In the Microsoft 365 security center (now Microsoft 365 Defender), incidents are used to triage and investigate threats across the tenant. Microsoft’s security documentation explains that “an incident is a collection of related alerts” that are automatically correlated to give analysts a single, end-to-end view of an attack. Within each incident, the portal surfaces impacted assets such as devices, users, mailboxes, and applications, enabling responders to quickly identify which endpoints are affected by a given alert and to take response actions (isolate device, collect investigation package, run AV scan, etc.). This design allows security teams to move beyond individual alerts and instead work a consolidated investigation that lists affected devices in the incident’s Evidence & Response/Assets sections, complete with alert timelines and device details.

By comparison, Secure Score measures the organization’s security posture and recommendations; policies are configuration/enforcement objects (e.g., Defender or compliance policies) and are not the investigative view for alerts; classifications relate to information protection labeling rather than alert investigation. Therefore, to identify devices that are affected by an alert, you use the Incidents experience in Microsoft 365 Defender, where correlated alerts show the devices involved alongside the entities and evidence connected to the threat.
