PII Catalog for Streaming Data Masking
The stream never stops, and neither does the flow of personal data. Every packet, every event, carries the risk of exposing something that was never meant to be public. Without control, PII leaks downstream into logs, analytics, and caches — impossible to recall once it escapes.
A PII catalog for streaming data masking is how you take control at the source. It maps every field, column, and event attribute that contains Personally Identifiable Information in real time. It gives you a living inventory of sensitive data flowing through your pipelines. This catalog is not static; it updates as schemas change and new event types appear.
Streaming data masking applies transformation rules inline. Names, emails, phone numbers, IPs — detected and masked before they reach unauthorized systems. Instead of post-processing or scheduled batch jobs, masking happens on the wire. This reduces risk windows to zero.
The core workflow is simple but precise:
- Discover PII automatically from structured and semi-structured messages.
- Register it in the PII catalog with exact data lineage.
- Apply field-level or tokenized masking transformations at ingestion speed.
By connecting the catalog and the masker, you achieve consistent governance. You avoid mismatched regexes scattered across services. You keep compliance auditors satisfied with a single source of truth for where PII lives and how it’s protected.
PII catalog streaming data masking scales with event volume because it is built for low-latency pipelines like Kafka, Kinesis, or Pulsar. It works without needing to rewrite producer code. New topics or streams are automatically scanned, classified, and masked according to policy. This means faster onboarding of data sources and immediate enforcement of privacy rules.
Strong security is not just about encryption in transit or at rest. It is also about ensuring sensitive values never appear in plaintext in systems that do not need them. Combining a PII catalog with streaming data masking gives you that control without slowing the flow.
