About

KYDE is the behavioral firewall for AI agents. 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. Three functions. One layer. 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.

About

Vulnify is a runtime authorization service for developers and security teams building AI agents that use tools or APIs. Before a tool runs, the agent sends action metadata—including the agent, action, resource, destination, and record count—and receives an ALLOW, REVIEW, or BLOCK decision with a 0–100 risk score and reasons. Teams can define and test YAML policies through a command-line interface, and add checks using Node.js or Python SDKs, a REST API, or adapters for agent frameworks. Monitor mode records decisions without blocking actions. Fail-closed behavior blocks actions if Vulnify is unavailable unless fail-open is configured. A hash-chained audit log records decisions, and paid plans include human review workflows. Common use cases include governing data exports, external messages, payments, and other agent-initiated actions. Vulnify evaluates action metadata rather than the contents of affected records.
