Our Story

Since our humble beginnings in Greenport,1989 we have been serving the East End of Long Island with professional security and fire alarm services for local homes and businesses. Respected as an industry leader by our peers as well as the manufacturers we partner with, Suffolk Security Systems brings new and proven technology to help protect you, your family and assets.

We volunteer our time and our donations to dozens of local organizations, helping to improve lives and keep our community safe.

We are locally owned and not part of an "out-of-touch" franchise operation. That means we know our clients, understand their needs and accommodate them better than those "big box" or DIY companies. We are an active member of the Long Island Alarm Association, the Electronic Security Association and the National Fire Prevention Association. 

Suffolk Security Systems is licensed by both the New York State Department of State and the Suffolk County Department of Consumer Affairs.

We work proactively with local fire and police departments to promote the responsible use of alarm systems thus reducing false dispatches that waste valuable local emergency resources.
