Introducing Sensitive Data Classifier

Released on: April 2026

Atatus Sensitive Data Classifier (SDC) delivers real-time discovery, classification, and redaction of PII, credentials, and regulated data across logs, APM traces, RUM events, and cloud storage at petabyte scale with under 5ms ingestion scan latency.

With 30+ production-ready detection rules and support for custom regex patterns, security and platform teams can prevent sensitive data exposure before it reaches storage, third-party integrations, or downstream systems without building custom pipelines or deploying additional infrastructure.

Introducing Sensitive Data Classifier

Key Features of Sensitive Data Classifier in Atatus:

  • Real-Time Scanning at Ingestion: Scan and transform sensitive data in-flight before it is written to storage. Emails, API tokens, card numbers, passport IDs, and other sensitive values can be redacted, hashed, or masked instantly with zero reprocessing overhead.
  • 30+ Validated Detection Rules Library: Detect credit cards, SSNs, IBANs, API keys, OAuth tokens, AWS/GCP/Azure credentials, UK National Insurance Numbers, US passport numbers, Canadian SINs, JWTs, Bearer tokens, and more using continuously maintained detection rules.
  • Custom Regex Rules: Create custom detection patterns using standard PCRE regex. Configure confidence thresholds, character preservation settings, and custom tagging schemas for organization-specific sensitive data formats.
  • Multiple Redaction Strategies: Apply full redaction, SHA-256 hashing, partial masking with configurable visibility rules, or fixed-string replacements based on rule type and scanning group requirements.
  • Tag-Based Scanning Groups: Target specific services, environments, or telemetry sources using tag-based filters. Apply rules selectively across logs, APM spans, RUM events, and pipeline streams with granular control.
  • Full-Stack Data Stream Coverage: Scan telemetry across log agents, Lambda functions, syslog streams, APM span tags, HTTP payloads, SQL queries, browser RUM events, and mobile monitoring pipelines without deploying sidecars or extra agents.
