Knowledge Base & Operational DocumentationHow to Investigate a Security Alert for a New Login From an Unmanaged Device
A login from an unmanaged device can be legitimate or indicate stolen credentials. The account may be protected by MFA while still accessing data from an endpoint outside the organization’s controls.
What to check
Confirm user and device context, authentication strength, access policy, data viewed or downloaded, session lifetime, and whether the device is newly registered. Compare with recent support requests and travel.
Recommended next step
Apply the organization’s conditional access and incident procedures, revoke sessions if unauthorized, and help the user enroll an approved device when legitimate. Assess data exposure before closing the alert.
