9. Cisco Buys SD-WAN Startup Viptela
Price: $610 million
Cisco got serious about SD-WAN in May when it announced plans to acquire SD-WAN specialist Viptela for $610 million in cash and equity. The deal bolstered Cisco's existing portfolio of SD-WAN solutions, including its iWAN and Cisco Meraki offerings. Cisco closed its acquisition of Viptela on August 1.
In a similar deal, Vmware revealed its plans to acquire SD-WAN startup VeloCloud in November for an undisclosed amount.
