About The Company
Most security programs are built to check boxes. We’re built to stop what actually matters. Binary Defense is a Managed Detection and Response provider focused on one thing: helping organizations respond to real threats with speed, clarity, and confidence. Not theoretical coverage. Not inflated metrics. Real outcomes. We start with how adversaries actually operate inside environments. Then we build detection, investigation, and response around that reality. Because when seconds matter, assumptions break. At the center of our approach is NightBeacon, our AI-powered intelligence infrastructure embedded directly into the SOC. It accelerates analysis, surfaces what matters, and helps our analysts move at the pace modern threats demand. Not by replacing human expertise, but by strengthening it. This is what it looks like when AI is applied with purpose. Faster investigations. Clearer decisions. Better outcomes. Founded by experts including David Kennedy, Binary Defense was created to solve a problem that still exists today: organizations are overwhelmed with data, under-equipped to act, and left exposed when it counts. We changed that by building a model where experienced defenders lead, and technology works in service of their decisions. Our services include Managed Detection and Response, Threat Hunting, and Digital Risk Protection, all designed to give organizations something most tools can’t: The ability to understand what is happening and respond before it becomes something worse.
