It automatically enforces redactions, access control, and audit logging, so you can safely connect LLMs or analytics systems to real data without leaking sensitive information.

Recent update

Just released Global Regex Redactions — pattern-based rules (like emails, SSNs, or credit cards) that apply across all tables automatically.

Other improvements: • Expanded audit logging (create, update, delete events) • Cleaner, more modern redaction management UI • Docker setup reliability • Foundation for role-based access control

⸻

How it works • Runs locally or via Docker Compose • Connects to PostgreSQL or MySQL • Provides a web UI for managing connections, regex rules, and audit logs • Works with AI query interfaces (e.g. natural language → SQL)

⸻

Example use cases • Safely connect a local or hosted LLM to your production database • Build internal chatbots or dashboards without exposing PII • Enforce consistent privacy rules across teams or tools

⸻

It’s early-stage but functional, and I’d love feedback on what privacy or compliance features you’d want next. Repo: https://github.com/tyoung1996/guardrail-layer
