Radio With No Radar: Why Agent Runtime Security Fails Without the Layers Beneath It
Summary
The article argues that agent runtime security products, which promise to stop malicious agent actions in real time, only work for agents whose traffic passes through an enterprise-owned gateway. Most agents bypass such gateways, creating a blind spot. It illustrates this with a case where an employee asked an AI assistant to trigger a mass-email automation.
IFF Assessment
The gap in runtime enforcement coverage for agents that bypass enterprise gateways leaves defenders without visibility or control over a growing class of AI actions.
Defender Context
Defenders should not rely solely on gateway-based agent runtime controls, since many agents never route through owned infrastructure. Watch for agent actions that bypass proxies, such as direct API calls or unmanaged SaaS automations, and invest in identity, least-privilege permissions, and audit logging at the underlying systems. The trend points to layered agent governance rather than a single real-time enforcement point.
