How many state licensed security companies are there in Denver?
In Denver, Colorado we list 119 private security companies with an active state license in our directory. All of them have a license number you can verify on the state licensing board's public lookup.
How do I verify that a company in Denver is really licensed?
Every company in this listing shows its license number. Cross-check it directly on the authority the company is registered with — Colorado has no single statewide security registry (your city's licensing office (for example, Denver Excise & Licenses)). If the number doesn't come up, or the status shows "expired", "suspended" or "revoked", don't hire that company — you could face negligent-hiring liability if an incident occurs.
What does it mean for a company to be "state licensed"?
Colorado does not license security companies through a single statewide registry — authorization runs through city and county governments — Colorado has no statewide security regulator. A licensed company holds an active license, employs registered and trained officers, carries the required insurance and meets its tax and labor obligations.
What services do state licensed companies in Denver offer?
State licensed companies in Denver offer security guards, armed security, mobile patrol, event security, executive protection, alarm monitoring, video surveillance and security consulting. Each profile details the specific services each provider offers.
What's the risk of hiring an unlicensed company in Denver?
If an incident occurs involving personnel from an unlicensed company, you can face negligent-hiring liability. Unlicensed personnel may also lack certified training, guard registration or active liability insurance. State regulators can fine both the operator and the business that hires them.
How often does a state security license renew?
In Colorado, licenses renew on the schedule the licensing city sets (Denver renews annually). Companies must keep insurance and training requirements current to stay licensed, so check the issue date and not just the status. Each company's current license status appears on its HireSecurityNow.com profile.
