How do I start if I have zero PII inventory today?

Automate first. Run a lightweight DLP scan (Macie, GCP DLP, or open-source) across raw zones and push tags into a catalog (DataHub/Atlas). Make classification a required check in your CI — no tag, no deploy. Within two weeks you’ll have 90% coverage and can backfill the long tail.

Is dynamic masking enough without tokenization?

No. Masking protects at query time; leaks upstream (CSV exports, debug logs) bypass it. Tokenize high-risk fields at ingress with Vault Transit or a dedicated service, store tokens in analytics, and only detokenize with break-glass access and audit.

We’re on Databricks. Can we still do ABAC and masking?

Yes. Use Unity Catalog for centralized governance, table ACLs, and dynamic views for masking. Pair with Immuta/Privacera for ABAC and purpose binding. OpenLineage emits from Spark/Delta for lineage.

What KPIs prove this is working?

Track: privacy incident rate and MTTR, SLO adherence for freshness/completeness, time-to-approve data access, number of policy violations caught in CI vs prod, audit duration. Show trend lines to leadership quarterly.

Won’t all this slow down analysts?

Counterintuitively, it speeds them up. Standardized access via ABAC and JIT roles replaces weeks of ticket ping-pong. Clean, tested datasets reduce rework. The guardrails remove fear, so approvals happen faster.

How does GitPlumbers engage on this?

We run a 2–3 week assessment (inventory, risk, quick wins), implement policy-as-code and masking on a pilot domain, wire in tests/lineage, and hand you dashboards with SLOs. Then we scale the blueprint across domains with your team, not to you.
