This research investigates the management of cyber incident risks in e-business environments with an emphasis on reducing financial losses and reputational impact. The increase in digitization in the business world correlates with the rise of cyber threats that can cause significant financial losses as well as long-term reputational damage. This systematic review evaluates recent research (2022-2025) from various academic databases such as PMC, IEEE Xplore, ScienceDirect, and Scopus. The aim of this study is to discover effective risk management tactics, rapid incident response mechanisms, and ways to mitigate financial and reputational losses in e-business. The literature review highlights the importance of having a comprehensive risk management framework, a direct threat monitoring system, and a planned reputation recovery strategy. Research findings indicate that a proactive approach to cyber risk management not only functions to protect financial assets but also to maintain consumer trust and business continuity. Cooperation among stakeholders such as technology, management, and regulators is key in creating a cyber-resilient e-business ecosystem.
