The Connextivity Advantage

Your Trusted New York City Security Assessment Experts

Government-Proven Methodology

We apply the same structured assessment process used for U.S. military installations and federal facilities to residential and commercial properties across New York City.

Objective & Unbiased Recommendations

Because the assessment is separate from installation, our findings are completely objective. We identify real vulnerabilities, not products to sell.

CPP/CSPM Certified Professionals

Assessments are conducted by certified security professionals with 7+ years of industry experience — not sales representatives.

New York City Property Expertise

We understand New York City’s layout, waterfront exposure, commuter hubs, and neighborhood-specific risks.

Trusted by Property Owners,

Developers, and Businesses

  • "The views were crystal clear and a big improvement over the 15 year old cameras. The Commander was very complimentary of the team's performance and professionalism."

    Confidential Government Client, International Acquisions

  • "We greatly appreciate the project coming in within the budget parameters and in a highly timely manner. The system selected was exceedingly easy to train on and has proven to be easy to use. We greatly appreciate Connextivity's significant knowledge of security systems and selecting a system that exceeded our expectations."

    Private Community Trustees

  • "It has been a pleasure working with Connextivity and I truly appreciate all the work you have done for our squadron. Your professionalism and efficiency were much appreciated. I know you will continue to provide the same level of service through the years to come."

    Chief, Air Transportation Resources, Confidential Military Base

  • "The system selected and installed fully meets the needs, has vastly improved the level of security, and has provided an increased level of peace of mind."

    Confidential Development Management

  • "With the previous national company, our monitoring rates kept increasing, while our false alarms became more frequent. We would often get woken up in the middle of the night... Their customer service could never answer questions about the system. They would charge us exorbitant service call fees just for a battery change for a temporary fix. There were so many false alarms that we received a subpoena from the city. We had to leave the system disarmed. Connextivity's system has been very reliable and easy to use via the touchscreen and app, and they are quick to answer our questions.”

  • Protecting a construction site near Hudson Yards

  • Managing multi-family access control in a Brooklyn brownstone
