Cisco Secure AI Factory with NVIDIA: Built for Performance, Security, Resiliency

Since its unveiling at GTC in March 2025, the Cisco Secure AI Factory with NVIDIA has led the industry in offering enterprises a comprehensive architecture for AI infrastructure that puts security and observability at the forefront without sacrificing performance. With Cisco AI PODs and Cisco Silicon One-powered Nexus switching as a foundation, Cisco today is delivering new capabilities and features across:

• Security and Observability - Cisco AI Defense now integrates with NVIDIA NeMo Guardrails to deliver robust cybersecurity for AI applications. Cisco AI Defense is orderable for on-premises data-plane deployment enabling security and AI teams to protect AI models and applications, limiting the sensitive data that leaves their organization's data centers. Also available, Splunk Observability Cloud helps teams to monitor the performance, quality, security, and cost of their AI application stack—including real-time insights into AI infrastructure health with Cisco AI PODs—while Splunk Enterprise Security extends this visibility to protect AI workloads.
• ● Core AI Infrastructure - Cisco Isovalent is now validated for inference workloads on AI PODs, enabling enterprise grade, high-performance Kubernetes networking. Cisco Nexus Hyperfabric AI with a new cloud-managed Cisco G200 Silicon One switch that delivers high-density 800G Ethernet, is now orderable as a deployment option in AI PODs. Cisco UCS 880A M8 rack servers with NVIDIA HGX B300, and the Cisco UCS X-Series modular servers with NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs are also now orderable as part of AI PODs. This enables high-performance GPU support for a wide range of workloads including generative AI fine-tuning, inference and more.
• Ecosystem expansion - NVIDIA Run:ai software is available through Cisco and its partners, enabling intelligent AI workload and GPU orchestration capabilities. Nutanix Kubernetes Platform (NKP) solution is now a supported Kubernetes platform, and Nutanix Unified Storage (NUS) solution is now a supported storage option, with Nutanix Enterprise AI (NAI) solution as the interoperable software component that simplifies building and operating containerized inference services.
• Government-Ready - Cisco is collaborating with NVIDIA and aligning to the new NVIDIA AI Factory for Government, a full-stack end-to-end reference design for AI workloads deployed in highly regulated environments.

The First AI-native Wireless Stack – with Cisco at its Core

As AI moves from smartphones to more connected things – augmented reality glasses, connected cars and robotics – wireless networks face mounting demand to support billions of connections at unprecedented scale and efficiency. To meet this challenge, Cisco, NVIDIA, and additional telecom partners have developed the first American AI-RAN stack for mobile networks that integrates sensing and communication, with multiple pre-6G applications being showcased at NVIDIA GTC DC. It allows telecom providers to infuse AI into their mobile networks, starting with 5G advanced services and establishes the groundwork for 6G. The stack combines Cisco's user plane function and 5G core software with the NVIDIA AI Aerial platform, creating a foundation that enables physical AI and integrated sensing with unmatched efficiency and security.
