Cisco

Cisco Systems is the world's largest networking company, providing a comprehensive portfolio of networking hardware, software, and services that form the backbone of enterprise and service provider networks. Cisco's product lines include switches (Catalyst, Nexus), routers (ISR, ASR), wireless (Meraki, Catalyst), and collaboration systems. Cisco's Meraki line provides cloud-managed networking with switches, access points, security appliances, and cameras, all managed through a single dashboard. Cisco DNA Center (now Catalyst Center) provides intent-based networking automation for campus and branch environments. The company's SD-WAN solution (from the Viptela acquisition) enables software-defined wide area networking that optimizes connectivity across branches, cloud, and data center locations. Cisco also provides extensive networking certifications (CCNA, CCNP, CCIE) that are industry standards for network professionals.
