Vulnerability Management

Nucleus Security Platform

Unified vulnerability and exposure management for risk-based prioritization and remediation.

Nucleus Security Platform Overview

What it does

Nucleus Platform is a Risk-Based Vulnerability Management (RBVM) and exposure management platform that consolidates findings from 200+ scanners, asset inventories, and threat feeds into one system of record for assets, vulnerabilities, and threats. The Nucleus Data Core normalizes, deduplicates, and matches that data, and the Nucleus Helix engine runs reasoning agents that prioritize and route exposures. Risk scoring combines asset context with exploitation signals from Nucleus Insights, CISA Known Exploited Vulnerabilities (KEV), and the Exploit Prediction Scoring System (EPSS), targeting exploitable risk over CVSS severity.

How it works

Connectors ingest scanner, cloud, container, application security, and Configuration Management Database (CMDB) data, which the Data Core links into persistent asset, vulnerability, threat, and ticket objects. Weighted risk factors (asset criticality, data sensitivity, internet exposure, compliance scope) and daily-refreshed Nucleus Threat Ratings produce a unified score. The Dynamic Automation Framework assigns ownership, syncs tickets bi-directionally with IT Service Management (ITSM) tools, enforces SLAs and time-boxed exceptions, and groups vulnerabilities into single Fixes. Analysts query the estate with the Nucleus Query Language (NQL), question the Helix agent in plain language, or connect AI tools through the Model Context Protocol (MCP) Server.

Credentials and traction

Nucleus holds FedRAMP Moderate authorization for NucleusGov and an annual SOC 2 Type II attestation. It was named a Challenger in the 2025 Gartner Magic Quadrant for Exposure Assessment Platforms, a Major Player in the IDC MarketScape: Worldwide Exposure Management 2025, a Strong Performer in the Forrester Wave: Unified Vulnerability Management Solutions, Q3 2025, and a Leader and Outperformer in the 2025 GigaOm Radar for Continuous Vulnerability Management. Customers include Bank of Hope, NRECA, Motorola, Paychex, and Orange Cyberdefense.

Key Capabilities

mapped to solution categories
Risk-Based Vulnerability Management (RBVM)

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.

Aggregates and deduplicates findings from network scanners, endpoint agents, cloud scanners, and third-party tools into one normalized record for cross-estate risk ranking.

Time-boxed risk acceptance workflow with documented approvals that keeps exceptions active and tracked as new scan data is ingested, rather than silently closing or re-opening findings.

Continuous Threat Exposure Management (CTEM)

Generates trend reports on exposure posture (new exposure, remediated exposure, outstanding exposure by severity), in business language suitable for security program reviews.

Maps the discovered exposure inventory against active threat actor targeting and in-the-wild exploitation data to surface vulnerabilities under active attack.

Creates and tracks remediation tasks across teams and ticketing systems, measuring exposure reduction over time rather than simply listing open findings.

Confirms whether prioritized exposures are actually exploitable by running or ingesting adversarial validation results, such as breach and attack simulation or automated penetration testing delivered natively or by an integrated third-party tool, and re-ranks or closes exposures on the outcome so the queue reflects confirmed rather than theoretical risk.

Ranks exposures by their accessibility, visibility, and exploitability combined with asset criticality, business impact, and the security controls already in place, so a medium-severity issue on a critical, reachable, unprotected service outranks a high-severity issue on an isolated or compensated one.

Discovers assets and their exposures across the external, internal, cloud, and end-user attack surfaces, covering endpoints, network and on-premises infrastructure, identities and entitlements, hosts, containers, IoT and OT, and cloud platforms and applications, either through native discovery or by integrating third-party discovery sources, and reports vulnerabilities, misconfigurations, unmanaged assets, and compliance gaps in one inventory.

Tracks the life cycle of exposures through a centralized, aggregated view supported by automated workflows.

Groups assets into business processes, applications, or protection surfaces with named owners and criticality, so each exposure management cycle is scoped to what the business must protect and exposure is assessed and reported per scope rather than across the whole estate.
