What Is AI Governance Proxy (AI Gateway)?
An AI governance proxy, also called an AI gateway, is a network component that routes traffic between AI agents and model providers through a single control point. Because every inference and tool call on that route passes through it, it can verify agent identity, enforce behavioral policy, and record tamper-evident evidence, without any changes to agent code. It sees what is routed through it, not what bypasses it.
Who needs this
Platform and security teams who need coverage across many agents, frameworks, and providers at once. The proxy pattern is what makes governance retrofittable: agents built last year, vendor tools you cannot modify, and scripts nobody documented all cross the same network egress, so they are all governed the moment the route changes.
Proxy vs SDK: the coverage question
The alternative to a proxy is instrumentation: wrap every agent in an SDK, add middleware to every framework. That works exactly as well as your inventory is complete, and agent inventories never are. The proxy inverts the default: instead of finding every agent and opting it in, you stand at the point they must pass to reach a provider and cover them by construction, including agents you did not know about, as long as the egress rules leave no other route.
The cost of the position is latency, which is why the enforcement path must be deterministic policy, not model calls. No LLM sits in the decision loop.
Data point · the entire deployment, from the Kyde Gateway docs
# OpenAI-style clients (VS Code, Cursor, most SDKs)
export OPENAI_BASE_URL=http://localhost:4000/v1
# Anthropic-style clients (Claude Code, Claude SDK)
export ANTHROPIC_BASE_URL=http://localhost:4000One gateway instance proxies OpenAI, Anthropic, Gemini, Copilot, and local models simultaneously; the upstream is auto-detected from the request path, auth headers pass through untouched. Target enforcement overhead: under 100ms.
