This whitepaper presents a zero-trust approach to securing multicloud environments, where no user or system is inherently trusted. It explains that traditional perimeter-based security models are ineffective in distributed cloud architectures and outlines key risks such as data breaches, account hijacking, misconfigurations, and supply chain attacks. The paper emphasizes understanding shared responsibility models across cloud providers and implementing strict identity and access management controls. It details how zero-trust principles—continuous verification, least-privilege access, and strong authentication—can mitigate these risks. Additionally, it provides a structured framework for building a cloud security program, including asset inventory, microsegmentation, policy enforcement, and
