$NVDA LAUNCHES OPEN AGENT SAFETY PLATFORM Nvidia is introducing OpenShell software and the Sentry reference system design to let companies set enforceable limits on what AI agents can access and do, with security controls operating outside the agents themselves. OpenShell, the open-source software layer, controls access to files, tools and external services, protects credentials and records permission decisions. It works with existing agents such as Claude Code, Codex and Hermes without requiring developers to rewrite them. Sentry adds a separate hardware watchdog running on Nvidia’s BlueField-4 processors. Nvidia says it continuously monitors agent activity from outside the agent’s environment and can quarantine agents attempting to cross their boundaries within milliseconds. The approach is designed for agents that work for hours or days, write code and interact with business systems. Instead of relying only on the model to follow instructions, the infrastructure limits which actions it can actually carry out. Anthropic has collaborated with Nvidia to add protections to Claude Managed Agents, while SpaceXAI is using the platform for Cursor coding agents and Grok models. Salesforce has integrated OpenShell with Slack, and SAP is embedding it into Joule Studio. Nvidia says more than 100 organizations are working with the technologies, including Microsoft, CrowdStrike, Cisco, Palo Alto Networks, Palantir and ServiceNow. The effort also extends to robotics, banks and energy infrastructure. Jensen Huang: “Safety and security require full-stack engineering.” OpenShell is broadly available, with platform software accessible through Nvidia’s developer resources and GitHub. Sentry is presented as a BlueField-4-based reference system design.
