A New York State Licensed Agency on Long Island
On Demand Security Services holds New York State Watch Guard Agency and Private Investigation licenses, and we cover clients across Long Island in both Nassau and Suffolk counties. Whether you manage a shopping center, an office building, an apartment complex or a single storefront, we plan coverage around your property, your hours and the risks you actually face.
Patrols for Residential Communities, Malls and Parking Lots
Large, spread-out properties benefit from officers who move. Our patrol officers cover apartment complexes, malls and parking lots, and our residential security service combines armed or unarmed officers and mobile patrols with technology such as CCTV monitoring — a flexible approach focused on keeping residents and property safe.

Retail and Shopping Center Security
For stores, boutiques, supermarkets and shopping complexes we address shoplifting, theft, vandalism, stock damage and anti-social behavior. Our loss prevention agents complete a retail loss prevention training program, are certified undercover store detectives, and are trained at each client location so they understand its layout and regional requirements.
One Partner Across the Region
Many Long Island clients also operate in New York City, Westchester or New Jersey, where we are a licensed security agency. Working with one company means consistent standards and a single point of contact at every location.
