New · Jun 10, 2026·Microsoft Agent Control Specification

The Microsoft Agent Control Specification now has multicloud network enforcement.

The Microsoft Agent Control Specification (ACS) gives enterprises a single policy file for governing any agent — regardless of framework or cloud. But declaration without network enforcement is a policy document, not a security control. Aviatrix is the first multicloud network enforcement substrate for ACS-governed agents. No SDK. No code changes. Enforcement at the wire.

The Problem

The spec is open. The enforcement gap is real.

The Microsoft Agent Control Specification declares what agents are allowed to do. But declaration without enforcement is a policy document, not a security control. Three structural gaps that no in-process SDK closes.

The runtime can be deceived

A jailbroken prompt, a poisoned dependency, or a hallucinated tool call can all produce traffic that looks legitimate to the SDK. The network cannot be deceived the same way — it sees the actual destination, not what the agent believes it's doing.

Enforcement can't wait for detection

Most credential-based intrusions produce no anomalous signal — the traffic looks legitimate because valid credentials are being used. A network enforcement layer that depends on detecting a compromise first inherits every blind spot of in-process monitoring. Enforcement must hold before the alert fires.

The spec runs on every cloud

The Microsoft Agent Control Specification is not Azure-only. Agents built on it run on AWS, GCP, on-premises Kubernetes, and anywhere else enterprises deploy them. In-process SDK controls are scoped to the framework. The network is not.

How It Works

Two enforcement planes. One source of truth.

The same policy file governs both the agent runtime and the network layer. When the SDK cannot see a call — because the agent has been jailbroken or a dependency has been poisoned — the network still stops it.

01

Author your policy file

The Microsoft Agent Control Specification publishes the schema. Your team writes your own .guardrails.yaml against it — declaring the agent's allowed tool surface, model constraints, and policy boundaries. Same model as OpenAPI: the spec is centrally authored, your policy file is yours. Works across every conformant agent framework.
02

Compile to network policy

Aviatrix translates your policy file into DCF enforcement through your existing CI pipeline — Argo, Flux, GH Actions, or any runner. The Aviatrix controller reconciles it into live network policy across your cloud estate within minutes. Works on K8s (EKS, AKS, GKE) and directly via API for VM and serverless agents.
03

Enforce at the wire

Every outbound connection the agent attempts is evaluated at the network layer — destination, protocol, workload identity — independent of what the agent believes it is doing. Blocked connections are logged to CoPilot FlowIQ with full attribution.
"We built Microsoft Agent Control Specification because customers should not have to negotiate a different security model for every agent platform they adopt. The ecosystem is what makes that vision real, and Aviatrix is exactly the kind of partner we hoped would step up. Its Cloud Native Security Fabric enforces Agent Control Specification at the network layer with the pervasive, cross-platform reach no single product can match. That is how an open control plane becomes a defensible enterprise standard."

Who This Is For

Two paths. One architecture.

Existing Aviatrix customers

Already running the Controller

If you're already running Aviatrix for multicloud security, the ACS VCA extends your existing policy plane to cover every AI agent workload — no new infrastructure, no additional spend. Your SE will enable the feature flag and walk through deployment. Typically 1–2 weeks from conversation to enforcement.

Net-new to Aviatrix

ACS enforcement is the entry point

If you're evaluating agent governance and want to see the enforcement story before committing to the platform, start with the 30-day Enterprise free trial on AWS or Azure Marketplace. The ACS VCA is included. Sign up above and an SE will walk you through it.

The Enforcement Ecosystem

Microsoft authors the standard.
Aviatrix enforces it everywhere.

The Microsoft Agent Control Specification is an open standard designed for ecosystem implementation, not an Azure-only feature. The enforcement ecosystem is what gives it enterprise reach.

Microsoft

Authors the standard

The ACS publishes the schema. Your team writes your own policy file against it. Open source, MIT-licensed, designed to work across every vendor, cloud, and agent framework — not Azure-only.

  • Open specification — framework and cloud agnostic
  • Policy expressed in Rego, CEL, or Cedar — plugs into standards you already use
  • Agent Governance Toolkit — open source, released April 2026
  • Works alongside Foundry, Bedrock, Vertex, and any conformant runtime

Aviatrix

Enforces it at the network layer

The Cloud Native Security Fabric carries the same policy into live network enforcement across every cloud — including where Microsoft Foundry does not operate.

  • Destination, protocol, and workload identity enforced at the wire
  • Default-deny: agents reach only what policy explicitly permits
  • Multicloud — AWS, Azure, GCP, and any Aviatrix-connected cloud
  • CoPilot FlowIQ — every connection logged with full attribution
