It is noted that in modern conditions of instability, contradictions of reformation processes one of the most important tasks of economic science and practice is the development and implementation of an integral part of economic security – security system of enterprises and organizations, which must be represented by a set of organizational, legal, socio-economic, and managerial decisions that provide effective protection against external and internal threats and promote progressive development in the interests of the national economy. The formation of a market economy has objectively put the vast majority of domestic enterprises and organizations in front of the need to create a system of economic security that can reduce the level of threats to activities in key financial and economic areas. The purpose of the article is to study the methodological views on the essence of economic security and methods of its assessment, as well as to develop a model of integrated assessment of the level of the enterprise economic security. The methodological basis of the study are the scientific works of the classics of economics, works and publications of leading scientists and specialists who study the economic security of economic entities, combining theoretical and scientific methods: analysis, synthesis, theoretical and logical generalization. The analysis of approaches to the interpretation of the "economic security" concept is carried out and it is determined that the studied definition is multifaceted and complex and includes: the state of protection from unwanted changes (threats); efficient use of resources to prevent threats; system and the presence of competitive advantages that allow to achieve the main goals of the enterprise; the ability to reproduce and ensure the viability of the firm regardless of the instability of the external and internal environment; creating conditions and ensuring sustainable operation, progressive scientific, technical and social development, ensuring financial and commercial success. Based on a systematic approach, a model of integrated assessment of the level of the enterprise economic security is suggested, which allows to assess not only the state of the object of study, but also the development trend. For the methodical formation of an objective assessment of the integrated level of the enterprise economic security, the necessity of using a system of indicators for production and sales, personnel, technical and technological, financial component is substantiated. Based on the suggested model, the current and forecast level of economic security of such enterprises as PJSC "Hartron", PJSC "Datagroup", PJSC "Kyiv Radio Plant" was determined. Prospects for further research are the approbation of the model for business entities of different industries, different organizational and legal forms of ownership in order to identify the features of the assessment and refinement of the model.
