What is Microsoft Certified Systems Engineer (MCSE)?

Microsoft Certified Systems Engineer (MCSE) was a certification offered by Microsoft that validated expertise in designing, implementing, and managing IT infrastructure solutions based on Microsoft technologies. While the original MCSE certifications have been retired, the name might be used informally to refer to professionals with extensive Microsoft infrastructure skills or to the current, role-based certifications. Historically, MCSE professionals were sought after to manage servers, networks, and systems in enterprise environments. The current role-based certifications validate skills related to Azure, Microsoft 365, and other modern Microsoft technologies.
