The Department of Homeland Security is in place to try and protect the US and employs almost a quarter of a million people.

Included in its subsidiaries are the U.S. Customs & Border Protection, the Secret Service, Office of Intelligence & Analysis and many more. 

The department says: “The Department of Homeland Security has a vital mission: to secure the nation from the many threats we face. This requires the dedication of more than 240,000 employees in jobs that range from aviation and border security to emergency response, from cybersecurity analyst to chemical facility inspector. Our duties are wide-ranging, and our goal is clear – keeping America safe.”
