Abstract. Introduction. Security is one of the main conditions of the enterprise. In today's market economy, the company operates in difficult, unstable and uncertain conditions. The characteristics of the company's ability to self-support and active development come to the fore, taking into account staff behavior, management relationships, stakeholder involvement in the discussion and decision-making process to identify risks, threats and minimize them. Purpose. The aim of the study is to analyze the essence of the concept of "security" and the composition of its structural components, as well as the feasibility of introducing human capital as a component of enterprise security and internal stakeholders of the enterprise. Results. It is presented that security threat means changes in the internal and external environment of the entity, which lead to negative changes in the security entity. The most common classification of security threats is their division into internal and external. It is noted that the classification of safety should be carried out by areas of enterprise management, which are often reflected in the organizational structure of management: environmental, social, legal, law enforcement, information, economic. It is noted that economic security is the most informative component, which reflects the consequences of all processes occurring during the operation of the enterprise. The study found that the most complex part of the security system is the person and the human factor can have a critical impact on business success. Conclusions. It has been studied that human capital is associated with employees and managers of the enterprise, which are the main source and generator of knowledge, part of the internal stakeholders of the enterprise. This capital at the same time requires appropriate investments in its development (investment) and contributes to the goals of the enterprise, forming added value. Our further research is relevant to assessing the level of impact of stakeholders in terms of investment in human capital. It is determined that part of the internal stakeholders of the enterprise (as human capital) occupies a leading place in the development resources of each organization and is therefore the main source of uncertainty, and the risks associated with some internal stakeholders can be identified as complex.
