How Technology, Collaboration and Public-Private Partnerships Are Transforming Urban Security When Maria Sumnicht arrived at the newly formed New York City Cyber Command in 2018, she inherited a problem nobody could fully describe. City agencies, more than 60 of them, had spent years connecting sensors, cameras, transponders, and access points to municipal networks with little coordination and less oversight. Nobody knew how many devices were out there. Nobody knew who had installed them, whether they were still supported, or whether they had ever been tested for basic security flaws. "It was the wild, wild west," Sumnicht said. "Everyone was just bringing in whatever they needed, putting it on their networks, and really not thinking about the cyber hygiene behind the solution." What Sumnicht and her team built from that starting point, a proactive endpoint security program that would go on to uncover 159 previously unknown vulnerabilities, offers a blueprint for how American cities are rethinking what it means to be smart. The lesson isn't just about better sensors or faster analytics. It's about resilience, and about who cities trust to help build it. From Connected to Resilient For most of the past decade, the smart city conversation centered on connectivity and efficiency: traffic sensors, digital kiosks, cashless parking. That conversation has shifted. Cities today are contending with violent crime, cyberattacks on critical infrastructure, severe weather, civil unrest and geopolitical instability, often at the same time. Technology alone can't solve that. What's emerging instead is a model some in the industry call Safe Cities 2.0, where public agencies, private security leaders, utilities, transportation authorities and technology providers share data and coordinate response rather than operating in isolation. The trajectory is fairly clear: Smart City 1.0 was about efficiency and automation. Smart City 2.0, where most major cities sit today, is about
