Following the war waged against radical terror under the leadership of United States of America upon the September 11 attacks, a remarkable increase has been recorded in private companies’ significance and roles in intelligence system. Due to changing threat perceptions, threats’ becoming asymmetrical and increased demands for risk analyses required by global companies for their international investments, private intelligence companies have entered into a major development process. In this period, completely profit-oriented private intelligence companies have gained a wide-ranging movement area through occasional support and guidance of intelligence services of their country. In addition to this, for recent years, thanks to the developing economic strengths and intelligence network of the given companies, they have almost begun to work as an intelligence service and provide services to their customers. As a consequence, it is evident that private intelligence companies will play a crucial role in intelligence management of the future. In this respect, this study will primarily examine the roles of private intelligence companies in the USA’s intelligence system where they efficiently operate, and problems they arise. And thus, functions of private intelligence companies, whose influence on intelligence management will rapidly enhance, within the USA’s system will be analysed and therefore, on global scale, efficiency of such kind of companies on future’s intelligence management will be revealed.
