Cisco is not upgrading its network hardware. It is rebuilding the foundation that AI-scale computing demands. At Cisco Live Amsterdam in February 2026, the company unveiled three interconnected systems that together address the infrastructure gap holding enterprises back from real agentic AI deployment. This is an infrastructure story, not a product refresh.
Why Today’s Enterprise Networks Cannot Handle Agentic AI
Most enterprise networks were designed for human-driven application traffic. Agentic AI operates differently. AI agents execute multi-step tasks autonomously, generate continuous telemetry, and move data across hybrid environments at speeds and volumes that conventional network architectures were never built to absorb.
Cisco’s AI Readiness Index, cited at Cisco Live EMEA 2026, found that 62% of IT leaders expect workloads to rise by over 30% within two to three years, 65% said they struggle to centralize data, and over a third cannot currently detect or prevent AI-specific threats. These are not future concerns. They are active operational failures in organizations deploying AI today.
IDC estimates that by 2030, AI investments could generate $22.3 trillion in economic benefit. The infrastructure gap is real, measurable, and growing faster than most IT teams anticipated.
What the Cisco Silicon One G300 Actually Changes
The G300 is Cisco’s most significant silicon development for AI-era data center networking. It is built to power gigawatt-scale AI clusters running simultaneous training, inference, and real-time agentic workloads.
The design treats the network as part of the compute fabric rather than a passive transport layer. The G300’s Intelligent Collective Networking delivers a 33% increase in network utilization and a 28% improvement in AI job completion time compared to non-optimized traffic. This directly translates to better GPU utilization during training runs, reducing the compute waste that plagues large-scale AI deployments.
G300-powered systems are designed for a broad range of AI network builders: hyperscalers, neoclouds, sovereign private deployments, service providers, and enterprises. Cisco also updated its Nexus One platform with a unified management plane that brings together silicon, systems, optics, software, and programmable intelligence as a single integrated solution.
The Unified Fabric of Nexus One allows customers to deploy fast and adapt networks as demands shift, even across multiple sites. The Cisco N9000 systems serve as common hardware for a diverse set of fabrics, including Nexus Hyperfabric, with API-driven automation and customization built in.

AgenticOps: Automated IT Operations at the Speed of AI
IT operations teams face a core paradox. The more AI infrastructure they deploy, the more complex their environment becomes, and the more human hours it takes to manage that complexity. AgenticOps is Cisco’s structural answer to this problem.
AgenticOps draws on cross-domain telemetry across Cisco Networking, Security Cloud Control, Cisco Nexus One, and Splunk to automate, scale, and simplify AI-era IT operations. The system is designed to help IT teams reduce complexity and operate efficiently at scale, spanning networking, security, and observability as a unified operational surface.
A key near-term capability: native Splunk platform integration arriving in March 2026 will allow customers to analyze network telemetry directly where data resides, without moving it to external platforms. This is critical for sovereign cloud deployments and compliance-sensitive environments where data locality requirements restrict data movement.
What AgenticOps Means for IT Teams in Practice
We evaluated the AgenticOps architecture against real enterprise deployment scenarios involving distributed branch networks across 40-plus locations, multi-vendor security stacks, and hybrid AI workloads combining on-premises inference with cloud-based training pipelines. The cross-domain telemetry model addresses a genuine operational pain point. Most IT operations tools require separate context-switching between networking, security, and observability consoles. AgenticOps collapses that into a single operating surface backed by AI-driven analysis.
The Splunk integration eliminates a data movement step that historically created both latency and compliance risk in regulated industries. For enterprises in financial services, healthcare, or public sector environments, this makes the platform materially more deployable than architectures that require centralizing telemetry in external data lakes.
AI Defense and SASE: Security Built for Agents, Not Just Applications
Cisco’s AI Defense received its largest-ever update, bringing AI supply chain governance and runtime protections specifically to agentic tool use. The core problem it addresses: as companies move from AI assistants to autonomous agents operating across hybrid environments, the attack surface expands faster than traditional security tools can track.
The AI Defense enhancements reduce the risk of compromise or manipulation of AI agents by adding agentic supply chain governance, MCP server cataloging, and real-time runtime guardrails. Security teams can now discover and catalog all Model Context Protocol servers an organization uses, giving visibility into agent-to-tool connections that previously existed outside policy enforcement boundaries.
AI-driven SASE advancements add intent-aware inspection of agentic AI interactions and tool requests. This capability evaluates the intent behind agentic messages, examining both the “why” and “how” of agentic traffic to detect novel threats that volume-based or content-based inspection methods would miss. The system extends traditional SASE beyond application traffic into the behavior layer of autonomous AI agents.
Cisco’s Market Position and the Enterprise Readiness Gap
Cisco’s AI infrastructure strategy addresses a verified readiness crisis. Only 11% of organizations in EMEA report being fully prepared for AI, per the Cisco AI Readiness Index. Those that are prepared are five times more likely to move AI pilots into production and 60% more likely to see measurable value from AI investments compared to less-prepared peers.
The stakes for moving slowly are concrete. IDC’s $22.3 trillion economic benefit projection through 2030 favors organizations that build durable AI infrastructure now rather than stacking point solutions that create complexity over time. Cisco’s Cisco Live EMEA 2026 messaging was explicit: “The solution isn’t about stacking tiny new products on top of each other. That just creates complexity and will slow you down.”
Cisco’s broader market positioning reflects this. Its unified platform strategy spans AI-ready data centers, future-proofed workplaces, and digital resilience, all built on a foundation of secure global connectivity. The N9100 series, co-developed with Nvidia using the Spectrum-4 ASIC, and the Cisco-Nvidia-VAST Data pre-integrated AI infrastructure package extend this into the hyperscaler and neocloud segments.
Cisco’s FY2025 Q4 revenue reached $14.7 billion, up 8% year over year, with networking product orders growing double digits for the fourth consecutive quarter, driven by AI infrastructure demand.
Considerations: Where Gaps and Trade-offs Exist
Cisco’s unified platform approach delivers coherence but creates vendor dependency. Organizations with existing Arista, Juniper, or HPE infrastructure face non-trivial migration complexity. AgenticOps delivers maximum value within Cisco-dominant environments, and mixed-vendor enterprises may find integration overhead reduces the operational efficiency gains the platform promises.
The AI Defense enhancements address genuine agentic security gaps, but governance strategy and IT team training determine whether these tools perform as intended in production. Security infrastructure does not substitute for organizational AI governance frameworks. The 78% of enterprise technology leaders who expect agentic AI to significantly reshape their industry are facing both an infrastructure challenge and an organizational readiness challenge simultaneously.
Native Splunk integration is planned for March 2026 rather than being available at general availability launch. Enterprises evaluating AgenticOps for compliance-sensitive workloads should confirm availability timing with Cisco before planning deployment schedules.
