-level compromises.

Does GDAT include cyber deception?

Yes — GDAT covers cyber deception as an active defence strategy, including deploying and monitoring honeypots, honeytokens, and deception assets to achieve early adversary detection and drive threat hunting workflows.
