What Nucleus Security is

Nucleus Security is a vulnerability management platform for large enterprises and government organizations. It brings security data together, prioritizes vulnerabilities using asset context, business impact, and threat intelligence, and automates remediation workflows. Nucleus Discover identifies exposure to newly disclosed and zero-day vulnerabilities before scanner signatures or scan cycles. With Nucleus Helix, teams can ask questions about security data in plain language, investigate exposure, identify ownership, and create workflows. The platform automates ownership, bi-directional ticketing, and SLA tracking, and provides role-aligned dashboards and reports for security leaders, analysts, and remediation owners. Its integrations page lists 184 connectors across scanners, cloud security, asset inventory, ticketing, threat intelligence, and SSO. FlexConnect can process data from any source and format, according to Nucleus. The company says the platform is FedRAMP Moderate Authorized and supports POA&M process automation, NIST RMF, and CISA BOD alignment. Pricing depends on the organization's environment and asset types and counts; customers must contact Nucleus for accurate pricing. Nucleus says one Fortune 500 customer manages 1.9 billion active vulnerabilities on the platform.
