Nvidia Unveils OpenShell Architecture to Contain and Monitor AI Agents

Nvidia introduced the OpenShell Reference Architecture at GTC Berlin, a full-stack design combining Vera CPUs, the open-source OpenShell runtime, and BlueField-4 chips running Sentry to contain and monitor autonomous AI agents. This architecture treats every agent workload as untrusted, isolating agents within milliseconds via Sentry, which inspects traffic from a separate hardware domain without requiring agent cooperation. Nvidia CEO Jensen Huang said OpenShell allows agents freedom within clearly defined boundaries, enabling agents to think on Rubin, act on Vera, and be governed on BlueField. Security vendors including CrowdStrike, Palo Alto Networks, Zscaler, and Check Point are integrating support, with Sentry planned for early next year availability. Enterprises can run agents from model builders such as Anthropic, Google, Meta, and OpenAI on this infrastructure.
