Hardware
Tomahawk and Jericho Ethernet switch silicon used to connect accelerators inside AI clusters.
An 800G PCIe Gen6 Ethernet network interface card built for server-to-server networking in large AI and ML GPU clusters.
A 102.4-Tbps Ethernet switch with co-packaged silicon-photonics optics, built to remove optical-I/O bottlenecks in large-scale AI clusters.
Designs and manufactures custom AI accelerators (XPUs) to a cloud operator's own specification, including the 3.5D packaging that carries them.
Cisco
Hardware
Pre-validated modular AI infrastructure bundles that combine Cisco UCS servers, NVIDIA GPUs, Nexus 9000 400G/800G switching and management software into single orderable stacks for AI inferencing, training and fine-tuning.
Turnkey on-premises AI appliance that runs real-time speech transcription for Cisco collaboration deployments locally, for customers with data-sovereignty requirements that rule out cloud AI services.
Cloud-managed full-stack AI cluster sold as hardware plus software plus service, packaging Cisco 6000 and N9300 series switches on an 800GbE back-end fabric, UCS servers with NVIDIA H200 GPUs and BlueField DPUs, optional VAST storage and NVIDIA AI Enterprise under the Hyperfabric cloud controller.
Unified programmable networking-silicon architecture for AI, hyperscale, data-centre, service-provider and enterprise routing/switching, spanning five series (G/P/E/K/A) of chip families.
No counterpart
Broadcom sells these in a stack layer with no product recorded for Cisco yet — nothing on the other side to compare them against.
Platform
Governance layer for AI agents: each agent is given a verifiable identity with an explicit mission, and a protocol-aware gateway authorizes every tool call against policy before it reaches an enterprise system, leaving an audit trail of what each agent did.
Cisco sells these in a stack layer with no product recorded for Broadcom yet — nothing on the other side to compare them against.
Application
AI assistant for contact-centre agents and supervisors that produces call and transfer summaries, live transcription, suggested chat replies, topic analytics, automatic CSAT scoring and agent burnout signals.
AgenticOps workspace where teams and AI agents collaborate to investigate, correlate and resolve issues across domains: natural-language querying, multi-step agent workflows, shared real-time visibility, and native Cisco plus third-party tool integration via Cloud Control Studio.
End-to-end AI security product that discovers an organisation's AI assets, red-teams models and applications for vulnerabilities, and enforces runtime guardrails against prompt injection and data leakage.
Agentic support intelligence delivered inside Cisco Support and Professional Services — 'the delivery vehicle for everything Cisco Support and Professional Services knows about your environment, made continuously available before you ask for it' — generally available as SaaS since April 2026 and included with existing support contracts.
AI-native workforce engagement suite for contact centres that forecasts demand and optimises shifts, uses NLP and LLMs to evaluate 100 percent of human and AI agent interactions (AI Quality Management), and runs performance coaching and AI-led onboarding simulations.
AI agent
Autonomous customer-service AI agent that handles inquiries conversationally across voice, SMS, email, chat and messaging apps and escalates to a human agent with context when it cannot resolve.
