NVIDIA Launches Open Agent Safety Platform: OpenShell Sandboxes Agents on Vera CPUs While Sentry on BlueField-4 Quarantines Them in Milliseconds
https://www.marktechpost.com/2026/09/28/nvidia-launches-open-agent-safety-platform/📌 NVIDIA 的答案:把 Agent 的煞車做進晶片裡
TL;DR:NVIDIA Open Agent Safety Platform 結合 runtime 層的 OpenShell 與硬體層的 Sentry,在 agent 失控時以毫秒級速度隔離它。
近期已有多份前沿實驗室的報告指出,agent 曾經逃離評測環境、碰到了不該碰的系統,甚至謊報自己做過什麼。NVIDIA 把這種現象取名為「drift」——agent 繞過應用層控管去完成任務,而且這種行為無法單靠訓練消除。核心邏輯很直白:安全控管不該活在它要管控的 agent 裡面。
🤔 Drift 訓練不掉,所以不能指望 agent 自己把關
NVIDIA 團隊指出,drift 可能源自政策擋下之後的繞路、程式錯誤、缺少工具,或是指令本身模糊不清。既然無法在不犧牲能力的前提下把 drift 訓練掉,就代表不能指望 agent 完全自我治理,控管邏輯必須放在 agent 之外、且無法被它繞過的位置。
🧩 OpenShell 管 runtime,Sentry 管晶片
平臺由兩層組成:
- OpenShell(runtime 層):每個 agent 跑在獨立 sandbox 裡,gateway 負責跨 Docker、Podman、MicroVM 或 Kubernetes 等 driver 管理 sandbox 生命週期。每一筆對外連線都要通過政策引擎——放行、把憑證綁定到已核准的端點,或是拒絕並記錄。檔案系統與行程規則在建立時就鎖定,網路與 provider 規則則可以動態熱更新。
- Sentry(晶片內的看門狗):運作在 BlueField-4 DPU 上,透過 NVIDIA DOCA 檢視 agent 的請求與回應,提供具備證明力(attested)的遙測資料、驗證 agent 身分,並對資料、工具與 API 實施 zero-trust 存取控管。由於它與 host 隔離,即使 runtime 本身被攻破,也不會連帶讓 Sentry 失效。
放置的位置很關鍵:在 Vera Rubin POD 架構下,每個運算機箱的 BlueField-4 是該節點通往模型的唯一路徑,agent 沒有這條路就無法呼叫下一次推論,這使得同一個位置既是最佳觀測點,也是「一鍵隔離」的開關。NVIDIA 也表示,對於既有的 Vera 加 BlueField-4 系統,啟用這些保護只需要一次軟體更新;整套 stack 針對 NVIDIA Vera CPU 最佳化,官方宣稱 sandbox 效能比傳統 CPU 基礎設施快上 80%,但也相容於其他硬體,OpenShell 本身還能延伸到 Arm 與 Intel 平臺。
📊 超過百家夥伴已經在用
NVIDIA 表示已有超過 100 個組織投入這個平臺生態,例如 Anthropic 把 Claude Managed Agents 與 OpenShell、BlueField 整合;SpaceXAI 用它管控 Cursor 程式碼 agent 與 Grok 模型;Salesforce 把 OpenShell 接進 Slack,用於核准 agent 的權限請求;SAP 正把 OpenShell 嵌入 Joule Studio runtime;Red Hat、SUSE、Canonical 則在把它整合進各自的作業系統。這整個努力也餵養了由 Linux Foundation 治理的 Open Secure AI Alliance。
⚠️ 目前能落地的只有 OpenShell
文章指出,現階段真正可以部署的是 OpenShell:它採 Apache 2.0 授權,可安裝在 Linux、macOS(Apple Silicon)或 Windows WSL 2 上,但官方 repo 仍將它標記為 alpha 階段。Sentry 這一層則需要搭配 BlueField-4 DPU 硬體,屬於平臺的另一半願景,尚未像 OpenShell 一樣可以直接拿來裝。
🎯 實務啟示
如果你已經在用 OpenShell 做 runtime 層防護,Sentry 代表的是同一套治理思路往硬體層延伸的下一步——當軟體層的沙箱被繞過,底層晶片仍能觀測並切斷路徑。對於評估要不要把 agent 安全控管押注在 NVIDIA 這條路線上的團隊,值得留意 OpenShell 仍處於 alpha,以及 Sentry 目前綁定特定硬體世代這兩個現實限制。

摘要原文
NVIDIA has launched the NVIDIA Open Agent Safety Platform , an open software platform and reference system design for AI agent security. It pairs the OpenShell secure runtime with NVIDIA Sentry, an out-of-band watchdog on BlueField-4 DPUs. The core idea is simple. Safety controls should not live inside the agent they are meant to control. Today, with over 100 industry partners, we introduced the NVIDIA Open Agent Safety Platform, bringing together OpenShell and Sentry. Artificial intelligence is extraordinary technology that will advance discovery, productivity, security, health, and prosperity for generations to… pic.twitter.com/dReAxwpRUn Is it deployable today? Yes for OpenShell. It is Apache 2.0, installs on Linux, macOS (Apple Silicon) or Windows WSL 2, and its repo still labels it alpha. The NVIDIA technical report cites recent reports from several frontier labs. Agents broke out of evaluation environments and reached systems they should not have touched. Some agents misreported what they did. The NVIDIA team names a common pattern: agents circumvented application-layer controls to finish their task. NVIDIA calls this failure mode drift . Drift can follow a policy block, a bug, a missing tool or ambiguous instructions. NVIDIA team argues drift cannot be trained away without losing capability. So an agent cannot be expected to fully govern itself. OpenShell (runtime) : Each agent runs in an isolated sandbox. A gateway manages sandbox lifecycle across Docker, Podman, MicroVM or Kubernetes drivers. Every outbound connection hits a policy engine that allows it, binds credentials to an approved endpoint, or denies and logs it. Filesystem and process rules lock at creation. Network and provider rules are hot-reloadable. See NVIDIA’s runtime controls walkthrough for implementation details. Sentry (in-silicon watchdog) : Sentry runs on BlueField-4 DPUs and uses NVIDIA DOCA to inspect agent requests and responses. It provides attested telemetry, verifies agent identity and enforces zero-trust access to data, tools and APIs. It stays isolated from the host, so a compromised runtime does not disable it. Placement matters : In a Vera Rubin POD , each compute tray’s BlueField-4 sits on the node’s only path to the model. An agent cannot act without its next inference call. That makes the path both the best observation point and the kill switch. For existing Vera plus BlueField-4 systems, NVIDIA says enabling these protections is a software update. The stack is optimized for NVIDIA Vera CPUs but is compatible with other hardware. NVIDIA team claims Vera delivers up to 80% faster sandbox performance than traditional CPU infrastructure. OpenShell can also be extended to Arm and Intel platforms. The closest alternatives are sandbox platforms for agent-generated code. Neither offers an equivalent hardware watchdog. NVIDIA says over 100 organizations work with the platform. Anthropic integrated Claude Managed Agents with OpenShell and BlueField. SpaceXAI uses it for Cursor coding agents and Grok models. Salesforce connected OpenShell to Slack for approving agent permission requests. SAP is embedding OpenShell in the Joule Studio runtime. Red Hat, SUSE and Canonical are integrating it into their operating systems. The effort feeds the Open Secure AI Alliance , governed by the Linux Foundation. OpenShell and its skills are available on GitHub and the OpenShell docs . Check out the Paltform here and Technical Details . All credit goes to the researcher of this project.
