The study analyses residential social service facilities as a component of civil defence and the internal stability of a democratic state. Based on a qualitative analysis of international strategic and legal documents and relevant scholarly literature, it demonstrates that continuity of care for vulnerable groups constitutes an important element of national resilience to hybrid and other contemporary threats. Key factors include crisis preparedness, the decision-making capacity of management, intersectoral coordination, and the professional training of staff. The text emphasises the need for their systematic integration into security and crisis planning.
