The company's mission is to empower organizations to become more resilient against cyber threats by providing a unified system of record for assets, vulnerabilities, and exposures, coupled with an automation engine to prevent breaches [nucleussec.com/news/nucleus-secures-series-c-funding/].

The company emphasizes that its pricing model is tailored to an organization's specific environment, with individual pricing affected by the number and type of assets in their environment.
