About Us: Professional Security and Protection Services in NH for over forty years.

Northeast Security Agency was established in 1983 as a security officer and security patrol service offering security personnel to the businesses and residents of New Hampshire. 

Our commitment to superior service and customer satisfaction has been priority #1 since day one. Over the years, we have grown and expanded our services primarily through word-of-mouth advertising. We maintain that this type of advertising based on our customer's experiences with us is the best form of advertising possible. Therefore spending more time and money to keep our customers happy is time and money well spent.
