Open-source AI agent firewall for MCP security: agent egress control, DLP, SSRF, and prompt injection defense.
Open Source Reliability Harness: Make your agents follow rules. One line of code to enforce, trace, and improve.
AI Security Platform: Defense (61 Rust engines + Micro-Model Swarm) + Offense (39K+ payloads)
AI Agent Security Middleware — 8-layer defense, DLP data flow, prompt injection detection, zero dependencies. SDK + MCP server for Claude Code, Cursor, LangChain, Hermes Agent & more.
Prompt-injection guardrail for LLM applications. Compact model that outperforms larger open-source guards. No regex, no signatures. Demo: anton.securelayer7.net
AI Firewall and guardrails for LLM-based Elixir applications
OpenClaw Execution Firewall - Seccomp-locked AI agent sandbox with policy-enforced command governance, WhatsApp/Telegram integration, and Python isolation. Deploy on Oracle Cloud Free Tier.
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.
Geometric AI governance and evaluation framework with a 14-layer security pipeline, semantic projection, and reproducible benchmark lanes.
korveo — the open-source firewall & flight recorder for AI agents. Local-first, Apache-2.0.
The security layer for AI prompts. A unified monorepo for detecting and neutralizing adversarial Unicode, invisible character poisoning, and homoglyph attacks in LLM workflows. Includes the GhostBuster engine, VS Code extension, and CLI.
TrustLayer is an API-first security control plane for LLM apps and AI agents. It protects production systems from prompt injection, tool hijacking, and behavioral drift, and provides incident lockdown when attacks are detected. Built for fast integration, low latency, and real production use.
ZeroShield AI Mesh Firewall is a centralized AI security gateway for governing LLM and RAG traffic with inline prompt injection defense, vector database isolation, multi model routing control, and compliance grade observability.
Deterministic validation firewall that verifies AI-generated proposals against ground-truth state using immutable rules. Zero dependencies. Patent pending.
