Microsoft Security, Compliance, and Identity Fundamentals (SC-900)
Microsoft Security, Compliance, and Identity Fundamentals (SC-900) develops foundational knowledge of how organisations protect identities, data and cloud services. Microsoft currently describes the exam as spanning security, compliance and identity concepts and related Microsoft solutions across Azure and Microsoft 365.
The SkillsNest SC-900 course follows the same four exam areas shown in the curriculum on this page: concepts of security, compliance and identity; Microsoft Entra; Microsoft security solutions; and Microsoft compliance solutions. Typical ideas include Zero Trust, authentication and authorization, Microsoft Entra ID, Conditional Access, Azure security services, Microsoft Sentinel, Defender XDR, Microsoft Purview, compliance management, information protection, data lifecycle management, insider risk, eDiscovery and audit — without repeating the full lesson list below.
Typical learners include people starting a security or compliance path, IT professionals who need a shared vocabulary for Microsoft SCI solutions, and students preparing for a first Microsoft security credential. Holding the certification does not guarantee a job.

How to prepare
A practical SC-900 study loop using the course, practice bank and mocks on this page.
Step 1
Work through the published SC-900 course
Use the video lessons on this page to cover SCI concepts, Microsoft Entra, Microsoft security solutions and Microsoft compliance solutions. Follow the curriculum in order rather than skipping to isolated product names.
Step 2
Check understanding after each module
Use the published knowledge checks where they appear, then practise by topic. Spend more time on explanations for items you miss than on the raw score.
Step 3
Sit a timed SC-900 mock exam
Use a full-length mock under timed conditions to practise pacing. Registered users can start with the designated free mock when one is published, then return to weaker domains.
Step 4
Revisit weak areas before another mock
Go back to the course or practice bank for the topics that scored lowest — for example Conditional Access, Sentinel, Defender XDR or Purview — rather than repeating questions you already know.
