NVIDIA details Sentry framework for hardware‑isolated AI agent monitoring on BlueField‑4
NVIDIA Sentry is a security framework in the OpenShell reference architecture that monitors AI agents from a hardware‑isolated trust domain on BlueField‑4 DPUs. It uses DOCA Tower (an Envoy‑based transparent proxy) for TLS termination and policy checks, DOCA Argus for real‑time memory introspection, DOCA Flow for in‑silicon layer‑4 firewalling, and specialized AI models to classify agent communications and contain misbehaving agents in milliseconds, while preserving attested telemetry for forensics and integration with enterprise security tools.
