As organizations accelerate digital transformation, the security of cloud-native applications has become a national and enterprise priority. This article critically explores the Secure-by-Design paradigm within the Microsoft cloud ecosystem, emphasizing how DevSecOps methodologies, integrated toolchains, and regulatory frameworks converge to embed cybersecurity from code inception to production deployment. Anchored in the principles of least privilege, defense in depth, and secure defaults, Secure-by-Design offers a scalable blueprint for mitigating the risks of cyber threats in Azure and Microsoft 365 environments. Through case studies, the paper highlights practical implementations of GitHub Advanced Security, Microsoft Defender for Cloud, Azure Policy, and Purview to enforce compliance, identity protection, and continuous threat monitoring. It further examines the cultural, technical, and geopolitical challenges in secure cloud adoption and offers strategic recommendations for enterprises and national cybersecurity stakeholders. Finally, this study reaffirms that embedding security across the application lifecycle is a best practice as it serves as an essential to safeguarding critical infrastructure in an era of increasingly complex digital threats.
