The research is aimed at substantiating new approaches to the formation of the system of economic security and its components, in particular the financial component, in order to ensure the integrity of the system from the point of view of the possibility of effective functioning in new economic conditions, characterized by changes in the forms of interaction of industry with the banking system, the tax system; changes in the state policy, which complicate the mechanism of interaction with business structures. It is proved that the financial security of an enterprise is central to the system of economic security, which is explained by the following: the level of financial security of any enterprise determines its ability to provide other components of its economic security, and changes in any field of the enterprise are ultimately reflected in its financial security.
