S + ESG as a New Dimension of Resilience: Security at the Core of Sustainable Business Development

This study introduces the SESG (Security, Environmental, Social, Governance) framework as a necessary evolution of traditional ESG, aimed at enhancing societal and corporate resilience in the face of hybrid threats, war, and climate crises. By integrating a security dimension, SESG responds to the growing inadequacy of classical ESG models in high-risk environments, particularly for countries like Ukraine. The research combines theoretical analysis with empirical data, including a nationwide survey of Ukrainian professionals across business, government, and civil society sectors. The findings reveal overwhelming support—over 90%—for incorporating security into ESG, especially in sectors such as IT, energy, and logistics. The article proposes a matrix of qualitative and quantitative indicators to assess SESG performance and highlights business-led contributions to national defense. The results demonstrate that security is not just a governmental concern but a key factor in corporate responsibility, investor trust, and sustainable development. The study concludes that SESG offers both a scientific reframing of resilience and a practical tool for policy and strategy, particularly under conditions of geopolitical and environmental instability. It urges cross-sector collaboration, standardization, and awareness building to embed SESG as a core principle in global sustainability agendas.
