Star’s Net Worth: $100 billion*
Annual Protection Cost: $23 million*

Another controversial billionaire is Facebook CEO Mark Zuckerberg. According to estimates, the tech mogul spent $23 million in security in just one year. Though this is mere pocket change for the billionaire, Facebook footed the bill for the security costs, which have only increased as time has gone on.

In 2017, Facebook spent $9.1 million, and in 2018, the company spent $20 million on security. The $23 million in 2019 represents another increase in a trend that is likely to continue. The Silicon Valley magnate reportedly pays for around-the-clock protection for him and his family, and, reportedly, his office has an escape room installed.
