GEIR is built for incident response team leads and advanced practitioners, threat hunting professionals, experienced digital forensic analysts, and enterprise detection engineers. Federal agents, law enforcement professionals, and SANS DFIR alumni looking to apply their forensic skills at enterprise scale are also a strong fit. FOR608, the course that prepares you for it, is aimed at DFIR, incident response, and threat hunting professionals at medium to large organizations who are already comfortable with core forensic and incident response fundamentals. 

FOR608: Enterprise-Class Incident Response & Threat Hunting prepares you for the GEIR exam. The course moves through six sections and 20 hands-on labs covering enterprise-scale detection, Windows and Linux DFIR, macOS and container analysis, and cloud incident response in Microsoft 365 and AWS, closing with a multi-platform capstone exercise. FOR608 assumes prior DFIR experience or completion of FOR500 or FOR508, since it skips introductory forensic material to focus on scale.
