The major results of the study can be considered determining the hierarchy of influence of each of the threats affecting the corporate security of industrial enterprises, which will allow optimizing the security system and directing its activities to more pressing issues. Our method of the hierarchical organization of threats to corporate security does not take into account the specifics of the corporate security system of industrial enterprises in most European countries and now can be freely implemented mainly in industrial enterprises of Eastern Europe. The proposed method of assessing external and internal threats is currently optimized for the activities of industrial enterprises in Eastern Europe, including Ukraine and Poland.

The relevance of this study lies in determining the level of threats that affect the corporate security of industrial enterprises. The methodology for assessing the level of influence of these threats is universal, therefore it can be used in the event of a change in the main threats, it is extremely relevant in the context of rapid globalization changes in the world.
