This article examines international approaches to combating corruption, characterized by a shift from the formal requirement to implement compliance programmes to the need to demonstrate their actual effectiveness — the updated standards of the OECD (2021) and the World Bank Group (2025), which introduce the principle of proportionality, differentiating requirements for anti-corruption systems depending on the size of the organization. It presents data derived from official Russian statistics (the Register of Persons Dismissed Due to Loss of Trust and the Unified Register of Procurement Participants for 2024–2025), demonstrating the high vulnerability of small and medium-sized businesses to corruption risks and the insufficiency of existing internal control measures. Approaches to the regulation of anticorruption compliance in Brazil, the United Kingdom, Portugal, the United States, and France are analyzed, revealing a general consensus regarding the core elements of compliance, despite significant differences in the degree of regulatory detail and assessment methodologies. Particular attention is paid to the introduction of digital technologies (artificial intelligence, electronic platforms) in the activities of supervisory authorities and corporate compliance systems, as well as to issues of jurisdictional arbitration and the conduct of expert examinations by public authorities. The article formulates proposals for improving Russian legislation, taking into account best practices in the implementation of anti-corruption compliance in foreign countries.
