September 1972

Founder Douglas M. Curtiss founds Sonitrol Security Systems of Hartford, a commercial security company based out of Rocky Hill, CT.

We later merge with other local Sonitrol companies to become Sonitrol New England.


1970s – 1980s

Working closely with local police and fire departments, we make huge improvements aimed at reducing false alarms.

The authorities trust our alarm systems and verification process; that’s why when one of our alarms get off, emergency response times are significantly faster compared to many competitors.


1980s – 1990s

Business owners and longtime customers start asking us if they can put Sonitrol systems in their homes as well.

We expand our alarm systems and monitoring services across the state. Now, we’re protecting homeowners, school districts, and small businesses, too.


1990s – 2000s

We expand into other states in New England, acquiring residential alarm companies in Rhode Island (HB Alarm) and Massachusetts (Intercity Alarms).

Our residential security team is later rebranded as Alarm New England.



The Alarm New England team continues to add more offices around Massachusetts, setting up a team in the heart of downtown Boston.

This transition marks our shift towards professional-grade DIY home security systems, smart home automation, flexible installation options, and an end-to-end user experience that people trust.



Alarm New England continues to expand its range of products and services to make our communities safer places to live. We now protect over 27,000 of our fellow New England residents in Massachusetts, Connecticut, and Rhode Island.

Protection you can count on.

Sometimes, the simplest facts speak the loudest.

Our customers speak for us.

Generations of developing security expertise, building partnerships with the authorities, and listening to customer feedback have helped us find new ways to protect the local community.

You can feel confident that, with over four decades of experience,  Alarm New England will provide you with the highest level of protection and service.

Feel free to give us a call if you have any questions.

UL-Approved Monitoring

We will never outsource your safety. That’s why we own and operate our UL-approved monitoring station. It’s the nerve center of our operation and a cornerstone of keeping you safe 24/7.

Schools, government offices, and businesses large and small trust us to respond instantly in a crisis. We always deliver on that promise.

Superior, Local Service

We’ll get to know you – and that matters when you have questions about your system, need technical support, or we need to contact you to verify an alarm. We are always available.

We’ll never forward you to a giant call center across the ocean. Instead, you’ll hear a local and familiar voice you’ll recognize each time.

45 Years of Expertise

Security has been always been our business. We’re a close-knit, family-owned company nestled in the heart of New England.
We live here, we raise families here, and our children go to school here. This is our home.

Professional Support

Our trained technicians are professional, trusted, bonded employees – not contractors. They are trained, certified, and have undergone background checks.

That’s important when our customers let us into their home to do a professional installation and guide them through their system.
