The present research analyses the cybersecurity threats to Kenya's banking sector with special reference to the Central Bank of Kenya. Since the banking sector is one of the vital parts of Kenya's economy, these entities have become vulnerable to cyber threats that negatively impact financial information accuracy, businesses' solvency, and customers' trust. The research thus uses a holistic research strategy to analyze and determine the major challenges CBK has faced in its effort to supervise and respond to cybersecurity challenges in the financial sector. In a quantitative research approach, the study employs questionnaires, documents, and interviews to gather data from 278 participants, the respondents being the CBK employees, regulating authorities, and policymakers. The research also shows that regulatory compliance plays a large role in determining banking sector stability, with 65 percent stating high compliance difficulty. Mobile banking and competition from the fintech sector involve losses and gains in operational efficiency and preparedness for the future. Moreover, there is a positive significant relationship between the level of cybersecurity readiness and customers' trust. Thus, the study concludes that cybersecurity issues are best solved through compliance, technology, and security management approaches.
