Chicago is the Midwest's largest security market. The downtown Loop concentrates corporate towers, financial institutions, and hotels that contract standing guards and lobby security, while the South and West Sides host extensive industrial, rail, and warehouse facilities that rely on site guards and patrols. Event security for festivals, stadiums, and convention traffic at McCormick Place rounds out one of the deepest talent and supply pools in the country.

What's the risk of hiring an unlicensed security company in Chicago?
If an incident occurs involving personnel from an unlicensed company, you can face negligent-hiring liability. Unlicensed operators also frequently lack certified training, guard registration (guard cards) and active liability insurance, and states can fine businesses that knowingly use them. Always verify the state license before signing a contract.
