This article analyses the issue of systemic state security in the context of contemporary threats of a complex and dynamic nature. The adopted research hypothesis assumed that effective development of systemic resilience requires cooperation between public administration, the private sector, non-governmental organisations, and citizens, alongside the development of adaptive mechanisms. The study applied a literature review method, supplemented by references to the experiences of selected countries, with particular emphasis on the Finnish model. The analysis indicated the key importance of social trust, institutional flexibility, and broad cross-sectoral cooperation in shaping the long-term resilience of the state to systemic threats.
