Welcome to
Atlantic Security Inc.
Electronic security for residential and commercial properties

As a Kent County, MD  based company providing security for home and business,  Atlantic Security Inc. is committed to our customers.  With everyone from big box stores to internet providers offering security solutions, it is difficult to know who to trust.  We are in our 48th year of serving our community, with thousands of satisfied customers, some of whom have been with us from the beginning.    Since our reputation is important to us, you know that you can trust us to protect what is important to you.

Residential and commercial security, life safety and camera systems

Our general service area providing security for home and business, includes Caroline, Cecil, Dorchester, Kent, Queen Anne, and Talbot counties in Maryland, as well as New Castle county in Delaware.

Other Maryland counties will be considered on a case by case basis. By keeping our service area small, we are able to give our customers exceptional  service.  We know that when you call for service, you expect to receive it in a timely fashion, and we strive to respond as quickly as possible.

When you call our office during business hours, you will speak to real people. We don’t give you the automated runaround.  If, for some reason we are unable to answer your call, your call will be returned as soon as we are able to do so.   We will work with you to find the system that is best for you,  addressing your needs and concerns.

Unlike some larger companies, we will never ask for a credit card to give you an estimate.  Your first payment to us will be a deposit on a proposal accepted and signed by you. There will be no hidden charges or fees.
