Cisco Systems, Inc. (using the trademark Cisco) is an American multinational digital communications technology conglomerate corporation headquartered in San Jose, California. Cisco develops, manufactures, and sells networking hardware, software, telecommunications equipment and other high-technology services and products.[4] Cisco specializes in specific tech markets, such as the Internet of things (IoT), domain security, videoconferencing, and energy management with products including Webex, OpenDNS, Jabber, Duo Security, Silicon One, and Jasper.
Cisco Systems was founded in December 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists who had been instrumental in connecting computers at Stanford. They pioneered the concept of a local area network (LAN) being used to connect distant computers over a multiprotocol router system. The company went public in 1990 and, by the end of the dot-com bubble in 2000, had a market capitalization of $500 billion, surpassing Microsoft as the world's most valuable company.[5][6]
Cisco stock (CSCO), trading on Nasdaq since 1990, was added to the Dow Jones Industrial Average on June 8, 2009, and is also included in the S&P 500, Nasdaq-100, and the Russell 1000 indices.[7][8]
