Cisco at ONUG 2026 Proposes Integrated Networking and Security Architecture for AI Data Centers
Summary
At ONUG 2026, Cisco outlined its blueprint for AI-native infrastructure, focusing on the data center in the Agentic AI era. The core strategy is to integrate networking and security by offloading security policies (e.g., firewalls, segmentation) to DPUs and leveraging AI-driven operational models to meet the dual demands of high performance and robust security isolation for AI workloads.
Key Takeaways
SVP Tom Gillis will keynote on how networks must adapt for machine-to-machine intelligence and autonomous agent operations.
The technical highlights include: 1) Implementing L4 workload micro-segmentation with policies following workloads via Cisco Nexus One and N9300 Series Smart Switches. 2) Integrating Cisco Hybrid Mesh Firewall with NVIDIA BlueField DPUs to deliver server-level, line-rate stateful firewall protection without impacting GPU/CPU performance. 3) Leveraging AI Canvas and the Deep Network Model for AI-driven "AgenticOps" for troubleshooting and optimization.
These moves aim to build an AI infrastructure that delivers both "unprecedented scale" and "deep, pervasive security."

Why It Matters
This signals a shift in the core control layer of AI infrastructure from traditional, separate networking and security appliances towards an "integrated control plane" where networking and security are deeply fused and offloaded to DPUs/SmartNICs. Cisco is attempting to define the new standard for data centers in the AI era.
PRO Decision
**Control Layer Shift**
- **Vendors**: Must assess capabilities to integrate security and networking policies on DPUs/SmartNICs. Vendors not participating in building this fused control layer risk irrelevance in high-performance AI computing scenarios.
- **Enterprises**: Need to re-evaluate existing data center architecture, considering "DPU-level fusion of networking and security" as a key criterion for AI infrastructure procurement and design over the next 12-18 months.
- **Investors**: Watch for value migration from standalone network security hardware to software-defined capabilities integrated into compute/networking silicon (DPUs, SmartNICs). Monitor moves by major cloud and chip vendors in this direction.
