Cisco Unveils Smart Switches with Embedded AI Security for Next-Gen Data Centers

Cisco Introduces Revolutionary Smart Switches for AI-Driven Data Centers

Cisco Systems has unveiled its new Nexus 9300 Series Smart Switches, a groundbreaking solution designed to redefine data center architecture in the age of artificial intelligence. Announced at Cisco Live EMEA 2025, these switches represent a significant leap forward in combining networking and security capabilities within a single device 1

Innovative Hardware Architecture

The Nexus 9300 Series Smart Switches feature a dual-processor design that sets them apart from traditional networking hardware:

1. Cisco Silicon One E100 network processors for high-performance data transfer
2. Programmable AMD Pensando data processing units (DPUs) for security and additional services

This unique architecture allows for intelligent traffic steering between the two processing engines, optimizing performance and enabling the integration of advanced services directly into the switch fabric 1

Embedded AI-Powered Security with Hypershield

A key feature of the new Smart Switches is the integration of Cisco Hypershield, an AI-native security system embedded directly into the data center fabric. Hypershield leverages the embedded DPUs to provide distributed security capabilities, including:

• Autonomous segmentation
• Real-time exploit protection
• Continuous updates
• Micro-segmentation and policy enforcement across the infrastructure 2

This approach allows for the creation of a "micro perimeter" around each service within a workload, significantly enhancing overall security posture 3

Simplifying Data Center Architecture

The Smart Switches address the growing complexity of data center management, particularly in light of increasing AI workloads. By embedding services directly into the switching layer, Cisco aims to:

1. Reduce the number of separate appliances required
2. Simplify infrastructure design
3. Enable more efficient power consumption and cooling
4. Improve total cost of ownership
5. Provide enhanced visibility across the data center 1

Flexible Deployment and Management

The new switches can be deployed as regular switches or with advanced features enabled. This flexibility allows customers to scale up or adapt to changing IT needs without adding more hardware. Management of the switches is integrated into existing paradigms:

• Network teams manage the lifecycle of the switches
• Security operations teams have access to the DPU for enabling security services 3

Policies can be managed through the Cisco Hybrid Mesh Firewall, with updates applied automatically to the appropriate enforcement points 2
