Audit calendar invites for compliance violations
Scan event invites across all user calendars to flag external guests, missing conferencing, or other compliance issues before incidents occur.
| Who it is for | IT security, compliance, and governance teams in regulated environments. |
|---|---|
| APIs | Calendar API, Admin SDK |
| Typical scopes | calendar.readonly, admin.directory.user.readonly |
The problem
Calendar events often include sensitive details or unauthorised guests, but these risks are invisible without systematic review. Manual sampling misses most violations and is not workable at scale.
How it works
- Enumerate active users via the Admin SDK.
- Impersonate each user with calendar.readonly and page through their upcoming and recent events.
- Parse event details for policy violations, such as unauthorised external guests, missing conferencing links, or sensitive keywords.
- Log flagged events and notify the compliance team for review.
What changes
Compliance teams gain a current, actionable list of risky calendar events, reducing the chance of policy breaches going undetected.

Questions people ask
Can this check historical events as well as upcoming ones?
Yes, but the Calendar API paginates results and only expands recurrences within a set date range. For complete coverage, iterate over both past and future windows.
Does this notify users or just compliance teams?
By default, just compliance teams. You can extend it to notify users, but use caution to avoid accidental data leakage about invitees.
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.
