NVIDIA Sentry is a security framework that monitors AI agents and enforces policies governing their access to models, tools, and data from hardware isolated on NVIDIA BlueField-4 DPUs. It uses DOCA Tower, an Envoy-based transparent proxy, to inspect all agent-model communications at the application layer. DOCA Argus provides out-of-band memory introspection for real-time visibility into each agent’s execution environment and operational state. A policy engine using Open Policy Agent evaluates access requests against defined policies, combining network context with runtime evidence. The framework produces attested telemetry and tamper-evident records outside the agent’s and host’s reach for audit and incident response.
