Dahlcore Security Guard Services provides licensed armed and unarmed security officers across New York State. Headquartered in New York City — with offices in Staten Island and Manhattan — we serve all five boroughs, Long Island, and communities across New York, delivering one consistent, accountable security program wherever your properties are. For businesses with multiple sites, or assignments beyond the five boroughs, Dahlcore coordinates statewide coverage under a single point of contact, with site-specific post orders and 24/7 dispatch. Founded in 2018 and led by Ian Dahlberg, who brings over 23 years of security experience, our veteran-owned team gives New York property managers, facility directors, and multi-location businesses a security partner that scales with them across the state.
Security Guard Services Across New York State
Dahlcore’s home is New York City — the five boroughs and Long Island are our operational core — and from there we serve organizations across New York State. Whether you run a single property or a portfolio of sites in different regions, you get the same standards, the same licensing, and the same reporting on every post, coordinated through one account team rather than a patchwork of local vendors.
How Our New York Coverage Works
- New York City & Long Island — full local coverage across Manhattan, Brooklyn, Queens, the Bronx, and Staten Island, plus Nassau and Suffolk Counties, run from our Staten Island headquarters and Manhattan office
- Statewide & regional reach — for sites and assignments beyond the metro, Dahlcore deploys and coordinates coverage across New York, including Westchester, the Hudson Valley, and other New York communities
- Multi-site programs — one security plan, one account manager, and consistent post orders and reporting across every New York location in your portfolio
- Corporate & portfolio clients — standardized coverage for property managers, corporate real estate, and businesses operating in more than one New York market
One standard, every location
Managing security across several New York properties shouldn’t mean juggling a different vendor, contact, and reporting format for each one. Dahlcore gives multi-site clients a single account team, consistent written post orders, and unified reporting across every location — so a portfolio in New York City, Long Island, and beyond runs to one standard, with one number to call.
Why New York Businesses Choose Dahlcore
Licensed, accountable, and consistent from one site to a statewide portfolio — Dahlcore protects New York businesses, buildings, and events.
Licensed & Background-Checked
Dahlcore is a licensed New York security guard agency (NY Department of State). Every officer is registered under New York’s Security Guard Act (General Business Law Article 7-A) with the NY Department of State’s Division of Licensing Services (NYSDOLS), thoroughly background-checked, and trained through DCJS-approved programs. Dahlcore is fully insured; certificates of insurance and credentials are available on request.
Veteran-Owned & Owner-Managed
Dahlcore is veteran-owned and operated — founded in 2018 and led by Ian Dahlberg, who brings over 23 years of security experience. The owner personally manages guards in the office and in the field, and officers are held to law-enforcement and military standards across every New York post.
Consistent Across Every Site
Whether you have one property or a statewide portfolio, Dahlcore applies the same training standards, written post orders, and reporting to every location — coordinated by a single account team, so multi-site programs stay consistent instead of fragmenting across vendors.
Documented & Accountable
Every account has a named account manager, written post orders, and regular supervisor check-ins. Each shift produces a daily activity report, and any incident is captured in a documented report suitable for your records and any law-enforcement follow-up — with GPS-verified patrol tours and real-time reporting.

New York Security FAQ
Clear answers for New York property managers, facility directors, and multi-location businesses. For anything not covered here, call 212-208-0900.
Does Dahlcore provide security guard services across New York State?
Yes. Dahlcore is headquartered in New York City — with offices in Staten Island and Manhattan — and serves the five boroughs, Long Island, and communities across New York State. For sites beyond the metro or multi-region portfolios, Dahlcore coordinates statewide coverage through one account team. Call 212-208-0900 to confirm coverage for your location.
Can Dahlcore manage security across multiple New York locations?
Yes. Multi-site programs are a core strength: you get one security plan, one named account manager, and consistent post orders and reporting across every New York location in your portfolio — instead of managing a different vendor and reporting format at each site.
Where are Dahlcore’s offices?
Dahlcore operates from two New York offices — our headquarters at 1110 South Avenue, Staten Island, and our Manhattan office at 250 Park Avenue — with guard dispatch and supervision operating 24/7 across every New York account.
Are Dahlcore’s guards licensed in New York State?
Yes. Dahlcore is a licensed New York security guard agency (NY Department of State), and every officer holds a valid New York State security guard registration under the Security Guard Act (General Business Law Article 7-A), issued through the NY Department of State’s Division of Licensing Services (NYSDOLS). Officers complete NYS-mandated training — 8-hour pre-assignment, 16 hours on-the-job, and 8 hours annual in-service — through DCJS-approved programs. You can verify any New York security registration through the NY Department of State’s public license lookup at dos.ny.gov.
Do you provide armed or unarmed guards in New York?
Both. Unarmed officers suit most assignments and are trained in de-escalation, access control, and incident documentation. Armed officers are matched to higher-risk sites; they are licensed under New York’s pistol-license law (Penal Law §400) and complete annual firearms qualification. We advise on the right model during the initial consultation.
Which New York areas does Dahlcore cover in depth?
Our local teams cover New York City — Manhattan, Brooklyn, Queens, the Bronx, and Staten Island — and Long Island (Nassau and Suffolk Counties) in depth, each with a dedicated local page. For other New York communities and multi-site programs, Dahlcore coordinates and deploys coverage; call to confirm your specific location.
How quickly can Dahlcore start coverage in New York?
After an assessment and post-order confirmation, coverage can begin quickly, subject to officer availability, location, and site complexity. For urgent needs and coverage gaps, Dahlcore prioritizes rapid dispatch — call 212-208-0900 and our 24/7 team will discuss your timeline.
