The Open Source Firewall for LLMs. A self-hosted gateway to secure and control AI applications with powerful guardrails.

Detect and redact PII locally with SOTA performance

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

Python SDK for PII detection and redaction in text and images, combining regex + NLP pipelines for production privacy workflows.

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

Guardrail capabilities for Pydantic AI — cost tracking, prompt injection detection, PII filtering, secret redaction, tool permissions, and async guardrails. Built on pydantic-ai's native capabilities API.

Open-source security gateway for LLM APIs — prompt injection detection, PII redaction, dangerous response sanitization, and audit logging. OpenAI/Claude compatible, MCP & Agent SKILL support. Drop-in proxy for AI coding agents (Cursor, Claude Code, Codex).

Real-time behavioral intelligence for call centers. Transcribes support calls, redacts PII, extracts emotional tone, classifies issues, and delivers insight-rich dashboards — powered by GPT-3.5 (cheap tokens), Whisper, DuckDB, and a polished React+TypeScript frontend. No Azure. No Power BI. No vendor lock-in. Just full-stack AI that runs local.

Ultra-low-latency LLM gateway with microsecond caching, dynamic routing, budgets, analytics, and forecasting.

Headless, OpenAI-compatible AI gateway in Go. Multi-tenant auth, tracing, cost tracking, rate limits, and optional PII redaction. Single binary, self-hosted, audit-ready by design.

🛠️ Claude Code / OpenClaw Skill — Turn support tickets, logs, screenshots into sanitized engineering issue packs. 17 PII redaction patterns, log parsing, stack trace extraction (Python/Java/JS/Go), error code classification, timeline. 客服工单脱敏 | 隐私数据脱敏 | 日志解析 | 堆栈提取 | 错误码分类 | 中英双语Skill | 支持转研发问题包生成器

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

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

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

Semantic Privacy Guard: A Java middleware that intercepts text, identifies PII using a three-layer hybrid pipeline (Regex + Naive Bayes ML + Apache OpenNLP NER), and redacts it before it reaches an LLM or leaves the corporate network — with stream-based processing for memory-efficient handling of large files and log streams.

Masker - PII Redaction API for LLMs. Remove personal data before sending to ChatGPT, Claude, etc.

This repository contains a solution for Multimodal PII (Personally Identifiable Information) Redaction using Amazon Bedrock. The solution provides a workflow for detecting and redacting PII from emails and attachments using various AWS services including Amazon Bedrock Data Automation, Amazon Bedrock Guardrails, Lambda, S3, DynamoDB, and more.

The open-source security firewall for AI Agents. Prevent destructive SQL, redact PII, and enforce strict governance policies for AWS Strands and LangChain.

A blazing-fast, zero-dependency PII scrubbing engine for LLMs. Multi-core parallel processing, synthetic data generation, and compliance auditing out of the box.
