NVIDIA Sentry moves AI-agent enforcement onto BlueField-4
NVIDIA Sentry is a planned runtime-security framework that places AI-agent monitoring and policy enforcement on BlueField-4 DPUs outside the host. DOCA Flow, Tower and Argus inspect network traffic and runtime context, while Open Policy Agent evaluates access in memory. NVIDIA says violations can be quarantined in milliseconds, with availability planned early next year.
