Long Island Security Guard Company

On-site security services for Nassau and Suffolk counties, tailored to the needs of office parks, healthcare campuses, and industrial facilities.

Security Guarding Services for Long Island Businesses

Prosegur Security is a licensed Long Island security guard company serving commercial clients throughout Nassau and Suffolk County. Our branch operates from Melville on the Route 110 corridor, and officers are registered with the New York State Department of State and scheduled and supervised from this office. Long Island security services include on-site security guards, lobby and concierge coverage, remote video monitoring, integrated access control and surveillance systems, 24/7 emergency response, and enterprise cybersecurity.

 

Long Island runs on a set of distinct corridors rather than a single downtown, and a program has to be built around whichever one you sit in. Office parks along Route 110 through Melville, Plainview, and Farmingdale need lobby presence and visitor management. Hauppauge Industrial Park, the largest of its kind in the Northeast, runs on dock and yard coverage instead. Healthcare campuses across Nassau operate around the clock with their own credentialing requirements, and the East End reverses everything seasonally, where hospitality and vineyard properties need coverage that triples between Memorial Day and Labor Day. Many sites pair a lean on-site presence with remote monitoring to hold parking fields, loading docks, and after-hours perimeters without a post at every entrance.

 

Our Long Island security team serves Nassau and Suffolk County, including Melville, Hauppauge, Plainview, Farmingdale, Bethpage, Syosset, Woodbury, Hicksville, Westbury, Garden City, Mineola, Uniondale, Great Neck, Huntington, Smithtown, Ronkonkoma, Islip, Bay Shore, Riverhead, and the Hamptons.

Long Island Security Services FAQ | Nassau & Suffolk County
What types of commercial security guard services does Prosegur offer on Long Island?

Prosegur provides a full range of commercial security guard services for businesses across Nassau and Suffolk County, including Melville, Hauppauge, Garden City, Hicksville, Huntington, Farmingdale, Islip, Westbury, and the East End. Our offerings include uniformed officers, lobby and concierge security, access control management, event security, remote monitoring, and technology integration built around the needs of Long Island properties.

Why choose Prosegur over other security guard companies on Long Island?

Long Island businesses choose Prosegur for our local supervision, experienced officers, and ability to combine physical and digital security in one program. Officers are scheduled and supervised from our Melville office on the Route 110 corridor, licensed in New York State, and backed by remote monitoring technology, which means broader coverage of your site and proactive response rather than reactive reporting.

What is Remote Security Monitoring and how does it work for Long Island businesses?

Remote Security Monitoring combines live video surveillance, real-time alerts, and two-way audio managed by trained agents in our Security Operations Center. It allows Long Island businesses to detect, deter, and respond to activity as it happens, extending coverage across large or unstaffed areas such as parking fields, loading docks, storage yards, and after-hours perimeters.

Can I use both Remote Monitoring and on-site guards at my property in Nassau or Suffolk County?

Yes. Our hybrid security model is a strong fit for Long Island sites that need presence at the door and visibility everywhere else. Pairing on-site officers with remote video monitoring keeps access points controlled while cameras cover the rest of the property, which works well for office parks along the Route 110 corridor, Hauppauge Industrial Park facilities, distribution centers, retail centers, and multi-site portfolios.

Are Prosegur's security guards licensed and trained in New York State?

Yes. All Prosegur security personnel on Long Island are registered with the New York State Department of State and comply with state and local requirements, including pre-assignment training, on-the-job training, and annual in-service instruction. Officers are trained in emergency procedures, access control, surveillance, report writing, customer service, and de-escalation techniques.

How fast can Prosegur deploy security guards on Long Island?

With local staffing and supervision in place, we can typically deploy licensed security professionals within 24 to 72 hours. We support both urgent and scheduled coverage in Melville, Hauppauge, Plainview, Farmingdale, Mineola, Garden City, Uniondale, Huntington, Smithtown, Ronkonkoma, Islip, Riverhead, and surrounding communities in Nassau and Suffolk County.

Which industries does Prosegur protect on Long Island?

We work with hospitals, health systems, and medical office buildings, senior living and skilled nursing facilities, biotech and life sciences campuses, aerospace, defense, and precision manufacturing, corporate offices and business parks, warehouses and last-mile logistics, construction sites and contractor yards, retail centers and auto dealerships, utilities and offshore wind infrastructure, marinas and waterfront properties, schools and research institutions, and East End hospitality and vineyard properties. Each program is scoped to the site, the hours it operates, and the risks specific to its location.

Can Prosegur provide coverage during storms, holidays, and seasonal peaks?

Yes. We plan for the conditions Long Island sites actually face, from nor'easters and coastal storm season to holiday retail traffic and the summer surge on the East End. Coverage can scale up for seasonal demand, extend to storm standby and post-event property checks, and hold through weekends and holidays without gaps in reporting.
