PII Catalog Security Review is how you make sure that never happens. It’s not optional. It’s the baseline for controlling Personal Identifiable Information across every service, database, and workflow. When PII appears in new tables, new APIs, or logs, you need to know—fast.
A strong PII catalog is more than a list of data assets. It is a living map of where sensitive fields exist, how they move, and who can touch them. Security review means you verify this map is accurate, complete, and enforced. Without that process, you run on guesswork. Guesswork is attack surface.
The review should start with detection. Scan all structured and unstructured data stores for names, emails, phone numbers, government IDs, payment details. Use automated discovery tools that integrate with your pipelines. Schedule scans often enough to catch changes before they go live.
Classification comes next. Tag data by sensitivity. High‑risk PII should have encryption at rest and in transit, strict role‑based access controls, and detailed audit logs. Medium‑ or low‑risk PII may have different retention rules, but must still meet compliance standards.
