Enforce document sharing policy at the point of creation

Automatically apply sharing settings to new Drive files, so nothing leaves the domain without review.

The problem

Users often share documents externally before IT can intervene, risking data leakage. Manual reviews are slow and miss files, especially when folder inheritance is unclear.

How it works

  1. Monitor Drive activity for new file creation events.
  2. Impersonate a compliance user to adjust permissions immediately after file creation.
  3. Set or restrict sharing as required by policy (e.g., remove external access, enforce domain-only sharing).
  4. Log changes for audit and compliance reporting.

What changes

Files are locked down to the right audience from the start, and external shares require explicit exception handling.

The trap in this one. Drive API's permission changes can silently fail if the file is owned by a user in a different organisational unit with conflicting sharing settings. Worse, permission propagation is not instant: if you update permissions immediately after creation, the file may not yet be fully indexed, and the API returns 404 or applies the change only partially. Always retry with exponential backoff and verify the final state, or you will miss files under heavy load.

Questions people ask

Why not set sharing on the parent folder instead?

Folder permission inheritance is not always respected if users override sharing on the file. Files created in shared drives also have different rules.

How do I know if a permission change succeeded?

The Drive API returns the updated permission object. Always fetch permissions again after a delay to confirm the intended state, especially after bulk operations.
