Nucleus Raises $20 Million for Exposure Management

Nucleus Security has announced raising $20 million in a Series C funding round led by Delta-v Capital. The Sarasota, Florida-based vulnerability and exposure management company says the fresh investment will help it scale operations and deepen intelligence and automation across cloud and AI-driven environments. Founded in 2018, Nucleus has now raised over $86 million to date across four investment rounds.

The company says its exposure management platform integrates data from more than 200 connectors, unifying business context and AI-based intelligence to support risk prioritisation and faster remediation. According to Nucleus, its vendor-agnostic approach covers exposure across tools, users, environments and business units, enabling coordinated action.
