Case Study: Tier 1 Airline Slashes Critical Vulnerabilities by 86% with Nucleus Security

Tier 1 Airline Slashes Critical Vulnerabilities by 86% With Nucleus

Tier 1 Airline, a global carrier with a complex and highly regulated IT environment, needed a better way to manage vulnerability risk across thousands of assets and hundreds of teams. Before working with Nucleus Security and its Nucleus Security Platform, the airline struggled with incomplete asset coverage, unclear ownership, undetected compliance gaps, and inconsistent reporting that made it hard to prioritize what mattered most.

Nucleus Security became the airline’s system of record for vulnerability and exposure management, consolidating data from 160+ tools, integrating with Jira and ServiceNow, and enabling risk-based prioritization, automated workflows, and flexible reporting. The result was an 86% reduction in critical vulnerabilities within six months, more than 1,800 active users across the enterprise, and stronger accountability and visibility for security, engineering, compliance, and leadership.
