Microsoft 365
Microsoft SC-900
Cloud adoption spreads security, identity, and compliance work across help desk staff, sysadmins, and compliance stakeholders who often lack a shared vocabulary. When terms like Zero Trust, least privilege, and the shared responsibility model mean different things to different people, risk discussions stall and audit conversations take longer than they should. This entry-level SC-900 course gives IT Directors and Training Managers a single baseline to assign across the team. Learners cover Microsoft Entra ID (Azure AD) identity concepts, authentication and self-service password reset, Microsoft Defender threat protection, Intune endpoint security, and Microsoft Purview capabilities such as sensitivity labels, DLP, eDiscovery, audit, data lifecycle management, and insider risk. The course stays conceptual, with walkthroughs in Azure, Microsoft 365, Intune, and Purview, so new hires, help desk technicians, and non-technical risk stakeholders can all take part. After completion, your team can explain Microsoft security terminology to technical and non-technical audiences, identify which Microsoft tool fits a given identity, threat, or compliance use case, and route questions to the right platform capability or specialist team. The course also provides a structured review of the fundamentals covered by the SC-900 certification exam. At about 21.7 hours across 25 skills, the course fits an onboarding cohort or a team certification push. Team Leads can bundle it into Playlists, and Training Managers can track per-learner progress and completion with Team Reporting before moving the team on to role-based Microsoft security training.
