High paying security and protective service jobs in Rockford, IL

Every security and protective service occupation below is ranked by its median annual wage in Rockford, IL. Read the percentile range, not just the median: the gap between the 10th and 90th inside a single security and protective service job is usually wider than the gap between two different ones, so where you land in a field matters more than which field you pick.

Cost of living: prices in Rockford, IL run 7.8% below the national average (2024), so a Rockford, IL salary is worth about 1.09× its face value in national terms. That scales every wage here by the same factor — it changes what the numbers mean, not their order.

Local wage estimates are suppressed more often than state ones — BLS withholds any figure too few local employers report — so an occupation missing here simply has no published local estimate.
