Long Island covers the affluent Nassau and Suffolk suburbs east of New York City — a large, spread-out service area. Regional malls and retail, the Melville and Hauppauge corporate parks, the Northwell healthcare system, waterfront estates, event venues, and an active construction pipeline drive demand for retail loss prevention, corporate lobby posts, healthcare officers, estate and residential protection, and event security. Most contract security is unarmed, with mobile patrol widely used to cover the region's dispersed commercial and residential properties.
The providers below are ranked on merit, but the final check is yours. Work through these four steps before you sign anything in Long Island:
Private security in New York is licensed at the state level by the New York Department of State, Division of Licensing Services. A legitimate company operating in Long Island holds a Watch, Guard or Patrol Agency license, which means it has cleared NY DOS's ownership, background-check and insurance requirements. Ask for that license number in writing and verify it yourself — a certificate on the wall tells you nothing about current standing, since a license can be suspended or revoked.
Hiring an unlicensed company is a risk you carry. In New York, operating without a license is misdemeanor (class b) (General Business Law § 70-a(3) (Article 7)). Engaging in, or advertising as, a watch, guard or patrol agency without a DOS license is a class B misdemeanor per violation (up to 90 days jail and/or a fine up to $500); a business that hires an unlicensed agency faces no separate criminal charge but loses the surety-bond/insurance protection and DOS complaint recourse that Article 7 licensing provides.
