Nucleus Security offers a cloud-based platform that consolidates asset, vulnerability, and exposure data from more than 200 security and business tools into a single system of record. The software layers business context and AI-driven exploit intelligence to deliver prioritized, actionable remediation plans, replacing traditional vulnerability scanners and home-grown tools that struggle at enterprise scale. Customers use Nucleus to orchestrate exposure management across IT, cloud, application, and OT environments, enabling faster risk reduction and measurable security outcomes. In 2025, the company saw a wave of enterprise replacements, underscoring accelerating demand for its solution. As a FedRAMP-authorized vendor, Nucleus is also positioned for federal and defense contracts. The firm plans to use its new capital to scale go-to-market operations and further enhance its orchestration and automation capabilities, aiming to define the next phase of the exposure management market.
