Matthew Prince, chief executive at an internet start-up company called CloudFlare, poses in his office in San Francisco December 10, 2012. Founded in 2010, CloudFlare markets itself as an Internet intermediary that shields websites from distributed denial-of-service, or DDoS, attacks, the crude but effective weapon that hackers use to bludgeon websites until they go dark. The 40-person company claims to route up to 5 percent of all Internet traffic through its global network. REUTERS/Gerry Shih
