Nucleus Security, the leader in unified vulnerability and exposure management, announced a $20 million Series C funding round led by Delta-v Capital. Nucleus has emerged as the system of record for assets, vulnerabilities, and exposures, and the automation engine to remediate what matters most to prevent breaches.

Nucleus is leading an industry shift away from traditional vulnerability scanning to building an exposure management orchestration platform that operationalizes context, adapts to each enterprise, and closes the gap between data and action. Nucleus integrates security and asset data from more than 200 tools, business context, and AI-driven exploit intelligence into a shared, up-to-date view of exposure to drive prioritized action and measurable risk reduction across the organization.
