- Microsoft did not publish a major blueprint redesign for SC-100 in 2026.

2026 Exam Refresh
Microsoft’s current SC-100 study guide shows a January 22, 2026 refresh.
The important signal from the change log is that the blueprint is stable:
- No major domain reshaping across the four core architecture areas
- Minor changes called out in identity and access content
- Minor changes called out in endpoint content
- The same core architecture themes remain: Zero Trust, resilience, SecOps, hybrid identity, compliance, infrastructure protection, application security, and data governance
In practice, this means older prep is not worthless, but it can drift on naming and emphasis. Your study plan should use current Microsoft terms such as Microsoft Entra, Microsoft Defender XDR, Microsoft Defender for Cloud, Microsoft Purview, Azure Arc, External Attack Surface Management, and Copilot for Microsoft 365 governance.
