Cisco Systems is an American technology company specializing in computer network technologies and devices.
The company was founded by a then-married couple, Len Bosack and Sandy Lerner in 1984.  Both were computer science professors at Stanford University. At that time, Cisco was one of the two main challengers in the router market, the other being Wellfleet; Wellfleet's identity disappeared in a series of mergers and acquisitions, while Cisco became known for its acquisitions.
