The Behavioral Firewall for AI Agents.

Prevent · Prove · Rate. Trust infrastructure for the Agentic Economy.

KYDE makes AI agents trustworthy enough to hand them real responsibility. It prevents what an agent must not do, proves what it did, and keeps your knowledge yours.

Not on the machine. Not in the agent. KYDE sits outside, in the request path between your agents and every LLM provider — every action intercepted, scoped, and signed before it executes. Outside the agent. Cannot be overridden.

Zero code changes. One environment variable. Provider-agnostic, MCP-ready, <100 ms target latency.

• PREVENT — Before the damage. Deny-by-default at the boundary: out-of-scope requests blocked in real time, every action attributed to a verified agent identity, PII masked by role. The damage doesn't happen first and get explained later. It never happens.
• PROVE — After the action. An audit trail that is architecturally independent of every LLM provider: Ed25519-signed, hash-chained, captured at the boundary, undeletable by any agent. The suspect can't write the police report.
• RATE — Across the network. The KYDE Trust Score™: agent behavior rated across every provider in the same currency. Vendors grade their own homework. We grade behavior. Trust that can be measured can be priced — and insured.

KYDE Gateway Starter — free, self-hosted, source-available. Docker Compose plus one environment variable gives you an independent witness for every agent action: dashboard, hash-chained append-only ledger, coverage indicator, DLP alerts, compliance exports. Works with OpenAI, Anthropic, Google, and local models.

Gateway Enterprise adds inline enforcement, HSM-backed signing, deny-by-default role scoping, per-tool MCP policy, and the Trust Score™ with Coverage Report.

Where failure has consequences: finance & banking, insurance, healthcare, public sector, critical infrastructure, manufacturing. Built for NIS-2, DORA, the EU AI Act, and GDPR from day one — built with regulated industries, not for them.

Your agents are a workforce. Your workforce is critical infrastructure. Govern accordingly.
