Nucleus Security Platform
Unified vulnerability and exposure management platform for risk-based prioritization and automated remediation.
Vendor Information
Nucleus Security Platform Overview
Nucleus Security is a unified vulnerability and exposure management platform that consolidates security data from across enterprise environments into a single source of truth for risk prioritization and remediation. The platform integrates with 160+ security scanners, asset management tools, and threat intelligence feeds to ingest, normalize, and correlate vulnerability data from infrastructure, cloud, and application portfolios. Unlike traditional vulnerability management tools that create alert fatigue, Nucleus applies AI-powered risk scoring with business context and real-world threat intelligence from sources including Nucleus Insights, CISA KEV (Known Exploited Vulnerabilities), and EPSS (Exploit Prediction Scoring System) to focus remediation efforts on the exposures that matter most.
The Nucleus Data Core architecture transforms raw security findings into interconnected objects—assets, vulnerabilities, threats, users, and tickets—creating a unified data fabric that enables intelligent automation. The platform features the Nucleus Query Language (NQL) for natural language queries across exposure data, a Model Context Protocol (MCP) server for governed AI interactions, and the Dynamic Automation Framework for customizable remediation workflows. Nucleus automatically matches assets from rest to runtime, deduplicates findings across tools, assigns ownership based on asset groups, and creates tickets in integrated ITSM systems like ServiceNow and Jira. The platform processes millions of assets and billions of findings across global teams with role-based access controls and live dashboards for executive visibility.
Founded in 2018 in Sarasota, Florida by former Department of Defense security experts, Nucleus Security has raised $66M in funding and serves Fortune 500 companies and government agencies. The platform holds FedRAMP Moderate Authorization and SOC 2 Type II certification, enabling deployment in regulated environments with government-grade controls and automated Plan of Action and Milestones (POA&M) processing. Nucleus is recognized as a Challenger in the 2025 Gartner Magic Quadrant for Exposure Assessment Platforms, named a Major Player by IDC MarketScape, and positioned as a Leader and Outperformer by GigaOm for its scalability, speed, and cyber risk reduction capabilities.
Key Capabilities
Standardized capabilities mapped to this product's security niche
Cross-references the vulnerability inventory against live threat feeds tracking CVEs under active exploitation in the wild, surfacing vulnerabilities with confirmed attacker activity.
Incorporates asset metadata (network exposure, business criticality, data classification) into vulnerability prioritization so that a critical CVE on an isolated internal test system ranks lower than a medium CVE on an internet-facing payment server.
Continuously discovers external-facing assets (domains, IPs, cloud services, APIs, certificates) including assets deployed outside the official inventory.
Scans cloud resource configurations and container image CVEs alongside traditional OS and application vulnerabilities in a unified risk view.
Assigns likelihood-of-exploitation scores using threat intelligence, vulnerability characteristics, and active exploit availability, independent of CVSS, which measures severity rather than exploitability.
Recommends the minimum patch set that eliminates the highest-risk exposure (accounting for shared libraries and patch co-dependencies), rather than presenting a ranked CVE list.
Creates tickets, assigns owners, and tracks remediation progress in ITSM platforms (ServiceNow, Jira), closing the loop between finding and fix rather than producing a static report.
Enforces remediation deadlines by severity, reports on SLA compliance, and escalates overdue findings through configured approval chains.
