Nucleus Security Bags $20M to Strengthen Exposure Management

Nucleus Security Inc. has raised $20 million in new funding to improve its vulnerability and exposure management platform. The company plans to use the capital to enhance product features, expand platform capabilities, and support more customer deployments.

Founded in 2018, Nucleus focuses on exposure management instead of just basic vulnerability scanning. Instead of looking at security issues in isolation, the company treats vulnerabilities, digital assets and risk signals as connected data. It organizes and links this information to help businesses make better security decisions.

Its platform acts as a central system that collects data from more than 200 security, asset management and infrastructure tools. These tools cover IT systems, cloud environments, applications and even operational technology.

The platform gathers all vulnerability data in one place, prioritizes risks based on context and helps teams manage the repair process. It also connects vulnerabilities with asset importance, ownership details and known exploit risks. The system then turns this information into clear actionable steps for remediation teams.

The platform also includes automation features. These tools coordinate tasks across ticketing systems and operational platforms, allowing security teams to monitor progress and maintain an updated view of their overall risk exposure.

Nucleus supports continuous exposure assessment across development, production and operational systems. Its use cases span enterprise IT, application security, cloud security and industrial or operational technology environments.

Over the past year, many enterprise customers have replaced their older, expensive, in-house vulnerability management systems with Nucleus’ platform, as those legacy tools no longer meet resilience and security needs.

Some well-known Nucleus customers include Autodesk, CBRE, Cisco, JC Penney, the Premier League, RSA Insurance, Swisscom, Udemy, the American Red Cross and Australia Post.

The Series C funding round was led by Delta-v Capital, with Arthur Ventures also participating. With this latest investment, Nucleus has now raised about $86.1 million in total funding.
