The increasing demand for sustainable IT practices and resilient cybersecurity strategies has highlighted the need for multidisciplinary education to develop skills at the intersection of virtualization, cybersecurity, and green IT sustainability. This study presents the design and piloting of a nano-credential tailored for learners from non-IT disciplines, equipping them with essential competencies in these fields. The curriculum employs a blended pedagogical approach, integrating interactive, problem-based, and exploratory learning to enhance engagement and practical skill development. A structured evaluation process was conducted, involving expert validation and learner piloting. Experts confirmed the curriculum’s relevance, structure, and pedagogical soundness, while learners reported an increase in their understanding of sustainability, virtualization, and cybersecurity. The study identifies key challenges in multidisciplinary education, particularly in bridging technical and non-technical domains. Additionally, it highlights the value of modular and flexible learning pathways, demonstrating how multidisciplinary nano-credentials can bridge skill gaps across disciplines. This work serves as a practical use case for educators, illustrating how to integrate interrelated sustainability and technical-focused topics, aligning learning outcomes with global sustainability goals. By fostering both a sustainability-oriented mindset and technical proficiency, this approach empowers individuals to contribute effectively to cybersecurity and environmental sustainability efforts at organizational and global levels.
