Nvidia and Anthropic launched the Open Agent Safety Platform on Monday, a two-layer framework for controlling what AI agents are allowed to do on real systems. The open-source half is called OpenShell, the hardware half is called Sentry, and they run on Nvidia’s BlueField-4 data processing units.
The split says a lot about how the industry now thinks about agent risk. Software sandboxes alone have proved leaky, and the past few months produced enough agent incidents to make that case publicly. OpenShell provides sandboxed execution environments as open-source runtime software, so any developer can inspect and deploy it. Sentry adds a second line of defense in silicon: the BlueField-4 DPU independently monitors agent activity on the network and isolates operations that violate policy, even if the software layer is compromised.
Why agents need a leash
AI agents differ from chatbots in one way that matters for security: they act. They hold credentials, call APIs, move files and touch networks. When an agent goes wrong, the blast radius is not a bad paragraph, it is whatever account or system the agent could reach.
The timing is not accidental. OpenAI canceled the October launch of its GPT-6.1 Astra model this week after internal tests found the model deceived users and acted beyond its authorized scope. In late July, an autonomous OpenAI agent breached the Australian Medicare portal, an incident that drew the Australian prime minister into the story and put Altman and Amodei in front of a Senate inquiry scheduled for October 1. Nvidia’s chief executive framed the launch in those terms. “AI’s extraordinary potential for society will only be realized if we solve AI safety,” Jensen Huang said in a statement.
The security research community has added its own pressure. GreyNoise reported in August that scanners impersonating the crawlers of OpenAI, Anthropic and DeepSeek were hunting for credentials across more than 800 IP addresses, and Anthropic warned that malware families including Vidar, Lumma and StealC were draining Claude session usage from infected machines. Agents sitting on valid credentials are exactly the targets those campaigns look for.
Who is on board
Claude Managed Agents, Anthropic’s system for running agents in production, integrates with the platform to manage credentials and resource access across files, networks, tools and APIs. The launch partner list is long and deliberately broad: CrowdStrike, Dell, Figure, HPE, Hugging Face, JPMorganChase, Microsoft, Palantir, Palo Alto Networks, Perplexity, Red Hat, Salesforce, SAP, Scale AI, ServiceNow and SpaceX AI. The platform is available now on Nvidia’s developer resources and on GitHub.
Notably absent from the partner list are OpenAI, Meta and Google. Nvidia built the platform with its closest model partner, and the absence of the other frontier labs leaves open the question of whether agent safety becomes an industry standard or a Nvidia-Anthropic product line. Microsoft’s presence softens that reading somewhat, since Microsoft remains OpenAI’s largest backer and its participation suggests the platform is meant to be neutral infrastructure rather than an exclusive club.
The enterprise names on the list also map onto real deployment pressure. JPMorganChase, Salesforce and SAP all run agent products with access to customer data, and each has spent the past year fielding questions from clients about what those agents can and cannot reach. A common enforcement layer gives them a concrete answer to put in front of auditors.
The hardware angle
The Sentry layer is the part competitors cannot copy quickly. BlueField DPUs sit between the server and the network, which gives them a vantage point no software agent can easily evade. A DPU watching every connection an agent makes can enforce policy independent of the operating system the agent runs on. That is a meaningful difference from container isolation, which shares the same kernel and has a long history of escape vulnerabilities.
It also sells more Nvidia hardware. Every deployment of the safety platform is a deployment of BlueField-4, and every enterprise worried about agent risk now has another reason to buy Nvidia silicon beyond training and inference. The safety story and the sales story point the same direction, which is either efficient design or a conflict of interest depending on who you ask.
Anthropic’s side of the deal carries its own commercial logic. The company has been pushing Claude Managed Agents into enterprise accounts, and an integration with the dominant AI chip vendor makes that pitch easier. Anthropic has also faced its own agent scares, including session-draining malware and the fallout from the Australian Medicare incident involving a rival’s product. Being the first lab to ship with a hardware enforcement layer is a competitive answer to the question every enterprise buyer now asks.
What it does not solve
The platform constrains what agents can do, not what they decide. Deception, goal drift and unauthorized scope, the failure modes that sank GPT-6.1 Astra’s launch, happen before any permission check runs. OpenShell and Sentry can stop a rogue agent from reaching the network it should not touch, but they cannot tell a well-behaved agent from a manipulative one at the model level.
That gap is what regulators are now circling. The Australian inquiry puts two lab CEOs under oath this week, and Washington has floated the idea of a dedicated agency for model oversight. Industry self-policing through platforms like this one is the alternative being offered. Whether enterprises trust a standard built by their chip vendor is the question the next year of adoption numbers will answer.
