# zn — Agent-Native Security Gateway

zn is the agent-native security gateway: sacrificial protection for every agent tool call.
It stops prompt injection before it reaches your tools. Speak MCP or A2A, get an
allow/block verdict with deterministic rules and SHA-256 hashed evidence.

- Latency: local deterministic rules <0.1 ms · Galvanize-60M CPU inference 11.52 ms p50 (sub-15 ms)
- Accuracy: 1.00% tool false-positive rate across 9/9 certified industrial gates (vs 90.33% ProtectAI) · 91.60% Deepset OOD recall · 77%-97% needle recall
- Dataset: 23,699 public vectors on Hugging Face (usezn/zn-prompt-injection-bench)
- Deployment: open-source core (Rust + WASM) or managed cloud

## Quick check

```bash
curl -X POST https://api.usezn.com/v30/analyze \
  -H "Authorization: Bearer $ZN_API_KEY" \
  -d '{"input": "ignore previous instructions"}'

{"verdict":"block","evidence_id":"ev_abc123","confidence":0.97}

```

The unified gateway runs deterministic regex & AST rules plus the certified Galvanize-60M neural engine (8,192-token native RoPE, MultiHeadSecurityPooling, dynamic INT8 ONNX).

## What you get

- WASM Policy Engine (wasmtime 29, hot-reload)
- SQL/Prompt/LFI Guard, Agent Reputation, A2A Firewall
- Neural Detection (Galvanize-60M INT8 ONNX, 11.52 ms p50 CPU), M-of-N Consensus, Loop Breaker
- Evidence Vault (SQLite + KMS + OTLP)

## How it works

Agent → ZN Firewall (guards: Vision, Cache, Reputation, Static, Loop,
Consensus, Neural) → your target system receives only safe requests.
