Microsoft Presidio
Open-source PII detection and anonymization framework from Microsoft. Identifies, redacts, masks, and replaces sensitive entities (names, SSNs, credit cards, emails, etc.) across text, images, and structured data using NLP, regex, and rule-based recognizers in multiple languages. Integrates as a Python library, Docker container, or Kubernetes deployment. Fully free and self-hosted.
Viable option — review the tradeoffs
You need to detect and anonymize PII in text, images, or structured data across your agent pipelines without vendor lock-in or costs.
Solid out-of-box accuracy on common entities like names/emails/SSNs; tune for custom needs but expect some misses on edge cases—always validate outputs.
Your agents process unstructured logs, docs, or images with hidden PII that risks leaks in production.
Fast on regex patterns, slower with ML on large volumes; highly extensible but requires tuning confidence thresholds to cut false positives.
No 100% Detection Guarantee
Automated mechanisms miss some PII; docs explicitly warn to pair with other protections for compliance.
ML Resource Overhead
Recognizer models like spaCy eat CPU/GPU on scale; use batching, queues, or lighter regex-only mode to avoid slowdowns.
Presidio wins on ML/context accuracy and image support; Scrubadub is lighter for pure regex needs.
Need advanced NLP, images, or heavy customization in agents.
Want dead-simple, low-resource regex scrubbing without ML setup.

What It Actually Does
Microsoft Presidio finds sensitive personal info like names, credit card numbers, and emails in text, images, or tables, then hides or replaces it to protect privacy.[1][2]
