119 security guard and private security companies in Colorado, built from official state licensing data. Compare by city and request free quotes.
Colorado has no single statewide security-guard license; regulation is largely local — the City and County of Denver, for example, licenses security guards and their employers. Demand centers on Denver's downtown and LoDo entertainment district, a large cannabis industry with cash-handling needs, major sports and event venues, and expanding logistics along the I-70 and I-25 corridors.
