This study examines the intersection between circular economy (CE) practices and cybersecurity measures, analyzing their strategic implications for stakeholders and proposing directions for future research. A systematic literature review of peer-reviewed articles, reports, and case studies from 2014 to 2024 reveals that cybersecurity is essential for protecting the digital infrastructure supporting CE practices and serves as a strategic asset that enhances the resilience and sustainability of business models. Key challenges include securing complex supply chains and ensuring robust data protection. Opportunities lie in leveraging digital technologies to foster sustainable business models and developing regulatory frameworks that support secure CE practices. Strategic recommendations emphasize a holistic approach to integrating cybersecurity, supportive policies, and secure technologies. Future research should focus on empirical studies of cybersecurity effectiveness in CE and interdisciplinary research bridging environmental science, cybersecurity, and business management.
