AWS open-sources prompt-configured PII detector
AWS released pii-detector, an open-source, model-agnostic system that finds PII in messy multilingual text using configurable prompts and structured JSON output. It supports Amazon Bedrock or self-hosted models and was benchmarked across 49,365 records and 222,114 annotated spans.
// ANALYSIS
The real innovation is configurability: teams can add domain-specific identifiers by editing prompts instead of retraining a token classifier. The tradeoff is that LLM-based detection adds inference cost, latency, and privacy considerations.
- –Supports 15 PII categories and was evaluated across eight languages
- –Uses a swappable Inferencer interface for Bedrock or self-hosted open models, including air-gapped deployments
- –AWS reports 83.1% Core F1 for Mistral Large 3; Claude Sonnet 4.6 reached 84.2% in the same benchmark
- –Post-processing recovers character offsets and normalizes near-miss labels emitted by LLMs
- –Best suited as a flexible detection layer alongside deterministic rules and human review, not as a complete DLP replacement
