The Microsoft Certified: Cybersecurity Architect Expert (SC-100) is Microsoft's highest security certification and targets experienced professionals who design security architectures for hybrid and cloud-native environments based on the Microsoft platform. It requires at least one associate-level security certification (e.g., AZ-500, SC-200, or SC-300) and builds on that knowledge. The certification addresses zero-trust architectures, compliance requirements, identity governance, and infrastructure protection from a strategic perspective. For organizations heavily invested in Microsoft 365 and Azure, SC-100 is valuable proof of expertise; outside the Microsoft ecosystem, its relevance is more limited. The exam will be updated in April 2026.
