NVIDIA launches Open Agent Safety Platform: open-source OpenShell runtime plus Sentry watchdog

NVIDIA on 28 September 2026 launched the Open Agent Safety Platform, an open software platform and reference system design for keeping AI agents inside set boundaries. It pairs NVIDIA OpenShell, an open source agent runtime, with NVIDIA Sentry, a watchdog that runs on BlueField-4 DPUs.

From the NVIDIA press release, Jensen Huang: "AI's extraordinary potential for society will only be realized if we solve AI safety." The release says recent agent incidents share one pattern: "the agent circumvented security controls at the application layer to complete its assigned task."

The OpenShell 0.1.0 technical post describes three parts. A Gateway manages sandboxes and their policies. A Supervisor sits outside each sandbox and checks outbound requests against policy. The Sandbox applies kernel-level file and process controls and has no network path except through the supervisor. The supervisor can inspect HTTP, GraphQL, and MCP traffic, so a policy can allow a read and block a write on the same API. Decisions are logged in an OCSF audit trail. New in 0.1.0 is a policy prover that uses formal logic to check whether granted permissions stay inside the intended boundary. NVIDIA lists Codex, Claude Code, Pi, and Hermes as supported agent frameworks. Code is at github.com/NVIDIA/OpenShell.

Sentry is the hardware layer. The release says it runs out of band on BlueField-4, is built on DOCA, and can quarantine an agent that moves outside its software boundary "in milliseconds." NVIDIA's platform page says OpenShell also runs without BlueField-4 on local, on-premises, cloud, and Kubernetes setups, and that Vera CPUs run sandboxes up to 80% faster than traditional CPU infrastructure. The New Stack reports that Sentry itself is not open source.

Named partners include Anthropic (Claude Managed Agents integrations with OpenShell and BlueField), SpaceXAI (Cursor coding agents and Grok models), Salesforce (OpenShell approvals inside Slack), SAP (Joule Studio runtime), and Scale AI. NVIDIA says more than 100 organizations work with the platform's technologies.

Key facts

• Official primary: NVIDIA press release, 28 September 2026
• Runtime: OpenShell 0.1.0, open source, on GitHub
• Hardware layer: Sentry on BlueField-4 DPUs, optional
• Platform: tuned for Vera CPUs; NVIDIA says OpenShell can extend to Arm and Intel systems
• Governance: tied to the Open Secure AI Alliance under the Linux Foundation

How to read

OpenShell is the piece any team can try now. Sentry needs BlueField-4 hardware. The millisecond quarantine figure and the 80% Vera sandbox figure are NVIDIA claims, not independent tests. Partner lines describe integrations and plans, not audited deployments.
