Protect sensitive data in LLM observability pipelines with automated PII detection and redaction.

| Detection engine | Presidio (enterprise), regex (simple), LLM Guard (LLM pipelines) | | Masking strategy | Replace with type tokens [REDACTEDEMAIL] for debuggability | | Performance | Use async/batch processing for high-throughput | | Langfuse integration | Use mask= callback at client initialization |

| Reversibility | Use LLM Guard Vault for deanonymization when needed |

PII detection and masking for LLM observability. Use when logging prompts/responses, tracing with Langfuse, or protecting sensitive data in production LLM pipelines. Source: yonatangross/orchestkit.
