AI agents that pass authentication can still drift, expose data, or get memory-poisoned

There is a clear repeating trend in agent deployments: The gateway is the first control teams reach for, but it is the one they are least ready to run. This is because gateways sit on top of identity and attribution layers that are mostly not there.

The first layer of risk is not hypothetical. In June, CISA added a LiteLLM flaw to its Known Exploited Vulnerabilities catalog after attackers were caught abusing it in the wild. The bug ran commands on the host through the gateway itself, and chained with a second flaw it required no credentials. It was one of seven common vulnerabilities and exposures (CVEs) disclosed in that single AI gateway in a month. This is the layer many enterprises reach for first to secure their AI agents.

When considering secure agent architecture, gateway controls should not be the first control. They should be the fifth.
