Masking PII and PCI in motion, on stage with Blip

At Current 2026, Erick Da Silva (Datatchê) and Leo Bombonato (Blip) show how to detect and mask sensitive data inside the stream, before it reaches any downstream system, with Kafka and Flink on Confluent Cloud.

Breakout session

Masking PII/PCI in Motion: Real-Time Data-Loss Prevention with Kafka and Flink on Confluent Cloud

Most data-loss prevention happens after the fact: batch scans, nightly jobs, audits that find the leak days later. We shifted DLP left, into the stream itself, so PII and PCI are detected and masked before a record lands anywhere else, a pattern we took from the lab to a real client engagement.

What you will take away

  • A concrete pattern for in-stream redaction and tokenization with Flink SQL and a Java UDF calling an external DLP API.
  • How to balance automated masking against human review to control false positives.
  • How to budget the latency and cost of an external call per event, and keep it observable.
  • A fail-open design so a DLP outage never stops the stream, provisioned as code with Terraform.
