Nvidia Gives Banks a New Way to Stop AI Agents From Crossing the Line | PYMNTS.com

The company’s Open Agent Safety Platform, announced in a Monday (Sept. 28) press release, combines software restrictions with an independent hardware watchdog. For banks and payments providers exploring agents that can initiate transactions or access sensitive records, the approach offers a foundation for enforcing permissions outside the AI model itself.

The financial services implication is straightforward. Giving an agent instructions about what it may do is only one part of controlling it. Businesses also need systems that prevent the agent from reaching tools or taking actions beyond its authority.

Nvidia OpenShell software creates a controlled environment around an agent, traces its actions and enforces operating rules. Sentry, a separate watchdog running on Nvidia’s BlueField-4 data processing hardware, monitors behavior independently. Sentry can quarantine and stop an agent within milliseconds if it attempts to escape its software boundary, per the release.

That separation is central to the design. Nvidia’s technical description said operators define which files, networks, tools and credentials an agent can access. OpenShell checks and enforces those limits. The additional hardware layer can verify the agent’s identity and delegated authority while…
