Business conditions, which are characterized by high turbulence of changes in the operating environment for all enterprises, have become significantly more complicated within the last year, which was catalyzed by the latest pandemic COVID19. In order to stabilize the situation and save the lives of citizens, a number of restrictions were applied, which also affected business activities. It is wrong to consider only this factor as the main one that affected the financial security of industrial enterprises. Other external factors for the formation of adequate protective redoubts should not be ignored. In addition, the specifics of the functioning of each individual enterprise, which is characterized by the excellent influence of macro-, meso- and macro-level factors, need attention. The aim of the study was to form a methodological approach to determining the impact of external factors on the management of financial security of industrial enterprises. To form a methodological approach to determining the impact of external factors on the management of financial security of industrial enterprises used methods: multi-criteria choice of alternatives based on a fuzzy relationship of preference - to determine the priority of the impact of individual factors on financial security; abstract-logical - for theoretical generalizations and conclusions of the study. External factors that most significantly affect the financial security of industrial enterprises include: the onset of the financial crisis and the rapid devaluation of the national currency; unpredictable political events; Military conflicts and terrorist acts; natural disasters and catastrophes (including the COVID19 pandemic); the emergence of a monopoly structure in the market; raider capture; application of trade and financial sanctions; full or partial blocking of bank accounts. The systematization of external factors influencing the financial security management of industrial enterprises has been carried out, which involves the application of the method of multi-criteria selection of alternatives based on a fuzzy ratio of advantages, which allowed to justify priority areas for improving financial security management. The obtained results create the necessary analytical basis for the improvement of the management system based on the introduction of adaptive and antisipative types of financial security management of industrial enterprises.
