Dahlcore Security Guard Services provides licensed armed and unarmed security officers across Brooklyn, New York — every neighborhood, from Williamsburg, Greenpoint, and Bushwick in the north to Bay Ridge, Bensonhurst, and Sunset Park in the south, with Crown Heights, Park Slope, Bed-Stuy, and DUMBO in between. We serve Brooklyn from our Staten Island headquarters and Manhattan office, with rapid dispatch and site-specific post orders for residential buildings, commercial properties, construction sites, retail, and events. Founded in 2018 and led by Ian Dahlberg, who brings over 23 years of security experience, our veteran-owned team gives Brooklyn property managers, business owners, and event organizers a professional, accountable security presence — not a generic post from a distant call center.
Security Guard Services Across Brooklyn
Brooklyn’s security needs change block by block — a luxury tower in DUMBO carries different risks than a retail corridor in Flatbush or a construction site in Greenpoint. Dahlcore builds each plan around the specific property, schedule, and risk profile, with written post orders before the first shift, so coverage fits your site rather than a one-size-fits-all package.

A real team, a real point of contact
Dahlcore serves Brooklyn from our Staten Island headquarters and Manhattan office, with officers who know the borough. You reach a real person who manages the account directly — a named account manager, written post orders, and supervisor oversight behind every shift — not a rotating roster and a national queue.
Why Brooklyn Clients Choose Dahlcore
Licensed, accountable, and built around your property — Dahlcore protects Brooklyn buildings, businesses, sites, 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, and to a professional demeanor on every Brooklyn post.
Trained & Technology-Supported
Officers complete New York’s required training (8-hour pre-assignment, 16-hour on-the-job, and 8-hour annual in-service through DCJS-approved programs), with up-to-date certifications and de-escalation training. GPS-tracked patrol tours and a real-time incident-reporting app give you a timestamped log of every checkpoint and action.
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 — so you are informed, not left to discover problems yourself.

Brooklyn Security FAQ
Clear answers for Brooklyn property managers, business owners, and event organizers. For anything not covered here, call 212-208-0900.
Do you provide security guards in Brooklyn?
Yes. Dahlcore Security Guard Services provides licensed armed and unarmed officers across all of Brooklyn — North, Downtown, Central, South, East, and Northwest Brooklyn — for residential buildings, commercial properties, construction sites, retail, and events. Request a free site assessment or call 212-208-0900.
What Brooklyn neighborhoods do you cover?
All of them — including Williamsburg, Greenpoint, and Bushwick in the north; DUMBO, Brooklyn Heights, and Red Hook downtown; Crown Heights, Park Slope, and Flatbush in Central Brooklyn; Bay Ridge, Bensonhurst, and Sunset Park in the south; Brownsville, East New York, and Canarsie in the east; and Fort Greene, Clinton Hill, and Bed-Stuy in the northwest.
Do you have a Brooklyn office?
Dahlcore serves Brooklyn from our Staten Island headquarters (1110 South Avenue) and our Manhattan office (250 Park Avenue), with Brooklyn-area officers and 24/7 dispatch. You get local coverage and a named account contact without a middleman call center — and management you can actually reach.
Are your Brooklyn 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 Brooklyn?
Both. Unarmed officers suit most residential, retail, office, and event assignments and are trained in de-escalation, access control, and incident documentation. Armed officers are recommended for higher-risk commercial locations, cannabis dispensaries, and sites needing a stronger deterrent; they are licensed under New York’s pistol-license law (Penal Law §400) and complete annual firearms qualification. We advise on the right model at no charge during the initial consultation.
Can Dahlcore staff one-night or short-term events in Brooklyn?
Yes. Dahlcore staffs single-event and short-term assignments — private events, corporate functions, film productions, and pop-up retail — with crowd management, access-point control, and vendor credentialing. Contact us with your event details to scope coverage.
Do you offer bilingual security officers in Brooklyn?
We can often accommodate language requests for Brooklyn assignments. Let us know the language you need during your consultation and we will confirm availability for your site.
How quickly can you start coverage in Brooklyn?
After a site assessment and post-order confirmation, coverage can begin quickly, subject to officer availability and site complexity. For urgent needs and coverage gaps, Dahlcore prioritizes rapid dispatch across the borough — call 212-208-0900 and our 24/7 dispatch will discuss your timeline.
