This control plane turns Entra guest-access snapshots into one identity-governance surface: invitation sprawl, missing access reviews, stale sponsors, inactive guests, cross-tenant trust gaps, and the remediation packets needed before external collaboration drifts.
| Guest lane | Owner | Status | Related findings | Focus | Next action |
|---|---|---|---|---|---|
| Invitation governance lane Direct guest invitations are still bypassing the reviewed intake path. |
Identity Governance | red | 1 | Sponsor-bound invitations, intake control, and least-privilege B2B access | Route new guest invites back through the sponsor-approved access path. |
| Access review lane One supplier-facing guest group is missing its active review and stale users still remain. |
Platform Operations | red | 3 | Review cadence, inactive guest cleanup, and renewal decisions | Reopen the quarterly review and prune stale guest members before renewal. |
| Cross-tenant trust lane Partner trust is recoverable, but one inbound setting is still wider than the approved baseline. |
Security Operations | yellow | 1 | Partner trust settings, inbound claims, and collaboration posture | Constrain inbound trust to the reviewed collaboration scope. |
| Audit continuity lane Audit continuity exists, but sponsor and sign-in evidence are still partially stale. |
Identity Governance | yellow | 6 | Guest sign-in evidence, sponsor attribution, and telemetry completeness | Restore guest audit exports and close sponsor attribution gaps. |
