Prominent Silicon Valley companies spend liberally to protect their intellectual property. Some also shell out considerable amounts to protect their executives. Apple’s most recent proxy statement, filed earlier this month, shows the company spent $310,000 on personal security for CEO Tim Cook. But that’s a fraction of other tech giants’ expenditures.

Amazon and Oracle spent about $1.6 million each in their most recent fiscal years to protect Jeff Bezos and Larry Ellison, respectively, according to documents filed with the US Securities and Exchange Commission. And Google's parent company, Alphabet, laid out more than $600,000 protecting CEO Sundar Pichai and almost $300,000 on security for former executive chair Eric Schmidt. In 2017, Intel spent $1.2 million to protect former CEO Brian Krzanich. Apple, Google, Intel, and Oracle declined to comment; Amazon did not respond to a request for comment.
