Centralised audit of third-party app access across Workspace

Enumerate OAuth grants and connected apps for every user to surface risky or unauthorised third-party access in one place.

The problem

Third-party apps often accumulate over time, many with excessive permissions or from unknown vendors. Native admin panels only show a live snapshot, and per-user reviews are unscalable, so dangerous access can persist unnoticed.

How it works

  1. Enumerate all users in the domain using the Admin SDK.
  2. For each user, impersonate and query their OAuth grants via the user security endpoint.
  3. Aggregate all discovered app authorisations, including scopes and app metadata, into a central data store.
  4. Flag apps with high-risk scopes or from unapproved publishers for review.

What changes

You get a complete, reviewable record of every app that users have authorised, with enough detail to drive revocation or policy changes.

The trap in this one. The Admin SDK's user security endpoint caches results for several minutes and does not reflect immediate grant or revoke actions. If you schedule audits immediately after suspected changes, your export will be stale and may miss or double-count authorisations. Always document the data timestamp and avoid triggering incident response based solely on freshly revoked app data.

Questions people ask

Can this catch apps installed via the Marketplace?

Yes, if they are authorised with OAuth scopes on a per-user basis. However, domain-installed apps with implicit trust may not appear as user grants.

How often should the audit run?

Daily is typical, but the underlying API cache means more frequent runs provide little extra benefit and may increase quota usage.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
