Abstract: This article is devoted to the analysis of the influence of international non-governmental organizations on the development of civil society institutions in individual national states in the context of the processes of ensuring national security in these countries. The authors note that the XXIst century is characterized by the rapid development of international non-governmental organizations, whose activities are aimed at the emergence, support and development of civil society institutions in individual national states. However, not all civil society institutions, stimulated by international non-governmental organizations, are useful for the processes of preservation and development of society and the state. A significant part of them act as a tool to undermine the national security of individual States. In this regard, the national legislation of individual countries establishes norms that counteract, on the one hand, the possibility of creating and functioning such civil society institutions, and on the other hand, their subordination to international non-governmental organizations. The following methods of scientific research are used, in particular: formal-logical; comparative-legal; historical-legal; statistical; sociological; method of analyzing specific legal situations. The empirical basis of the study was made up of: international and national normative legal acts; materials of the scientific doctrine of civil society, international non-governmental organizations; materials of the practical activities of civil society entities (subjects of public control). The paper analyzes the main problems (on the example of Russia) related to countering the processes of using civil society institutions by international non-governmental organizations as a tool to undermine national security, among which one can single out: the lack of a comprehensive mechanism in Russia to counter the processes of using civil society institutions as a tool to undermine national security; the absence of criteria in legislation for attribution international governmental organizations and their branches (representative offices) belong to the above-mentioned category; weak control over them by public authorities; lack of specialized subjects of public control in this area; weak use of modern digital technologies in this area; lack of special criminal law structures to punish persons engaged in the above-mentioned activities. The authors have developed and justified a system of measures to resolve these problems.
