Nucleus Security is an outstanding vulnerability management orchestration platform that fits well in modern, complex environments where security data comes from multiple tools and teams.
Matt N.
Senior Security Architect
There is a huge need to aggregate vulnerabilities from your entire organization, not just infrastructure. Nucleus gives you that ability and helps make sense of it all. Without it, you might just be spending a lot of time and effort patching the wrong vulnerabilities.
Kate B.
Vulnerability Management Engineer
The ability I have to allow different patching teams access to the information that will make the greatest impact with the work that they are doing has been a great experience. The customization in the UI…is something I have not had experience with in other Vulnerability Management tools.

Frequently Asked Questions About the Nucleus Platform
What does the Nucleus platform do?
The Nucleus platform orchestrates the full exposure management lifecycle in one unified system of record for exposures, assets, and threats. It ingests and normalizes data from 200+ security tools, prioritizes risk using AI-powered threat and business context, and automates remediation workflows and ownership assignment. The result is continuous, measurable exposure reduction.
What is the Nucleus Live Data Core?
The Nucleus Live Data Core is the data foundation that powers the entire platform. It continuously ingests signals from 200+ sources and normalizes, deduplicates, enriches, and contextualizes that raw data into a live, accurate view of your organization’s exposure. Teams operate from decision-ready data instead of fragmented, stale feeds, making it the system of record for enterprise exposure intelligence.
How does Nucleus prioritize vulnerabilities?
Nucleus moves beyond CVSS severity scores by combining real-world threat intelligence with asset and business context. Nucleus Insights, the platform’s AI-powered intelligence feed, enriches every finding with exploitation signals including the Nucleus Threat Rating, malware association, zero-day status, and ease of attack. Custom risk scoring models layer on top, so teams focus on the small percentage of vulnerabilities that pose actual, immediate risk.
How does Nucleus Security automate remediation?
Nucleus automatically assigns ownership, creates bi-directional tickets in ServiceNow and Jira, tracks SLAs, manages exceptions, and routes work to the right teams with remediation and mitigation instructions. This eliminates the manual handoffs and routing errors where exposure remediation typically stalls. Every remediation workflow is tracked and auditable, giving security and business stakeholders a clear view of what is fixed, in progress, or at risk of breaching SLA.
Can Nucleus Security handle enterprise scale?
Yes. Nucleus is built to perform at a scale where other platforms slow down or break. One Fortune 500 customer manages 1.9 billion active vulnerabilities on the platform. Nucleus handles billions of findings across globally distributed teams, on-premises, cloud, application, and OT environments, and complex multi-tenant organizational structures without degrading performance.
How is Nucleus different from other exposure management platforms?
Most exposure management tools fall into one of two traps: flexible platforms that require significant engineering investment to configure and maintain, putting DIY responsibility on the buyer; or point solutions that address a single step in the process without a unified data and execution layer underneath. Nucleus is purpose-built to solve the full lifecycle, combining enterprise-grade infrastructure, continuous data unification, threat-informed prioritization, and orchestrated remediation in one system, without custom code or long implementation cycles.
What integrations does Nucleus support?
Nucleus connects to 200+ data sources out of the box, including scanners, cloud security tools, asset management systems, ITSM platforms, threat intelligence feeds, EDR, CSPM, SAST, DAST, and OT solutions. Key integrations include Qualys, Tenable, Wiz, CrowdStrike, ServiceNow, Jira, AWS, and Palo Alto. Nucleus fits into your existing stack without requiring you to replace tools that are already working.
