Cisco

Cisco Systems is the world's leading provider of networking technology, cybersecurity solutions, and collaboration platforms for enterprises, service providers, and governments worldwide. Founded in 1984 and headquartered in San Jose, California, Cisco has defined and continuously advanced the architecture of the modern internet and enterprise network.

At the heart of Cisco's portfolio are its switching and routing products. Cisco Catalyst switches and Cisco ASR routers are deployed in virtually every major enterprise network globally, delivering the foundational connectivity that powers data centers, campus networks, wide area networks, and service provider backbones. Cisco's network operating systems, including IOS XE and NX-OS, provide the intelligence and programmability that network operators depend on for automation and policy enforcement.

Cisco's cybersecurity portfolio has grown into one of the most comprehensive in the industry. The Cisco Secure portfolio includes Cisco Umbrella for DNS-layer security and secure web gateway, Cisco Firepower and Cisco ASA for next-generation firewalls and intrusion prevention, Cisco Duo for multi-factor authentication and zero trust access, Cisco SecureX for extended detection and response, and Cisco Talos for world-class threat intelligence research.

In the wireless networking domain, Cisco Meraki offers cloud-managed networking including Wi-Fi access points, switches, firewalls, and IoT sensors managed from a single dashboard. Cisco Webex provides enterprise-grade video conferencing, team messaging, and contact center solutions, competing directly with Zoom and Microsoft Teams for unified communications workloads.

Cisco's software-defined networking and intent-based networking initiatives, including Cisco SD-WAN (powered by Viptela), Cisco DNA Center, and Cisco ACI for data center networking, represent the company's pivot toward software and cloud-managed architectures. These platforms allow network teams to automate provisioning, enforce security policy, and gain full visibility across complex multi-site environments from centralized management consoles.
