Pii Catalog in Zscaler

The alert fired at 03:17. A flood of personally identifiable information was moving through a Zscaler tunnel. It wasn’t supposed to.

Pii Catalog in Zscaler changes this. It’s the structured index of all detected PII—names, emails, credit card numbers, national IDs—flowing through your network. With it, you go beyond alerts. You see exactly what was captured, where it traveled, and why it crossed a policy line.

Zscaler’s Pii Catalog works by aggregating data from inline inspection engines. Every transaction is scanned in real time for PII fingerprints. Matches are normalized, categorized, and stored in a searchable catalog. Engineers use this to identify patterns in leaks. Managers use it to enforce compliance. Security teams use it to shut down unauthorized flows before they become incidents.

Integration makes it stronger. The Pii Catalog ties into DLP policies, CASB controls, and zero trust enforcement. When a record appears, you can trace it back to its source IP, application identity, and user session in seconds. That speed is the difference between a contained breach and a public nightmare.

Common use cases:

• Audit outbound email for hidden PII.
• Track uploads to cloud storage against compliance rules.
• Map PII exposure in SaaS apps over time.
• Build reports for regulatory audits without manual searching.

Best practices: enable full-content inspection on Zscaler traffic, configure custom regex for region-specific PII formats, and sync catalog entries with your SIEM for correlation. Maintain a clear retention strategy so the catalog holds only necessary records, reducing risk of secondary exposure.

The Pii Catalog is not optional if you move critical data through Zscaler. It is visibility, control, and proof—everything you need to meet compliance and shut down leaks fast.
