SK Telecom announced that its Haein Cluster, an AI data center infrastructure based on NVIDIA's Blackwell GPU, has received Cloud Service Security Certification (CSAP) from the Korea Internet & Security Agency (KISA) on July 6. SK Telecom is the first company in South Korea to obtain CSAP certification for an AI cloud service provider using Blackwell GPUs.

CSAP is a system that verifies the security of cloud services used by public institutions. The Haein Cluster has received certification in the Infrastructure as a Service (IaaS) category.

The Haein Cluster consists of over 1,000 Blackwell GPUs configured as a single cluster. This system combines multiple GPUs to handle large-scale computations. With this certification, SK Telecom has enhanced the credibility and technological trustworthiness of its GPU cluster's security.

Notably, the Haein Cluster passed security standards while being actively utilized in a government-led independent AI foundation model project, rather than just in a dormant state. The cluster meets security requirements for public cloud services, including network separation and data isolation, establishing a foundation for expanding AI infrastructure projects in the public and financial sectors.

With this certification, SK Telecom strengthens its position in the domestic sovereign AI cloud market. Sovereign AI refers to AI systems built and operated independently by a country using its own data and infrastructure. Unlike traditional cloud services that offer general solutions, AI cloud services are specialized for AI tasks such as learning, inference, and data processing. The Haein Cluster serves as the learning infrastructure for the government-led independent AI foundation model project, demonstrating its capabilities as a sovereign AI infrastructure.

Kim Myung-guk, head of the AI Factory at SK Telecom, stated, "The Haein Cluster has established itself as the first AI cloud service provider based on Blackwell GPUs to receive CSAP certification, positioning itself as a sovereign AI infrastructure. We will continue to enhance our contributions in the public infrastructure sector."
