Nagomi Security is a cybersecurity company based in New York, NY, that offers a Continuous Threat Exposure Management (CTEM) platform focused on proactive defense. The company's core product, the Nagomi Proactive Defense Platform, unifies data across an organization's assets, existing security controls, and threat intelligence to evaluate whether current defenses are performing effectively against real-world threats. Rather than deploying new security tooling, Nagomi's platform is designed to work with an organization's existing security stack. It continuously measures the performance of security controls, identifies gaps, and prioritizes remediation actions based on actual threat exposure. The platform also includes a Program Performance Management module and the Nagomi Control product, which is aimed at bringing CTEM workflows into operational practice. The platform generates board-ready reporting and is intended to help security leaders — particularly CISOs — communicate security effectiveness to executive stakeholders and demonstrate ROI on existing security investments. It addresses the concept of "security debt," which refers to accumulated gaps in security controls despite prior technology investments. Nagomi's target market is enterprise security teams seeking to validate and optimize their existing security programs. The company has been recognized as a 2024 Gartner Cool Vendor in the Modern Security Operations Center category and was a finalist in the 2025 SC Awards under the Best Continuous Threat Exposure Management Solution category. Nagomi is also a participant in the Microsoft for Startups Pegasus Program.
