Abstract
<jats:p>Problem statement. Digitalization and the rapid expansion of online communications have fundamentally transformed the mechanisms of corporate reputation formation. In the digital environment, business reputation becomes highly sensitive to information signals, while the speed of content dissemination amplifies both positive and negative reputational effects. Under these conditions, digital marketing becomes a key instrument for managing reputational risks, stakeholder trust, and brand resilience. Traditional marketing communication approaches are no longer sufficient to ensure reputational security and require an integrated digital and analytical framework. Research objective. The objective of the research is to provide a comprehensive analysis of the role of digital marketing in forming business reputational security and to generalize international cases of using digital marketing tools to strengthen reputational resilience. Object of the research. Business reputational security as a component of enterprise economic security under digital transformation conditions. Methods used in the research. The study applies methods of analysis and synthesis, logical generalization, systemic approach, comparative analysis, case study method, classification and structuring, as well as tabular and graphical tools for presenting international practices. Basic research hypothesis. Systematic use of digital marketing tools, analytics, and online monitoring is a decisive factor in forming and maintaining business reputational security in conditions of global digital competition. Presentation of the main material of the research. The paper defines reputational security as the company’s ability to maintain trust and a positive image in the digital environment. Key digital marketing instruments (SMM, SEO, content marketing, ORM, targeted advertising, analytics) are systematized in terms of their reputational impact. Positive and negative international cases are analyzed to demonstrate how digital communications influence reputational resilience. The roles of transparency, ethical marketing, personalization, and crisis response are highlighted. Modern challenges such as cyber threats, fake content, data ethics risks, and algorithmic bias are identified, along with directions for adapting international experience for Ukrainian businesses. Originality and practical significance of the research. The study proposes a systemic approach to considering digital marketing as a reputational security tool. International cases and digital risk-management instruments are structured for practical use in strategic and communication management. Conclusions and prospects for further research. It is proven that digital marketing acts as an integrated mechanism for building reputational resilience. Key conditions include transparency, ethical data use, systematic online monitoring, and crisis readiness. Further research should focus on quantitative models for assessing reputational risks and the use of artificial intelligence tools for forecasting them.</jats:p>
