Although many buy-ins (such as Crescendo Networks in 1993, Tandberg in 2010) resulted in acquisition of flagship technology to Cisco, many others have failed—partially or completely. For instance, in 2010 Cisco occupied a meaningful share of the packet-optical market, revenues were still not on par with US$7 billion price tag paid in 1999 for Cerent. Some of acquired technologies (such as Flip from Pure Digital) saw their product lines terminated.
In January 2013, Cisco Systems acquired Israeli software maker Intucell for around $475 million in cash, a move to expand its mobile network management offerings.. In the same month, Cisco Systems acquired Cognitive Security, a company focused on Cyber Threat Protection. Cisco also acquired SolveDirect(Cloud Services) in March 2013 and Ubiquisys(Modile Software) in April 2013.

Flip Video
With the acquisition of Pure Digital Technologies, Cisco began to sell a line of video recording devices called "Flip Video" that had been Pure Digital's only line of products. This line of products was not as popular as Cisco had thought it would have been, and on April 12, 2011, Cisco announced they were discontinuing all Flip camera production. Cisco ūmi product line—video conferencing for home also proved to be a short-lived bid for consumer multimedia market and did survive in Cisco product lineup.
