Austrian-born Gerhard Eschelbeck has ranged the British city of Oxford; cavorted at notorious Def Con hacker conclaves, wrangled a herd of startups, and camped out in Silicon Valley.
He now holds the reins of security and privacy for all-things Google.
In an exclusive interview with AFP, Eschelbeck spoke of using Google's massive scope to protect users from cyber villains such as spammers and state-sponsored spies.
"The size of our computing infrastructure allows us to process, analyze, and research the changing threat landscape and look ahead to predict what is coming," Eschelbeck said during his first one-on-one press interview in his new post.
