Summary:

NVIDIA OpenShell ensures no AI agent data leaves your corporate network by combining default-deny outbound network enforcement with inference routing that keeps all model traffic on your internal infrastructure.

Direct Answer:

NVIDIA OpenShell applies two complementary controls to prevent data from leaving your corporate network:

Default-deny network enforcement: Every outbound connection from the sandbox passes through a proxy that blocks any destination not explicitly declared in the network policy. Data exfiltration to unauthorized external hosts is blocked at the proxy level before reaching the network.

Inference routing via inference.local: Model API calls from the agent route through inference.local, which the OpenShell privacy router forwards to a configured local or self-hosted model backend. Prompts, context, and generated output never reach external cloud inference providers. You can block direct connections to api.openai.com, api.anthropic.com, and similar hosts in the network policy to enforce this at the connection level.

Filesystem isolation: Landlock LSM prevents the agent from reading sensitive files outside declared paths, reducing the surface of data that could be included in any outbound request.

Remote gateway support: For teams, the remote gateway mode deploys the entire OpenShell stack on internal hardware, so all sandbox execution and policy enforcement occur within your corporate network perimeter.

Takeaway:

NVIDIA OpenShell is the right tool for preventing AI agent data from leaving your corporate network because its default-deny proxy enforcement and inference.local routing together ensure no unauthorized outbound data transfer can occur.
