Why an MVP PII Catalog Matters
An MVP PII catalog is your first, lean, production-ready map of where Personally Identifiable Information lives in your systems. It identifies the fields, files, and streams that contain user data—names, emails, addresses, IDs, payment info—and links them to the applications, APIs, and databases that store or process them.
Building one fast matters more than building it perfect. A complete enterprise PII catalog can take months. An MVP PII catalog can be up in hours. It gives you immediate visibility to reduce risk, comply with regulations, and enforce access controls. Once it exists, you can iterate, deepen the classifications, and automate scans.
The core steps:
- Inventory every data store connected to production.
- Identify tables, columns, and objects containing PII.
- Classify PII by sensitivity level and usage context.
- Map data flow between systems.
- Store the catalog in a versioned, queryable format.
Tools and automation can help detect PII across structured and unstructured sources. But engineering still needs to validate and maintain accuracy. An MVP PII catalog should integrate with your CI/CD pipeline, security tests, and incident response plan. It should also be easy for compliance, privacy, and security teams to query without roadblocks.
This is not a one-off exercise. It is the spine of your data governance program. Without it, you are guessing at your exposure. With it, you know exactly where your risks are—and can prove it to auditors, regulators, and your own leadership.
