Mission Brief

CloudNova Technologies has been contracted by MedSecure Global, a multinational healthcare organization, to perform a comprehensive enterprise security assessment of its multi-cloud serverless platform.

The organization operates hundreds of serverless applications across AWS Lambda, Azure Functions, and Google Cloud Functions supporting patient management systems, financial services, healthcare APIs, AI platforms, IoT integrations, and enterprise automation.

Executive leadership requires an independent security assessment to validate security controls, identify business risks, evaluate operational maturity, and establish a strategic roadmap for improving the organization’s serverless security posture.

You have been assigned as the Lead Cloud Penetration Tester responsible for conducting the assessment and presenting executive-level findings.
