Two-thirds of US-based security chiefs at large technology companies say the threat of violence towards their executives has increased in the past two years, with many now providing protection for senior staff and their families.
A survey of 2,352 security chiefs at large and medium-sized companies in 31 countries, conducted by US security and staffing company Allied Universal, found that businesses around the world have faced increasing threats of violence, with the US technology sector the worst affected.
Allied chief executive Steve Jones said measures to protect executives have increased dramatically since last year's high-profile killing of UnitedHealthcare boss Brian Thompson.
