pg_redact is a Postgres extension that uses content-aware PII detection to redact personal information in free-text fields. It combines regex pattern matching to identify candidate snippets with Jev, TypeSafe's classification model, to determine what constitutes PII in context, then applies role-based masking rules via SQL functions.
ScrubVault is a lightweight, zero-dependency Python privacy proxy that masks personally identifiable information (emails, IBANs, credit cards, tax IDs) in prompts before sending them to cloud LLMs like ChatGPT and Claude, then restores original values in responses. It operates entirely in-memory, includes MCP server support, and provides CLI tools for auditing GDPR compliance risk and scrubbing datasets.
