Detect policy violations in Google Docs at scale

A delegated service account scans all Docs in the domain for sensitive content or compliance breaches, flagging violations for review without reading private material unnecessarily.

The problem

Sensitive information and regulated data end up in documents, often outside the intended controls. Manual review is impossible at scale, and breaches can go unnoticed until a data loss event or audit failure.

How it works

  1. Enumerate all user-owned Docs using the Drive API with domain-wide delegation.
  2. For each document, fetch metadata and permissions to exclude irrelevant or externally owned files.
  3. Download or read the document body using the Docs API only if it matches risk patterns (e.g., keyword, sharing status).
  4. Run automated scans for policy violations and log flagged documents for human review.
  5. Notify the responsible parties or lock down sharing as required.

What changes

Compliance teams gain visibility into risky documents before they leave the domain or trigger incidents, reducing exposure windows and audit gaps.

The trap in this one. Drive API file listings are eventually consistent. A document created or shared moments before the scan may not appear in the results, leading to blind spots in detection. Relying on a single crawl for coverage means recent violations may be missed entirely until the next pass—this is especially problematic in domains with high document churn.

Questions people ask

Does this process read every document in full?

Not always. You can use metadata and sharing settings to target only likely violations, reducing unnecessary access and false positives.

How often should scans run to stay effective?

Frequency depends on document volume and risk tolerance, but due to API consistency delays, running more frequently does not guarantee immediate coverage.

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.
