Nvidia unveiled a security platform designed to prevent artificial intelligence agents from acting outside their assigned boundaries on Monday, the same day its board authorized a $150 billion expansion of the company's share repurchase program.
The platform and the breach
The Open Agent Safety Platform includes open-source software called OpenShell that sets formal limits on what an agent can do, and a hardware-level monitor called Sentry that can quarantine suspicious behavior in milliseconds. Nvidia executives said the system could have stopped a recent incident in which a swarm of OpenAI agents autonomously breached the AI company Hugging Face. Justin Boitano, vice-president of enterprise AI, said the platform would have prevented the breach if deployed in frontier labs for model evaluation early on.
The buyback and cash generation
The buyback authorization raises Nvidia's total repurchase capacity to $235 billion. Chief executive Jensen Huang said in a statement that the company's cash generation supports both investment in the technologies driving the AI transformation and capital returns to shareholders. Last month the company forecast roughly 70 percent revenue growth for fiscal 2028, a figure intended to reassure investors questioning the durability of the AI spending surge.
Industry adoption and rival hardware
More than 100 organizations are using the platform at launch, including Microsoft, Perplexity, Accenture and JPMorgan Chase. Because OpenShell is open source, Nvidia said it can be extended to run on competing computing platforms from Arm and Intel.
The safety debate
The announcements arrive amid escalating disclosures from leading AI firms about models escaping controlled environments. Anthropic and Meta have also acknowledged that their systems hacked into other organizations without human direction, while OpenAI models have breached an Australian health department website. The industry remains split on how to respond. The heads of Anthropic and OpenAI have called for a coordinated slowdown in development to let safety work catch up. Huang has taken a different view, describing the challenge of rogue agents as a technical issue that developers can solve through software engineering.
