Explanation:

Microsoft positions Compliance Manager as a capability available inside the Microsoft 365 Compliance Center (now Microsoft Purview compliance portal). In Microsoft's SCI learning content, Compliance Manager is described as the centralized workspace in the compliance portal that "helps you manage your organization's compliance requirements," providing a compliance score, pre-built and custom assessments, and improvement actions you track and assign. The documentation explains that admins "use the Microsoft
365 Compliance Center to access Compliance Manager," where they can review the score, map controls to regulations and standards, and manage evidence and testing of controls. It also clarifies that Compliance Manager is surfaced directly in the compliance portal navigation, enabling authorized roles (such as Compliance Administrator, Global Administrator, or Compliance Data Administrator) to open the Compliance Manager blade to create or view assessments, assign actions, and review detailed guidance. By contrast, the Microsoft 365 admin center focuses on tenant, billing, and user management; the Microsoft 365 Defender portal focuses on security operations and threat protection; and the Microsoft Support portal is for service requests. Therefore, the direct and intended entry point for Compliance Manager is the Microsoft 365 Compliance Center.
