Matrix Array Arena is a zero-trust security gate for AI-generated and untrusted code. Paste any payload and it is scanned by a deterministic, deny-by-default 9-layer gate that returns an instant APPROVED or BLOCKED verdict with line-level violations — covering injection, exfiltration, dynamic execution, secrets, obfuscation and more.
Blocked code can be repaired by a tri-AI council (Claude, GPT and Gemini) whose output is re-scanned before you decide. Nothing ever executes without explicit human approval, and every decision is recorded in a tamper-evident audit trail.
The public Threat Wall and leaderboard rank the nastiest blocked payloads, AI agents can request scans through an MCP endpoint with a human approval queue, and the free Local Sentinel runs the same gate fully offline on your own machine.
