Abstract: The paper analyses the complex and multidimensional role of the accounting professional within the modern mechanisms for preventing, identifying, and managing financial fraud. In an economic context marked by accelerated digitalisation and increasingly sophisticated financial risks, the accountant becomes an essential actor in strengthening organizational integrity. The study addresses the main types of fraud, the applicable regulatory and ethical framework, as well as the specific internal control and risk assessment tools. The accounting responsibilities in detecting fraud signals, collaborating with auditors, and participating in financial investigations are highlighted. At the same time, the paper emphasizes the need for continuous development of professional skills, especially in the field of modern technologies, in data analysis, and in post-detection situation management. The conclusions highlight the decisive contribution of the accountant to protecting the financial ecosystem and promoting an organizational culture based on ethics and transparency.
