Case Study: Fortune 500 Payments Company achieves 89% Remediation Rate with Nucleus Security

Fortune 500 Payments Giant Automates Exposure Management at Scale with Nucleus

Fortune 500 Payments Company, a global payments giant operating across dozens of markets and business units, needed a way to scale vulnerability and exposure management across rapid M&A activity, cloud complexity, and fragmented security stacks. Using the Nucleus Security Platform, the company aimed to centralize visibility, improve prioritization with custom threat intelligence, and reduce the manual burden of ingestion, triage, and ownership.

Nucleus Security implemented an API-first, automation-led program with 200+ workflows, project-level segmentation for 22+ acquired entities, and custom intelligence to drive contextual scoring and remediation. The results included unified governance across business units, a reduction of more than 20 million API calls, and an 89% remediation rate across millions of findings, helping the company operate its exposure management program at enterprise scale.
