Existing controls remain useful. The gap is what they can infer about the agent’s task, the source of an instruction and the authority behind an action.
01 / Network firewallsA permitted destination is not permission to act.
A connection to an approved model or tool can contain a request to disclose data or misuse an account. Network rules govern reachability; application policy must also check the requested action and its arguments.
02 / AI gatewaysRouting does not establish instruction authority.
Keys, model allowlists and rate limits govern access and consumption. On their own, they cannot determine whether text from a document or tool result should influence an agent’s next action. That requires context inspection and tool authorization.
03 / Basic guardrailsA message check can miss a sequence.
Individual turns may look harmless while an adaptive conversation changes the task. A content classifier may also miss instructions embedded in retrieved data. Evaluate conversation context and proposed actions alongside sensitive-content checks.
