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

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

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.

Lightweight Python SDK for PII detection, redaction, and LLM guardrails, with fast regex defaults and optional NLP/OCR/Spark extras.

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.

Self-hosted AI security proxy. Redact PII, block prompt injection, route to any LLM provider. OpenAI-compatible.

The open-source security layer for AI agents. Deterministic guardrails, PII redaction, and EU AI Act compliance in one line of code.

Coroutine-driven Android file logger with pluggable sinks (file, logcat, HTTP), MDC, JSON output, lazy lambda API, PII redaction, and a crash handler.

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

Open-source AI platform for personalized conversations — embeddable chat widget, pluggable LLM engines, PII redaction, voice I/O, and admin-driven intent & preset personalization.

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.

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

Self-hosted LLM security proxy. PII redaction, prompt injection defense, KVKK/GDPR/PCI-DSS compliance. Sub-millisecond latency.

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.

Six in-process middlewares for OpenClaw: HITL approvals, prompt-injection guardrails, PII redaction, tool-call budgets, context compaction, and complexity-aware model routing. Zero telemetry, all state local.

Comparison case study between Gliner V2 vs OpenAI Privacy filter model for PII Redaction

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