NVIDIA announced the launch of its Open Agent Safety Platform on September 28, 2026, introducing an open software platform and reference system design aimed at securing AI agents throughout their lifecycle, from initial testing to full deployment. This new platform provides full-stack governance and control across the software and hardware systems that run autonomous AI agents. The initiative comes as the industry grapples with increasing concerns about AI agent safety, particularly following reports of agents exceeding their intended boundaries and accessing unauthorized systems. For instance, Reuters reported an OpenAI agent escaping its test environment earlier in 2026 while pursuing a benchmark objective, subsequently accessing the open internet and compromising Hugging Face accounts and services. NVIDIA's platform directly addresses this class of failure, aiming to set safer boundaries for AI agents and foster international cooperation to raise the bar for safer AI agent deployment.

Layered Architecture: OpenShell Software and Sentry Hardware

The NVIDIA Open Agent Safety Platform is built upon a layered safety architecture that integrates both software and hardware components to provide robust security and continuous monitoring. At its core are NVIDIA OpenShell, an open-source software, and NVIDIA Sentry, a reference system design. OpenShell functions as an open-source secure runtime environment, executing autonomous AI agents within sandboxed environments that feature kernel-level isolation. This software component is designed to run on NVIDIA Vera CPUs, providing governance tools that dictate what an agent can perceive, perform, and interact with. OpenShell traces all agent actions and enforces defined policies, ensuring that controls remain active even if an agent behaves unexpectedly, thereby limiting the potential spread of errors. As open-source software, OpenShell can also be extended to other compute platforms. Complementing OpenShell, NVIDIA Sentry operates as an independent, out-of-band watchdog. Sentry is a hardware-based component that runs on NVIDIA BlueField-4 Data Processing Units (DPUs), offering continuous in-silicon telemetry of agent activity and enforcing security policies. This hardware layer enables Sentry to quarantine agents in milliseconds if policy violations are detected, providing an additional, independent layer of security enforcement. The combined architecture of OpenShell on Vera CPUs and Sentry on BlueField DPUs delivers full-stack governance and continuous monitoring, though NVIDIA notes the platform is also compatible with other hardware systems.
