Intel has been trying to make its workforce more diverse.

However CEO Brian Kzranich says he and his top execs had received threats “around our position on diversity and inclusion.”

Intel says it is “determined to enhance the personal security for CEO and certain other listed officers in response to specific Intel-related incidents and threats against those officers and, in some cases, members of their families.”

Last year Intel spent more than $2 million on Krzanich’s security up from less than $40,000 in 2015.

The $2 million includes $1.86 million for personal security and $275,200 for security for Kzranich’s house.

Other execs’ security costs were $944,800 for Venkata Renduchintala and $309,900 for Stacy Smith.
