TL;DR: Approved agent actions can still outrun review even with AI gateways in place, JetStream Security notes. Runtime authorisation and action-level policy are needed when live behaviour must be checked against the authorised blueprint before a tool call completes.
Editorial analysis by NHI Mgmt Group, based on content published by JetStream Security: “An AI Gateway Is Insufficient Security Without a Control Plane”.
Key questions
Q: Why do agentic systems need runtime authorisation instead of static permissions?
A: Static permissions describe what an agent can generally reach, but runtime authorisation decides whether that specific action, at that specific moment, is acceptable.
Q: How should teams govern MCP tools that expose both safe and destructive actions?
A: They should treat the tool surface as a privilege boundary and authorise specific functions, not the whole connector.
Q: What breaks when an AI gateway lacks enterprise governance features?
A: Without enterprise governance, teams often lose auditability, enforceable access control, and consistent policy enforcement.
Practitioner guidance
- Define the control plane boundary Separate transport handling, identity proofing, approved design validation, and action authorisation so each control has a distinct enforcement point.
- Inventory every agentic integration path Map which agents, MCP servers, datasets, and cloud services can execute without human approval, then identify where policy is only logged rather than enforced.
- Bind policy to the action, not only the session Set controls at tool and parameter level so a permitted read action cannot implicitly grant delete, write, or exfiltration capability.
Bottom line: AI gateway adoption does not remove the need for runtime authorisation, because authenticated agent requests can still execute unsafe actions.

AI gateway-only governance is an incomplete control model: A gateway can route, log, and lightly constrain traffic, but it does not answer whether the action itself was authorised at runtime. Once agents can choose tools and continue acting without a new human gate, the control boundary has to move from transport to action. The practical conclusion is that gateway adoption without action-level policy leaves a governance gap that will surface as soon as an approved agent behaves outside expectation.
A question worth separating out:
Q: How do organisations decide whether an AI control plane is necessary?
A: An AI control plane becomes necessary when the organisation needs to decide whether a request should move at all, based on who is asking, what approved design authorises them, which tool is involved, and what the action will do. If those decisions are separated from transport, the gateway alone is not enough.
