The purpose of this study is to develop the Counterintelligence Strategy as a conceptual document in the field of state security of Ukraine, identifying current security threats to Ukraine, which global landscape has been significantly transformed since the adoption of the Law of Ukraine “On Counterintelligence”, is substantiated. It is proved that the provisions of such Strategy should determine the current and projected counterintelligence environment via a set of the following elements. The nature of real and potential threats in the process of implementing state foreign and domestic policy course determined by Ukraine. Sources of such threats (individual states and their intelligence agencies, terrorist organizations, transnational organized crime, etc.). Features of the identified encroachment objects of foreign intelligence agencies, terrorist and other criminal organizations, including transnational ones. Long time strategy treats like COVID-19 pandemic. During the past decades of the XXI century, intelligence has become a crucial tool in the system of determining and implementing the foreign policy in international relations. Modern realities confirm that this political and legal phenomenon directly affects the formation of the foreign policy course of any state, the development of its geopolitical strategy and defense doctrine. Possessing a powerful apparatus for obtaining primary information, fulfillment of government orders for monitoring, evaluation, analysis, forecasting and modeling of possible scenarios of global- or regional-scale events and processes, special services take an active part in perspective and current foreign and domestic policy implementation. Thus, based on the state security paradigm, which cannot be defined in the absence of threats and ensured by their complete elimination, since negative factors for state security objects will always exist, the ensuring of its development requires first of all creation of the conditions under which threats will not be able to limit its development. That is why it is necessary not only to minimize the impact of such factors on vulnerable objects, but also to create a certain “immunity” to their impact, i.e. the ability of the state security system to function effectively in spite of the negative impact. Thus, maintaining the ability to function in terms of the existing threats is the most important area of practical activity for the state security protection, as well as ensuring the legitimate interests of the state. During the paper decades of the XXI century, intelligence has become a crucial tool in the system of determining and implementing the foreign policy in international relations. Modern realities confirm that this political and legal phenomenon directly affects the formation of the foreign policy course of any state, the development of its geopolitical strategy and defense doctrine.
