The data was leaking before anyone noticed. But the queries kept running, the dashboards kept updating, and the engineers thought everything was fine. It wasn’t. Sensitive information was moving through streams unprotected, exposed in logs, caches, and analytics pipelines. That’s when Radius Streaming Data Masking changes the game.
Radius Streaming Data Masking protects sensitive fields in motion. It modifies data in real time, at the stream layer, before it ever lands in storage or downstream systems. No waiting for batch processes. No risk window. No unmasked payloads slipping through.
Unlike static masking, which works only on stored data, Radius Streaming Data Masking operates inline with high-throughput event streams like Kafka, Pulsar, or Kinesis. It intercepts messages, applies masking policies instantly, and forwards them without breaking schemas or slowing the pipeline. This means developers keep the same APIs and consumers, but security teams gain immediate control over every sensitive field.
Effective masking depends on precision. Radius uses rule-based matching, pattern recognition, and field mapping to find and mask values like PII, account numbers, API keys, or anything defined in its masking ruleset. You choose between irreversible masking for fields that never need to be recovered, or reversible tokenization for cases where authorized systems must restore the original.
Performance matters. Radius Streaming Data Masking processes terabytes per hour with sub-millisecond latency per record. It scales horizontally, handles burst traffic, and integrates without forcing teams to rebuild pipelines. It supports both centralized policy management for compliance audits and local policy overrides for development flexibility.
