datafog

Offline PII firewall for AI agents and LLM apps: fast local detection and redaction, Claude Code hook, LiteLLM guardrail. Zero network calls, one dependency.

ethyca-fides

The Privacy Engineering & Compliance Framework

diffprivlib

Diffprivlib: The IBM Differential Privacy Library

presidio

An open-source framework for detecting, redacting, masking, and anonymizing sensitive data (PII) across text, images, and structured data. Supports NLP, pattern matching, and customizable pipelines.

pseudonymize

Typed, dependency-free Python toolkit for local-first PII pseudonymization, deterministic aliases, redaction, safe reports, and extensible detection backends.

piighost

Reversible PII masking for LLM agents: piighost replaces personal data with placeholders before the model sees it, then restores the real values in replies and tool calls. LangChain, Pydantic AI, LlamaIndex and Claude Code integrations, plus an OpenAI/Anthropic-compatible proxy.

agent-paranoid-android

Reproducible synthetic test data for CSV and database workflows.

shim

Local traffic visibility and privacy controls for coding agents. See what Claude Code, Codex and Copilot actually send to the model, and mask secrets and personal data before they leave your machine.

tarja

Detect and mask Brazilian personal identifiers (CPF, CNPJ, CNS, CNJ, título, CNH) in Portuguese text, with check-digit validation. For LGPD work, DLP pipelines, and stripping PII before text reaches an LLM or a RAG index. Apache 2.0, no dependencies.

pycanon

pyCANON is a Python library and CLI to assess the values of the parameters associated with the most common privacy-preserving techniques.

acro
