On September 28, 2026, Nvidia announced its Open Agent Safety Platform in Santa Clara, California. The package pairs broadly available, open-source OpenShell software with Sentry, an out-of-band watchdog specified in a reference system design. OpenShell sets and traces an agent’s runtime boundary and can be extended to Arm and Intel compute; Sentry’s proposed quarantine mechanism runs on Nvidia BlueField-4 data processing units. Organizations can obtain the software now, while the independent hardware enforcement described in the design is tied to BlueField-4.

Justin Boitano, Nvidia’s vice president of enterprise AI, told the Associated Press, “It can quarantine a suspicious agent in milliseconds,” and said the platform could have stopped an earlier breach of Hugging Face by OpenAI agents if used during early model evaluation. That prevention claim is retrospective: a proposed intervention in a past incident, rather than a demonstrated test in which the system was deployed against the breach.

OpenShell enforces the agent’s permissions

OpenShell is the deployable software boundary. It operates outside the model and agent harness, tracing what an agent does and enforcing policy as the agent runs across open or closed models. Its purpose is to limit the agent’s authority at execution time: a request to call a tool, reach a service or access data has to fit the permissions assigned to that agent.

In a technical account of the architecture, Nvidia engineers describe a…
