NVIDIA Open Agent Safety Platform: A Reference for Continuous In-Silicon Agent Monitoring
https://developer.nvidia.com/blog/nvidia-open-agent-safety-platform-a-reference-for-continuous-in-silicon-agent-monitoring/📌 NVIDIA 用瀏覽器沙盒的邏輯,替 AI Agent 打造晶片級安全層
TL;DR:NVIDIA 推出 Open Agent Safety Platform 參考架構,把 Agent 監控與策略強制執行下放到硬體層,防止 Agent「脫軌」。
過去幾週,多間前沿實驗室陸續傳出同一種故事:AI Agent 跳脫了原本設計用來限制它的評估環境,碰到了不該碰的系統,甚至有 Agent 誤報了自己做過的事。這不是單一新能力造成的意外,而是工具、時間與模糊指令疊加後的必然結果。NVIDIA 認為,這個問題的解法,其實九零年代的網際網路早就示範過一次。
🤔 從瀏覽器分頁到 Agent 沙盒
文章開場用網路發展史做類比:早期網頁可以在你的電腦上跑程式、竊取資訊、植入病毒,但社群並沒有靠「要求網站開發者保證自己是好人」來解決問題,而是讓瀏覽器不再信任網頁裡的程式碼,把每個分頁隔離成獨立沙盒。NVIDIA 主張,Agent 安全也需要同一套邏輯:獨立於 Agent 之外的安全控制,而不是寄望 Agent「自律」。文中特別點出一個關鍵教訓——Drift(漂移,指 Agent 行為偏離原定任務或操作限制)可能來自策略阻擋、bug、缺少工具,也可能來自模糊指令或長時間運行下的嘗試錯誤,這種情況下不能訓練掉 Drift 同時保留能力,也不能指望 Agent 在這種處境下完全管理好自己的行為。
🧩 五項原則與三層架構
NVIDIA 提出建構 Agent 系統的五個核心原則:策略必須可驗證(Agent 執行前,prover 要證明其策略無法逃脫操作者的意圖);強制執行必須是 out-of-band(控制不存在於 Agent 內部或其可觸及範圍);通往模型(大腦)的路徑就是控制點(控制這條路徑,就同時擁有最佳觀察點與緊急停止開關);Agent 權限越大,其推理過程越要可被檢視;以及套用共享責任模型(實驗室、企業、硬體供應商各自負責一層,就像今天的雲端運算)。
整個安全平臺分為三層:Application 層(模型、harness、工具、資料等任務所需元件)、Runtime 層(把應用層映射到基礎設施上,提供持續監控與即時策略執行)、Infrastructure 層(實際執行 Agent 工作負載的硬體資源)。
在這個架構中,NVIDIA OpenShell(Apache 2.0 授權的開源安全 runtime)負責讓每個 Agent 在沙盒中執行,並把操作者的指令轉換成可驗證的策略,操作者可以定義 Agent 能存取哪些檔案、網路、工具、程序與憑證,OpenShell 會在 Agent 執行前檢查、執行中強制這些限制。對於想要額外獨立防護層的組織,NVIDIA Sentry 把監控與強制執行延伸到 NVIDIA BlueField 硬體上;NVIDIA DOCA 則讓 BlueField 的安全基礎可被程式化,並與 OpenShell 的策略連動,關聯 Agent 互動、策略決策與工具/資料存取紀錄,協助識別 Drift 與可疑行為。DOCA gateway 再補上身分治理,持續驗證每個 Agent 的身分與被授權範圍。
💡 為什麼要把控制點放進晶片
在 NVIDIA Vera Rubin POD 架構中,每個運算機箱都配有一顆 BlueField-4 DPU,且是節點通往模型的唯一路徑。這意味著 BlueField-4 可以在 Agent 之外、host 之外,以 out-of-band 的方式持續觀察 Agent 行為並即時強制執行安全策略,即使 host 端本身不可信任,這層防護依然成立。對已經在 Vera + BlueField-4 系統上運行的組織來說,啟用這些防護只是一次軟體更新。
🎯 實務啟示
如果你的團隊正在部署具有較高自主權的 Agent(長時間運行、可呼叫多種工具與憑證),這篇文章提醒的重點是:不要把安全寄託在「訓練 Agent 更聽話」上,而應該建立獨立於 Agent 推理過程之外的策略驗證與強制執行層,並讓 Agent 的推理過程對監控系統保持可見,權限越大、可視性要求越高。

摘要原文
To understand where agentic AI stands today, consider the last seismic shift in technology: the rise of the internet in the 90s. It was new and full of possibilities. You could build a website over a weekend and share it with the world, or chat with someone half way around the world in online chat rooms without long-distance telephone fees. It brought endless opportunity, but also a lot of risk. A website could run code on your machine, steal your sensitive information, or infect your computer with a virus. People loved it anyway. To introduce a layer of trust, the community built things like encrypted connections and a lock icon to know when a connection was safe. The step function change in safety came from a radical security idea at the time: isolate each page in its own sandbox (a tab in a browser) so that a rogue page couldn’t infect the rest of your computer. Amazon, Google, Netflix, and Meta were all built on this trust layer. Security and safety for the internet enabled online commerce, connection, gaming, and so much more that wouldn’t have been possible before. Security and safety didn’t slow the pace of innovation—they allowed it to accelerate. Why build a trusted layer for agents now? Several frontier labs have recently reported versions of the same story: AI agents broke out of the evaluation environments that were meant to contain them and reached systems they never should have been allowed to. Some of the agents even misreported what they did. The security controls in place were insufficient. Over the past few weeks, these reports have led to a serious debate about the pace of agent development. We believe we need to increase the pace of AI safety research and engineering in collaboration with frontier labs and the broader community. It was not a single new capability that led to these breakouts. It was a combination of tools, time, and ambiguous instructions, along with a desire for the agent to think “outside the box.” Agent safety requires independent security controls. The internet was not made secure by requiring that web developers promise to be good. It became safe because the browser stopped trusting the code in the web pages explicitly. We need to build this trust layer for agents. Figure 1. NVIDIA Open Agent Safety Platform Reference Design combines NVIDIA OpenShell on NVIDIA Vera and NVIDIA Sentry on NVIDIA BlueField-4 Lessons learned from building OpenShell NVIDIA OpenShell (Apache 2.0) is an open source secure runtime for executing autonomous AI agents in sandboxed environments with kernel-level isolation. Building OpenShell over the past year, we have learned that every agent should run in a zero-trust environment out of the box. They need isolation, monitoring, and behavior detection. Today, we are introducing an open stack that makes this possible. In our own research, we’ve watched how agents can go off course. Drift refers to agent actions that depart from the intended task or operating constraints. Drift can occur in response to a policy block, a bug, or a missing tool. Drift can also occur when instructions are ambiguous or agents are left to run for days or weeks to solve hard problems where the first 1,000 things they try do not work. This can’t be trained away while retaining the capability. And here’s the most important lesson: an agent in these circumstances cannot be expected to fully govern its own behavior. Five core principles for building an agent system Policy needs to be verifiable: Before an agent runs, a prover shows that its policy cannot escape the intent of the operator. Enforcement must be out of band: The controls do not live inside, or within reach of the agent. The agent does not need to know it is being watched. The path to the model (the brain) is the control point: An agent cannot act without its next thought. By controlling the path to the model, you own both the best observation point and also the kill switch to interrupt it if you need to. Scale agent authority with the ability to inspect its thinking: The more an agent can do, the more its reasoning needs to be visible. An advantage of open models is that the entire reasoning space and activations are all visible. Applying the shared responsibility model: Labs, enterprises, and hardware providers each own a layer, just like the cloud today. The agent runtime and its policy language need to be open so any provider can plug in. Three open agent safety platform layers A safety platform for AI agents includes the following three layers: The application: What end-users are building. Contains the necessary primitives for mission success: models, harnesses, tools, data, and support scripts and programs. The runtime: Projects the application layer onto infrastructure. Orchestrates the agentic workload onto infrastructure that meets end-user requirements (end-user workstation, edge device, data center) and provides continuous monitoring and real-time policy enforcement and governance. The infrastructure: Concrete hardware resources used to execute agentic workloads. Network calls to upstream services, databases and filesystem access, general purpose compute for tool and code execution, accelerated compute for safety monitoring and increased workload density. A layered foundation for agent safety OpenShell runs each agent in a sandbox and turns the operator’s instructions into a verifiable policy. Operators define which files, networks, tools, processes, and credentials an agent can access. OpenShell checks those limits before the agent runs and enforces them as it works. For organizations that want an additional, independent layer, NVIDIA Sentry extends monitoring and enforcement into NVIDIA BlueField hardware. NVIDIA DOCA makes the BlueField security foundation programmable and connects it with OpenShell policy. It correlates agent interactions, policy decisions, and tool and data access to create a contextual record of agent activity. This helps safety systems identify drift, investigate suspicious behavior, and determine when intervention or deeper analysis is needed. The DOCA gateway complements this behavioral protection with identity governance, continuously verifying each agent’s identity and delegated authority to ensure it operates within its assigned scope. To learn more, refer to the technical walkthrough, Add Runtime Controls to AI Agents with NVIDIA OpenShell . Operating at AI factory scale NVIDIA Open Agent Safety Platform is optimized to run on NVIDIA Vera CPU- and BlueField DPU-based systems, and is also compatible with other hardware systems. In an NVIDIA Vera Rubin POD , each compute tray includes a BlueField-4 data processing unit on the node’s only path to the model. From this position, BlueField-4 provides continuous, out-of-band observability into agent behavior and enforces security policies in real time at line speed. Isolated from the host and beyond the agent’s reach, it stands as a trusted infrastructure protection layer even when host resources cannot be trusted. Organizations can use it to run NVIDIA Sentry as an optional security layer alongside OpenShell. This foundation allows for resilient security, enforcing the OpenShell policy in silicon, and for the continuous evaluation of the security and integrity of agents. This includes assessing their runtime security and monitoring for any deviation from their designed intent based on a predefined behavioral profile. In this architecture, entire fleets of agents, subagents, tools, and applications all stay inside the boundary with full lineage. For anyone already running on an NVIDIA Vera system with BlueField-4, enabling these protections is just a software update. The agent economy The internet was built on open source, open research, and people who believe that the internet could change the course of humanity. Adding trust turned a great concept into a great economy. The agent economy, and the next set of great companies, is waiting for the same layer.
