SGA Solutions said on Wednesday it obtained CC certification at the EAL4 level for its server security solution, "V6.0 for Windows Server 2025 R3".

RedCastle, based on SGA Solutions' secure OS technology, provides core security functions such as server access control, account and privilege management, audit logs and tamper prevention.

It controls access permissions at the operating system (OS) kernel level and applies customized security policies by server to block unauthorized access to important assets.

The company said the EAL4-level CC certification is meaningful because it officially verifies that RedCastle V6.0 R3, designed to meet "National Security Requirements V3.0", operates stably in the latest Windows Server 2025 environment.

SGA Solutions plans to use the certification to strengthen its push into the public sector by responding to the National Network Security Framework (N2SF) and zero trust (microsegmentation). Based on business experience and references accumulated in the public and defense sectors, it plans to expand into data server security markets at financial companies and large enterprises, where adoption of generative AI and large language models (LLMs) is widening.

Young-cheol Choi (최영철), CEO of SGA Solutions, said that in AI- and cloud-centered IT environments, data has higher value, making server-level security control and microsegmentation essential rather than optional. He said the company would solidify its technology leadership in the AI security market.
