The primary goal of the study is to form an effective model for countering external threats to the corporate security of engineering enterprises in the context of COVID-19. The priority of forming a methodological basis for ensuring the corporate security of enterprises today is determined primarily by two key circumstances. First, is the need to create safe conditions for development under the influence of COVID-19. Secondly, the importance of the role of corporations functioning today, which they already play in economic processes. The modeling methodology was applied to show the functioning of the system for counteracting external threats to the corporate security of engineering enterprises in the context of COVID-19. COVID-19 has had a significant impact on the activities of engineering enterprises around the world, especially concerning foreign economic activity. Because of the study, the main stages and processes of countering external threats to the corporate security of engineering enterprises in the context of COVID-19 were identified.
