MCS case studies
MCS · Put your knowledge to work in context.
SC-900, officially Microsoft Certified: Security, Compliance, and Identity Fundamentals, is an entry-level credential that confirms you can describe how Microsoft's cloud security stack fits together rather than configure it. It suits people moving into security, compliance, or identity work; sales and pre-sales staff who need credible vocabulary; IT generalists whose duties now touch Microsoft Entra, Defender, or Purview; and students building a first certification path toward the associate-level security exams. The MCS case studies are 5 cases and about 4,055 words.
