Cisco Systems makes the network gear -- routers, switches, and servers as well as software -- that moves information around the internet and corporate networks. The company, which has dominated the market for internet protocol-based networking equipment, also makes security devices, internet conferencing systems, set-top boxes, and other networking equipment to businesses and government agencies. Software that controls networks has become an increasing focus for Cisco, which also provides consulting services. Most sales come from customers in the Americas. Cisco's primary customers are large enterprises and telecommunications service providers, but it also sells products designed for small businesses.
