SUNMI, a global IoT technology company, implemented Thales payShield Cloud HSM to secure payment transactions and ensure multi-regional compliance. With operations in over 70 countries, SUNMI needed to meet PCI DSS standards and manage cryptographic keys securely across AWS and Google Cloud. Thales’ HSM solution enabled encrypted, automated key management, high availability, and simplified audits while eliminating in-house security complexity. The deployment reduced latency, strengthened PCI compliance, and improved scalability for future expansion. SUNMI now supports secure remote device management, disaster recovery, and advanced applications like certificate and firmware signing.
