The adoption of multi-cloud strategies is increasing as businesses look to take advantage of the diverse offeringsfrom different cloud providers. However, managing security policies consistently across multiple cloud platformspresents a significant challenge. This paper introduces a framework for automated cross-cloud securityorchestration, ensuring consistent security policy enforcement across multi-cloud environments. By leveragingautomation, the proposed framework enables the dynamic enforcement of security policies, reducing human errorand increasing operational efficiency. We discuss the key components of the framework, including policydefinition, orchestration layers, and compliance management. A case study is presented to demonstrate thepractical implementation of this framework in a typical enterprise scenario. The results show that the proposedframework not only simplifies security management in multi-cloud environments but also ensures compliancewith security standards and regulations. Finally, the paper outlines future directions for extending the frameworkto incorporate emerging technologies such as AI and machine learning for enhanced security.
