The article substantiates that the internal security level influences greatly the level of external security of the competitive status. Internal security is determined to become apparent through the productivity value of current costs, product quality, the degree of production capacities use and technical characteristics of equipment. External security of the competitive status should be assessed on the basis of determining the deficiency of the earnings before tax value which is short-received by an enterprise because of discrepancy between its market share and the share of a leading one. The developed indices underlie assessment of economic security of the competitive status of Ukraine’s mining enterprises. The methods suggested in the article are used for calculating the level of reserves of internal security of the competitive status for iron ore open pits of mining and concentrating works and demonstrate availability of considerable reserves at all open pits of Ukraine’s mining and concentrating works. At the same time, iron content in products of Ukrainian mining enterprises is known to be lower than that at foreign companies and the content of impurities does not meet international market requirements. Due to that, all Ukrainian enterprises are characterized by non-compliance of key indicators that describe their competitive status with threshold values. This testifies to inefficiency of economic security provision and management. To ensure the economic security of enterprises in the future, it is currently proposed to assess the level of digital maturity of the enterprise and, based on the data obtained, develop appropriate measures. These measures should include digitalization of all areas of the enterprise. It is proposed to introduce activities to digitize the value chain, equipment and mineral resources. Important indicators that provide information about the level of economic security in the future are the current level of use of big data and the level of digitalization of product promotion.
