See who's inside — and what they can reach.
Outsight scans your Microsoft 365 tenant and surfaces every external user, pending invitation, and stale guest. Audit-ready in minutes. Read-only, no agent installs, no data leaves your instance.

What you'll see
- Every guest user — sorted by staleness and last sign-in
- Pending B2B invitations that never got redeemed
- Guests who have never signed in (top cleanup candidates)
- Export to PDF for handing to auditors
Why it works
Outsight requests read-only Graph scopes
(
User.Read.All, Directory.Read.All,
AuditLog.Read.All, Sites.Read.All).
A global admin grants consent once. No writes, ever.
