Use Case
Mask PII before logs are routed
Protect sensitive fields before indexing or archival.
Problem
Sensitive values can leak through debug logs and request payload logging.
Fixing data exposure after ingestion is slow and operationally risky.
Example
Token-like fields and email addresses appear in raw request and error events.
Security teams require centralized redaction policy rather than manual service-by-service patches.
Solution (LogTrim)
Apply deterministic masking for known sensitive keys and data patterns.
Sanitize logs in the pre-ingestion path so Datadog and S3 receive redacted payloads.
Audit masking rules as part of release and incident review cycles.
