<p><em>The rapid adoption of multi-cloud environments, where organisations simultaneously use two or more cloud service providers, has introduced a complex and layered cyber risk landscape that existing single-cloud governance frameworks are not equipped to manage. This is particularly acute in Nigeria, where banking, education, healthcare, and government institutions are increasingly dependent on cloud infrastructure yet lack a unified governance approach that applies consistently across all providers in use. This study addresses that gap by developing and validating the Cyber Risk Governance Framework for Multi-Cloud Environments (CRGF-MCE), a structured, empirically grounded, and mathematically validated governance model. A descriptive survey design was adopted, and a structured 33-item questionnaire was administered to 100 respondents drawn from Nigerian organisations operating multi-cloud environments across multiple sectors. Three differentiated Likert-type scales were used across five thematic sections covering cloud adoption, cyber threat monitoring, governance structures, risk controls, and governance challenges. A one-sample t-test was applied to test the hypothesis that significant cyber threats exist in multi-cloud environments. The hypothesis test produced a t-statistic of 17.09, far exceeding the critical value of 1.645 at α = 0.05, confirming the significant presence of seven threat categories, including misconfigurations, IAM weaknesses, insider threats, and unified visibility gaps. The CRGF-MCE was developed, comprising five integrated components and four governance layers, namely Identity and Access Management, Logging and Monitoring, Compliance Enforcement, and Policy Orchestration and was validated with a Model Validation Score of 0.7743. The framework provides Nigerian organisations with a replicable, scalable, and continuously adaptive governance system for multi-cloud environments.</em></p>
