If you’ve got a business, you need someone responsible for its physical and data security. If the business is large enough, that would be a Chief Security Officer, or CSO.
Aspects of a CSO’s job are discussed in a Security Infowatch post.
“Companies need to plan for all conceivable man-made and natural occurrences, ranging from hurricanes to network malware attacks. Calling a contract security company for help in the middle of Hurricane Harvey, for example, will not be fruitful.” Or in the midst of any other security challenge, either.
