Had an existing system in the house and my first indication of their honesty and professionalism is that they didn't try to upsell me on a whole new system. Arthur installed the one item I needed and made sure everything worked and that the app was up and running before he left. Was on time, professional, knowledgeable. And any time I called the office I got a quick response. Would definitely recommend All Island to anyone in need of an alarm company.

We just had a situation arise where our alarm system went down. As we have done for years, we called All Island Security. They have been there for us since we had our first house in Nassau County to our current home in Suffolk County.over 20 years! As always, they were extremely responsive and arrived the same day to fix the issue. From the courteous staff answering the phones and scheduling the appointments to the very knowledgeable technician that came to our house, All Island Security is reliable, dependable and consistent.

Arthur and Dwayne were amazing. We recently moved into a new home and these guys took care of everything alarm related. I called several alarm monitoring services and All Island was the most reasonable and responsive. I would highly recommend to anyone in need of security services!

Very reliable company And competitively priced. Would highly recommend this company to anyone. Arthur the service mechanic was excellent and took his time to go over everything. Didn't feel rushed. If I could give them 6 stars I would!

I love using local companies. All Island is one of them. Hired them to take over the existing system after moving into the new house. Very reasonable pricing, no pressure sale. The guys really know the stuff and they are all long time employees and very knowledgeable and always nice to talk to. They use a local central station and the response time is great and the fee is very reasonable. Highly recommended.

All Island Security has managed our security system for about 5 years now. The service has been great. It is comforting to know someone is always monitoring our business location in off hours. The customer support has always been awesome I always recommend this company for home and business security. Keep up the great work!

All Island Security has been our alarm carrier for over 15 years. 10 years in one house and over 5 years in our current house. Extremely reliable and friendly customer service and service calls! For 15 plus years we have always encountered the same customer service reps. They are always eager to trouble shoot the problem over the phone before a service call is needed.

There has been the same technician for 15 years serving our systems. He is always polite and friendly! We highly recommend All Island for all of your home security needs! Wouldn't trust any other alarm company to protect our home and family!

All Island Security's central monitoring is excellent. I have had them for about 12 years now and every single time the alarm goes off (open window by mistake or something like that) they call almost immediately, I'd say within about 30 seconds and they are courteous and professional. Their monthly fees are very reasonable and I have had only a single repair (battery replacement) since they installed the system, Would definitely recommend them.

The first thing my fiancee and I did after purchasing our new home was solicit quotes for alarm services. All Island Security was the third or fourth company on our list. We reached out, scheduled an appointment and the Sales Rep showed. He was on time, friendly, professional and not pushy. The few companies we saw before All Island Security insisted on selling us everything but the kitchen sink.

All Island Security was the opposite; they listened to our concerns and recommended a system that we can add to if needed in the future. We were so happy with the service that we recommended All Island Security to my parents and my aunt.
