It wasn’t supposed to be there. But it was—and no one knew for how long. That’s how most PII leaks happen: quietly, invisibly, until they become a security incident.
The Guardrails PII Catalog exists to stop that moment from ever happening.
A PII catalog is the single, reliable source for identifying, classifying, and tracking sensitive data—names, emails, phone numbers, addresses, credentials—across every part of your system. When paired with automated guardrails, it becomes your early warning system. It tells you what’s flowing where, and stops it before a human has to stumble on it by accident.
The strongest catalogs are continuous, not static. They scan pipelines, storage, event streams, and APIs. They work in CI/CD, they listen in real time, and they adapt as new data shapes appear. This is more than regexes and keyword checks—it’s detection powered by multiple layers: pattern recognition, machine learning classifiers, and tight integration points with your existing data flows.
