 Maintaining security in a cloud operations platform landscape is a monumental task. These landscapes often consist of numerous services, each comprising multiple components like images, databases, libraries, and configurations. 
 The challenge is compounded by the fact that these components have varying versions and can be shared across multiple services, creating a critical need to pinpoint a component's specific instance (version) as the security baseline. Therefore, vulnerabilities of a single component can impact multiple services within the landscape.

 ### Compliance and Efficiency
 Meeting compliance requirements and maintaining robust security standards is time-consuming and resource-intensive due to the lack of centralized visibility into the intricate relationships and dependencies between services and their underlying components and configurations.
 This makes tracking remediation, documenting evidence, and managing security configurations difficult leading to inefficient security operations and delayed remediation efforts.
