5.3. Implement Microsoft Security Copilot

💡 First Principle: Security Copilot doesn't generate its own security data — it's a natural-language interface and reasoning layer over the data already sitting in Defender for Cloud, Sentinel, and other connected sources, which means its usefulness depends entirely on what it's been configured and permitted to access.

Mental model: think of Security Copilot as an accelerant for the investigation and response work an analyst would otherwise do manually across multiple portals — it doesn't replace Defender for Cloud or Sentinel, it summarizes, correlates, and suggests next steps by querying them on the analyst's behalf.

⚠️ Common Misconception: Security Copilot plugins do not work automatically the moment Copilot itself is enabled. Plugins must be explicitly enabled and often require specific permissions or roles configured before Copilot can query that data source — Microsoft agents and Security Store agents each have their own separate enablement step as well.
