Nucleus Security, founded in 2018 and headquartered in Sarasota, Florida, develops a unified vulnerability and exposure management platform aimed at large enterprises, managed service providers, and application security teams. The platform consolidates data from an organisation's existing security and business tools into a single interface, combining vulnerability, threat, and asset data to help security teams prioritise and act on critical exposures.
The core technical challenge Nucleus addresses is the fragmentation of security data across multiple tools. Its platform integrates these sources automatically, applies business context and threat intelligence to rank exposures by risk, and automates the workflows involved in remediation. The company claims this approach enables organisations to mitigate vulnerabilities ten times faster than conventional methods.
Nucleus Security's platform spans several technical domains relevant to security engineering roles:
- Risk-based and exposure-focused vulnerability management
- AI-driven threat intelligence and prioritisation
- Data integration across heterogeneous security and business toolchains
- Automation of vulnerability management workflows at enterprise scale
- Asset data management and correlation
The company was recognised as a Challenger in the 2025 Gartner Magic Quadrant for Exposure Assessment Platforms. It serves large enterprises as well as MSPs and MSSPs that manage vulnerability programmes across multiple client environments.
