Case Study: a global merchant service provider strengthens cybersecurity and remediates a breach with Coalfire

Global Merchant Service Provider investigates a $10M breach with Coalfire

The customer, a global merchant service provider, faced a significant challenge after a sophisticated international hacking ring breached its systems, resulting in a $10 million ATM cash-out. To investigate the breach and reassess its cybersecurity posture, the organization hired vendor Coalfire for its Cyber Risk Advisory and Compliance services.

Coalfire implemented a comprehensive solution that included a security engineering assessment and a rearchitecture of the client's PCI infrastructure to exceed compliance standards. This work helped identify the attackers' techniques, contributed directly to their arrest and prosecution, and defined long-term security strategies that have prevented subsequent breaches.
