Nucleus Security, founded in 2018 and headquartered in Sarasota, Florida, builds a unified vulnerability and exposure management platform for large enterprises, managed service providers, and application security teams. The platform aggregates data from an organisation's existing security and business tools into a single interface, combining vulnerability, threat, and asset information to help security teams identify and act on the risks that matter most.
The core function of the Nucleus Security platform is to bring structure and priority to vulnerability management at scale. By incorporating business context and threat intelligence into its prioritisation engine, it allows teams to focus remediation effort where exposure is greatest. Automated workflows reduce the manual coordination typically required between security and operations functions. The company claims its platform enables organisations to mitigate vulnerabilities ten times faster than conventional approaches.
Nucleus Security was recognised as a Challenger in the 2025 Gartner Magic Quadrant for Exposure Assessment Platforms. Its technical work spans risk-based vulnerability management, AI-driven security intelligence, data unification across disparate toolsets, and enterprise-grade workflow automation. The platform is designed to serve security teams operating at scale, including those within managed security service providers handling vulnerability management across multiple client environments.
