Armed security guards on Long Island.
Armed security on Long Island is a New York armed-guard post for a house, a business, or a private school in the Long Island area Tristate lists, with Nassau County as the county this page can describe. Call 347-991-0121. There is no Long Island office. The address is 5314 16th Avenue, Suite 238, Brooklyn, NY 11204.
People also search for armed guards for Long Island schools. That request is handled as a school post that happens to be armed, not as a different license.
For most standard posts, uniformed officers are scheduled within 24–48 hours. Emergency coverage is coordinated through 24/7 dispatch.
Campuses, houses, and stores on larger lots.
A Long Island armed post is often a school driveway at arrival, a residence set back from the road, or a store with a parking field. The officer needs to know whether they are at the lobby, the lot, or with a person. Those are three different orders.
Unarmed coverage is still available and is often the right call for a house that really wanted a marked car. Armed is for the posts that have decided a firearm is part of the job.
Private schools
Arrival, dismissal, and events when the school asks for an armed officer.
Residences
A defined post at a house, not a roaming armed patrol of a village.
Businesses
Retail and commercial doors in Nassau communities on the coverage footprint.
New York credentials
Pistol license, 47-hour course, and armed registration. Not a New Jersey card.
Nassau searches, without a fake town-by-town roster.
“Armed security Nassau County” and “armed guards Long Island schools” are specific requests. This page answers them with New York law and with the school-security service. It does not list villages where an armed officer is supposedly already assigned. If your school or house is in a named town, put the town in the quote.
Travel from Brooklyn is part of the schedule. Most standard posts are placed within 24–48 hours when an armed officer who can make that trip is free. That sentence is not a response time from the nearest parkway exit.
Long Island uses New York armed-guard law.
DCJS and the Department of State require a New York pistol license, the 47-hour firearms course, and a special armed registration, plus annual armed in-service training. A retired officer’s status does not skip those steps unless a DCJS waiver actually applies to that person. The company does not promise that every armed officer is a retiree.
Schools decide whether they want an armed post. This page does not claim that New York law requires armed security at private schools. It says the company can staff that request when the school wants it and the officer is qualified.
Licensed officers, documented work.
Founded in 2021. Brooklyn address. Long Island armed work is scheduled from that company under New York licensing.
No school district is named. No crime statistic for any town is cited, because this site is not publishing one.
What is published, and what is quoted.
Armed Long Island posts, including schools, are quoted. Community Watch memberships are New York City only, so a house that wants checks instead of an armed officer is quoted on its own.
Answers, in plain language.
Do you provide armed security on Long Island?
Yes, for properties in the Long Island area the company lists. Call 347-991-0121. Officers need New York armed-guard credentials.
Can you staff armed guards at a Long Island school?
Private schools can request it. The officer still needs the New York armed registration. See the school security page for what the day looks like.
Is Nassau County included?
Yes. Nassau is the county this Long Island page describes. Name the town on the quote.
How much do armed guards cost on Long Island?
The rate is quoted. It is not the monthly patrol price.
Do New Jersey armed rules apply?
No. Long Island is New York. New Jersey SORA is a different page and a different credential.
