The technology development in today's world is certainly a phenomenon that influences all spheres of human life, and thus safety. The first chapter, is defining security, national security, and the threats and security challenges in today's world full of unpredictabilities. The second chapter analyzes and defines the term of disruptive technologies, citing examples of history that were a threat to national security and which had the characteristics of disruptive technologies. Also, the second chapter analyzes some disruptive technologies of today and the near future with an emphasis on artificial intelligence. After defining the terms, one comes to the main part of the paper based on the analysis of strategic and security documents of large states, examining whether they recognized the problem and how they defined it. One analyzes how the Republic of Croatia has approached this phenomenon and what is the role and position of the Republic of Croatia when it comes to new technologies. The purpose of this paper is to identify disruptive technologies, to explain them and to show their significance for the security of countries with the emphasis on the Republic of Croatia. Finally, the goal is to clearly define the position of the Republic of Croatia in the global community regarding the disruptive technology. Thus emerged the two research questions that this paper will endeavor to provide the answer: 1 Is the concept of disruptive technology treated as a security issue? 2 Are disruptive technologies in the Republic of Croatia recognized and defined as a security issue?
