History
Founding and early years
Cisco was founded in 1984 by Leonard Bosack and Sandy Lerner, two computer scientists at Stanford University, with the aim of connecting different local area networks that used distinct protocols. The founders pursued a practical vision of turning disparate networks into a single, scalable architecture. The company grew out of a research project and soon began selling routing products that helped networks communicate more efficiently. The early success established Cisco as a pioneer in internally routed communication and network interoperability. See Stanford University for the academic milieu that underpinned the founding, and Cisco Systems as the evolving corporate identity.
Growth through the 1990s
During the 1990s, Cisco expanded rapidly as the internet emerged from a research network into a global commercial backbone. Its line of routers and switches became the de facto standard for many enterprise and service-provider networks, enabling large-scale connectivity and management. The company began to diversify its offerings into switching, security, wireless, and management software, positioning itself as a one-stop provider for network infrastructure. Cisco’s growth was accompanied by a series of strategic acquisitions that broadened its technology footprint and global reach. See Cisco Systems and Open Systems Interconnection for the technical frameworks that underpinned this expansion.
Acquisitions and strategic shifts (late 1990s–2000s)
In 1999, Cisco acquired Cerent for about $6.9 billion, a landmark deal that reinforced its position in optical networking and next-generation access devices. The company also moved into consumer networking by purchasing Linksys in 2003, a decision that broadened brand recognition and helped drive the consumer market for home networking gear. Later, Cisco expanded into cable and video equipment through the acquisition of Scientific Atlanta in 2006. These moves underscored Cisco’s strategy of integrating hardware, software, and services under a single umbrella to serve both enterprise and consumer ecosystems. See Cerent and Linksys for related corporate history, and Scientific Atlanta for the cable and video segment.
Focus on software, security, and cloud (2010s–present)
The 2010s marked a shift from pure hardware emphasis toward software, security, and cloud-enabled networks. Cisco acquired Meraki in 2012 to accelerate cloud-managed networking, expanding its footprint in small and medium-size deployments while delivering centralized management. In 2015, Cisco announced its purchase of OpenDNS to strengthen cloud security offerings, later rebranding and integrating these capabilities into a broader security portfolio under the Cisco Secure umbrella. The company also expanded into software-defined wide-area networking (SD-WAN) with the acquisition of Viptela in 2017 and broadened collaboration and communications through the Webex platform. Other notable 2010s acquisitions include BroadSoft (2018) for cloud-based communications and Jasper (IoT platform) to extend connectivity for devices. Added emphasis on data center fabric, AI-driven analytics, and security analytics reflected Cisco’s strategy to monetize software subscriptions and services alongside traditional hardware. See Meraki for cloud networking, OpenDNS for cloud security, Viptela for SD-WAN, and BroadSoft for cloud communications.
