Personal Identifiable Information (PII) spread across systems without a map is a liability waiting to explode. A PII catalog fixes this. It is the single source of truth for every data field that can identify a person—names, emails, IDs, addresses, biometric data, geolocation, financial records. Without it, regulatory alignment is guesswork.
Regulations like GDPR, CCPA, HIPAA set strict rules for where PII lives, how it’s used, and who can touch it. They demand proof—proof you know your data, track it, and protect it. A complete PII catalog gives that proof. It links every PII element to its storage location, usage path, and retention policy. It makes compliance measurable instead of manual and chaotic.
Regulatory alignment means matching your data handling to the letter of each law. It’s not just classification—it’s context. You map PII fields to relevant regulations, flag risky flows, and enforce access controls. The PII catalog becomes the backbone for automated audits, breach investigation, and policy enforcement.
