Frequently asked questions

Do security guards in Janesville need a state license?

Yes. Security in Wisconsin is regulated by the Department of Safety and Professional Services (DSPS), not the city. The agency must hold a Private Detective/Security Agency credential (DSPS credential type 62, which covers both guard and detective agencies), and each officer must hold an individual Private Security Person permit. There's no separate local Janesville license. Given the volume of distribution and logistics work here, confirm the provider's DSPS agency credential, its individual guard permits, and its insurance on the DSPS online license lookup before committing.

Why is warehouse and distribution security a core service in Janesville?

Janesville anchors Rock County along the I-90/I-39 corridor between Madison and the Illinois line, with a large logistics footprint. Distribution centers and warehousing drive heavy demand for warehouse and site guards, gate and dock access control, overnight yard patrol, and cargo-theft prevention — with risk concentrating after hours. Manufacturing plants add industrial coverage, regional healthcare needs de-escalation-trained officers, and the Milton Avenue retail corridor sustains loss-prevention work. Beloit and the Walworth County communities contribute further logistics and commercial demand. A provider with real supply-chain experience is essential for the warehouse sites.
