The relevance of the topic of the dissertation research is due to the need to increase the level of economic security of insurance companies, which will contribute to their stable development, ensuring financial stability and competitiveness in the market of insurance services. Complex diagnostics, which includes the analysis of internal and external factors, will allow timely identification of potential threats and taking adequate measures to neutralize them. The theoretical-methodological provisions and practical recommendations for the formation of complex diagnostics substantiated in the dissertation work are a further deepening of the process of solving the scientific and practical task of ensuring the economic security of the insurance company in order to improve the efficiency of its activities. The main results reflecting the scientific novelty are as follows: for the first time: a model for the integrated assessment of the level of economic security of an insurance company was developed, which involves expert determination of a list of indicators from functional components that reflect the state of economic activity of an insurance company, with the aim of taking into account and calculating each of them. This will ensure the comprehensiveness, predictability and objectivity of the assessment of economic security, and the integrated nature of this model will allow to reduce possible risks and improve the strategic management of the financial stability, reliability and competitiveness of the insurance company; improved: the essence and content of the concepts "economic security of the insurance company" and "diagnosis of the economic security of the insurance company". At the same time, the economic security of an insurance company should be considered as a state in which it can ensure stable and effective functionality in production, financial and investment processes in the face of risks arising from external and internal factors, while ensuring stable income, compliance with legislative and regulatory requirements, as well as protecting the interests of insurers while maintaining the trust of clients and partners. And a comprehensive diagnosis of the economic security of an insurance company is a systematic and comprehensive examination of all aspects of its functioning, and includes an analysis of financial, economic, managerial, informational and other aspects of the company's activity in order to obtain a deep understanding of the current state of the company, identification of problems that threaten its financial state, business reputation and ability to perform their functions in accordance with legislation and international standards, and capabilities, as well as development of strategies and measures to ensure economic security. This allows for a more objective assessment of the level of economic security of the insurance company and contributes to the formation and effective implementation of complex diagnostics in ensuring the economic security of the insurance company; a list of functional components of the economic security of an insurance company, namely market, financial, personnel, political-legal, social-psychological, informational-analytical, organizational, which, in comparison with the traditional approach, allows for a comprehensive diagnosis of the state and level of economic security by groups of indicators , taking into account the specifics and features of the insurance company's activity; a tool that contributes to effective risk management, namely a multifactor regression model, which, unlike the existing ones, will provide an opportunity to respond in time to the influence of external and internal factors on the economic security of the insurance company and to detect possible changes in the level of economic security, namely changes in the integral index of economic security insurance company in the future; received further development: modern concepts of insurance company diagnostics, which help to systematize and consider the processes of managing and ensuring the economic security of insurance companies from different points of view, which takes into account the specifics of each of them and allows scientists and practitioners to choose approaches that best meet the specific requirements and conditions of their activities; a system of complex diagnostics of economic security, which, unlike the existing ones, will solve on an ongoing basis the entire complex of tasks related to business protection and protection of the interests of the insurance company; interpretation of the features of the state and development trends of the country's insurance industry, analysis of the state and level of economic security of the insurance company, which fully takes into account its financial and economic features and specialization; methodological approaches to the selection and application of indicators of comprehensive diagnostics of economic security, which make it possible
