Understand the Microsoft Copilot ecosystem first The key is to understand that Microsoft 365 Copilot, Microsoft Security Copilot, and Power Automate are different layers of the solution.
1. Microsoft 365 Copilot Productivity + Work data Works with Microsoft 365 work content such as emails, meetings, documents, chats, and files that the user is authorized to access. Useful for summarization, drafting, analysis, and work-related queries. 2. Microsoft Security Copilot Security operations + Investigation Helps security teams investigate threats, analyze incidents, understand identity/device risks, and work with enabled security data sources such as Defender, Entra, Intune, and Purview. 3. Power Automate + Copilot Workflow automation Converts business requirements into flows, helps create expressions, and supports workflow development. The flow executes configured actions through connectors, APIs, and permissions.
Microsoft Security Copilot integrates with Microsoft security products, while the Microsoft 365 Admin agent supports natural-language administration across supported Microsoft 365 scenarios. Admin-agent write or execute actions require explicit confirmation
Important: Copilot is not a universal command line for every Microsoft 365 workload. A prompt can only return data that the selected Copilot experience, its connected data sources, your permissions, and available capabilities support. For example, Intune Copilot can explore supported Intune data and troubleshoot devices, but it does not automatically provide every possible tenant-wide report
