Barracuda Networks

BJ Jenkins, President, CEO

Headquarters: Campbell, Calif.

Barracuda was acquired by private equity firm Thoma Bravo for $1.6 billion due to the company's ability to bring comprehensive offerings to customers in an increasingly hostile and complex threat environment. The company also in recent months bought public cloud information archiving and analytics firm Sonian, as well as social engineering simulation and training platform player PhishLine.
