Cybersecurity threats continue to evolve, requiring a shift from technical defenses to behavioral strategies within the broader context of Information and Communication Technologies (ICT) and global development. This study examines how intrinsic (ICMS) and extrinsic (CMES) motivation influence cyber threat awareness and response (CTARS), drawing on Self-Determination Theory (SDT) and Protection Motivation Theory (PMT). Using Structural Equation Modeling (SEM) on survey data from 140 MIS employees in ESG-driven organizations, the study highlights cybersecurity’s role in sustainable ICT governance. Findings show that intrinsic motivation is the strongest predictor of cybersecurity engagement, while external reinforcements play a secondary role. Organizations fostering autonomy, responsibility, and mission-driven security cultures report fewer incidents and lower financial losses. These results support motivation-driven cybersecurity approaches that align with ICT resilience, crisis management, and sustainable digital security. This research bridges cybersecurity, psychology, and ICT governance, offering actionable insights for policymakers and security leaders to enhance long-term digital resilience and crisis preparedness.
