Every autonomous agent has to be approved before it acts, governed while it acts, and audited after it acts. Quad-AI is the only production-deployed system that covers all three moments at runtime — with native adapters for the agent frameworks every Tier-1 buyer is already using.
Single-vendor guardrails only see one moment. The Quad-AI agentic trust layer governs the whole action lifecycle, with cryptographic chain of custody binding every verdict to the action that follows.
The agent's tool call is parsed by net-new action-payload introspection logic. Verb, target, parameters, calling-agent scope, and risk-relevant fields are extracted before execution.
Claude Opus 4.5, Gemini 2.5, GPT-5.1, and Sonar Pro evaluate the action concurrently. The adversarial verifier mesh kicks in on high-risk actions. Greenlight / block / escalate with a dissent register.
Every verdict produces a SHA-256 audit bundle: proposed action, verdict, recommended modification, escalation route, dissent register, and an append-only downstream-action hash chain binding the bundle to the action eventually taken.
Each scenario below is a real agent tool-call payload. Click one, then run a verdict. The pre-action gate, the four-provider consensus, and the audit bundle are all real and live — not staged. Latency varies by risk tier.
Multi-tenant isolation: Switch the tenant dropdown below to run as a different buyer. Every audit bundle is keyed to its owning tenant. Use the Run Cross-Tenant Isolation Probe button after any verdict to prove that a buyer in tenant_b cannot read tenant_a's audit bundle — the owner request returns 200, the intruder request returns 404 (not 403 — no existence leak).
Public sandbox · do not submit real PII, customer data, or production credentials. All scenarios above use synthetic data.
One integration. Three of the most-used agent frameworks in production. The adapters translate framework-native payloads into the pre-action gate without custom wiring.
Native adapter for MCP tool-call envelopes. Any MCP-compliant agent — across the entire Anthropic ecosystem — can call Quad-AI as a pre-action gate with no custom wiring.
Pre-action gate fires between the assistant's tool-call decision and the actual function execution. Drop-in for any Assistants-API-based agent in production.
Higher-throughput adapter for action streams. Risk-tier-based sampling: low-risk actions (screenshot, mouse-move) clear on the fast path; high-risk actions get the full pipeline.
Public sandbox note. Audit bundles generated on this page are SHA-256 hash-verified and held in ephemeral in-memory sandbox storage (non-durable). Production deployments use durable, immutable audit storage with tenant-administered chain-of-custody binding. Per-tenant policy and downstream-action binding endpoints are admin-gated and available under private integration agreement.
