State Licensed Security Companies in Brooklyn

In Brooklyn, New York we list 249 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.

Every company in this listing shows its license number. You can cross-check it directly on your state licensing board's public lookup — BSIS in California or IDFPR in Illinois. 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.

Private security is regulated at the state level. In California, the Bureau of Security and Investigative Services (BSIS) licenses Private Patrol Operators; in Illinois, the Department of Financial and Professional Regulation (IDFPR) licenses private security contractor agencies. A licensed company holds an active license, employs registered and trained officers, carries the required insurance and meets its tax and labor obligations.

State licensed companies in Brooklyn 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.

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.

It depends on the state — California BSIS Private Patrol Operator licenses renew every two years, and Illinois IDFPR agency licenses on the board's set schedule. Companies must keep insurance and training requirements current to stay licensed. Each company's current license status appears on its HireSecurityNow.com profile.
