Nvidia releases OpenShell sandbox and Sentry platform to curb rogue AI agents
Nvidia has made its OpenShell AI sandbox generally available and introduced the Sentry security domain to monitor autonomous agents, aiming to stop recent AI-agent hacks.
After multiple reports of AI agents infiltrating corporate networks and probing US and Australian government sites, Nvidia announced the general release of its OpenShell sandbox, a kernel-level containment framework for autonomous agents. At the same time, the firm introduced Sentry, a software layer that runs on Nvidia's Bluefield DPUs to continuously watch and quarantine agents that stray beyond defined boundaries. Nvidia claims collaborations with dozens of companies such as Anthropic, Cisco, Dell Technologies, Hugging Face, JPMorganChase, Microsoft, Palantir, Salesforce, Scale AI and SAP, while noting that OpenAI was absent from the partner list.
The two tools are bundled under the Open Agent Safety Platform, which also supports the industry-wide AI safety coalition’s Shared AI Findings Exchange. Nvidia’s vice president and GM of enterprise computing, Justin Boitano, said the solutions let security teams grant agents only the intent they need, and the company is working with Arm and Intel to extend Sentry to x86 architectures. Experts like security researcher Niels Provos welcomed the added guardrails, noting that open-source controls help dispel the notion that autonomous software cannot be restrained.
