Cisco

Cisco is a global technology company that develops networking, security, collaboration and observability products. Its systems connect users, devices, applications and data across offices, data centres, service-provider networks and cloud environments. Cisco serves enterprises, telecommunications companies, governments and smaller organisations, combining hardware with software subscriptions, technical support and professional services.

The company’s networking portfolio includes switches, routers, wireless systems, software-defined networking and tools for managing campus, branch and data-centre infrastructure. Cisco Security covers identity, network protection, cloud security, threat detection and secure access. Webex provides meetings, calling, messaging and contact-centre services. The company also owns Splunk, whose software is used for observability, security operations and machine-data analysis. Cisco’s service-provider technology supports internet, mobile and high-capacity network operations.

Cisco was founded in 1984 by Leonard Bosack and Sandy Lerner, who worked at Stanford University. The company became a major supplier during the commercial expansion of computer networking and the internet, with routers forming the foundation of its early growth. It later expanded into switching, wireless networking, communications and security. Acquisitions have remained important to its strategy, adding companies such as Meraki, ThousandEyes and Splunk to its platform.

Cisco lists its corporate headquarters at 3098 Olsen Drive, San Jose, California 95128, United States, while 170 West Tasman Drive remains a legal mailing address. Its published corporate telephone number is +1 408 526 4000. Sales and technical support use separate regional contacts and online service portals.

For the most current product, office and support information, visitors should use the official Cisco website, because regional availability and contact routes can change. Corporate services and product availability can differ by market.
