During the digitalization process, the activities and work carried out within organizations have also begun to be digitalized. In this process, the activities, legal responsibilities, and organizational processes of digital organizations have also begun to differentiate in the field of international law. With digitalization in international law, the legal responsibilities of states in the international arena, the legal procedures and rules they must comply with, and the powers and areas of responsibility of states are being redefined. As organizations transform from traditional to digital, the process of digitalization also emerges in the legal arena. In this digital age, the free flow of data, the most fundamental raw material for organizations' activities and all their processes, is a fundamental element of international trade and communication. In this process, the concepts of digital information and data flow emerge. This study examines the transformation experienced in international law with digitalization and the new legal responsibilities that have emerged. The study examines cybersecurity, transboundary data flows, digital human rights, and the digitalization policies and practices of international organizations. This study aims to reveal the impacts of the digitalization process on international legal norms and to offer reform proposals in this direction.
