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.

loggingredactor

Logging Redactor is a Python library designed to redact sensitive data in logs based on regex patterns and / or dictionary keys.

privaite

Drop-in self-hosted LLM proxy that reversibly redacts PII before OpenAI, ChatGPT and Ollama calls, including inside tool-call arguments and multimodal content. OpenAI-compatible, zero telemetry.

promptsanitizer

Secrets firewall for AI pipelines — redact credentials and PII before they reach (or leave) LLMs.

admina-core

The open framework for governed AI development: EU AI Act compliance, PII redaction, MCP proxy, prompt-injection firewall. Python + Rust, Apache 2.0

gavio

The open standard AI gateway — PII protection, audit, reliability & cost control as composable interceptors. Same API in Python, Java & JavaScript.

admina-framework

The open framework for governed AI development: EU AI Act compliance, PII redaction, MCP proxy, prompt-injection firewall. Python + Rust, Apache 2.0

akios

Secure runtime for multi-agent AI. Kernel sandboxing (seccomp-bpf), real-time PII redaction, Merkle audit trails.

pii-shield-wasi

Zero-code K8s sidecar for log sanitization. Detects secrets via Entropy Analysis, preserves JSON integrity, and redacts PII deterministically. 🛡️

sandcastle-ai

Describe what you want. Go home. Sandcastle ships it. 6 AI providers, EU data residency, smart failover, cost intelligence, 20 step types, 236 templates. European-built, open source. pip install sandcastle-ai

hexlock

Format-preserving PII anonymization for LLM pipelines

enforcecore

Lightweight runtime enforcement for agentic AI. PII masking, policy checks, and Merkle audit trails as a decorator.

ai-audit-trail

Cryptographically verifiable audit trail for AI systems — Ed25519 signed, hash-chained Decision Receipts with ISO 42001 / NIST AI RMF compliance. No blockchain, no SaaS.

gradio-image-annotation-redaction

A Gradio component that can be used to annotate images with bounding boxes, focused on redaction tasks. Forked from the original by edgarGarcia for use with the Document Redaction app/repo (see link below)

dbveil

A local read-only, PII-redacting proxy that lets AI agents query your database safely.

surrogateshield

A privacy-first guardrail for LLMs and RAG pipelines. SurrogateShield detects, redacts, and reconstructs sensitive PII data on the fly while defending against adversarial attacks.

llm-safe-pl

DEPRECATED — use pii-veil + pii-core instead. Reversible PII anonymization for Polish documents.

kvfleet

Production-grade, KV-cache-aware intelligent routing for self-hosted and hybrid LLM fleets.

pii-redact

Detect and redact PII locally with SOTA performance

guarded-rag

Guarded RAG: grounded answers, refuse-when-unsupported, PII redaction + eval harness. Stdlib core, bring-your-own model.

mcp-doorman

Secure-by-default FastAPI->MCP bridge. Deny-by-default exposure, scope->tool auth that fails closed (even on STDIO), built-in rate limiting, PII redaction at the source, and a structured audit log — in-process, no gateway.

aisafeguard

Open-source LLM safety guardrails: prompt injection protection, PII redaction, toxicity filtering, and OpenAI-compatible AI proxy
