CyberDefenders serves as a training platform focused on enhancing the skills of SOC analysts, threat hunters, security blue teams, and DFIR professionals in cyber defense. It features two in-depth learning trajectories: the Certified CyberDefenders (CCD) course aimed at preparing individuals for performance-based certification and BlueYard’s engaging CyberRange labs that provide practical, hands-on experience. Users have access to a collection of realistic, browser-based blue team labs and exercises that require no installation or external setup, which are regularly updated to align with the most recent CVEs and attack reports. Each training module combines practical exercises with clear, step-by-step instructions, effectively linking theoretical knowledge with real-world application, thereby enabling participants to effectively manage threat detection, incident response, and forensic analysis activities. The performance-oriented tasks simulate authentic scenarios, empowering learners to excel in areas such as threat hunting, log analysis, malware investigation, and operations within a Security Operations Center (SOC). Additionally, this comprehensive approach fosters continuous improvement and adaptability in the ever-evolving landscape of cybersecurity.
