Stealien said that an autonomous AI security agent it helped develop took first place at the international cyber exercise 'APEX 2026.'
APEX 2026 was held on the 16th and 17th at COEX in Seoul, and 23 countries, including NATO member states, participated.
The AI-driven Blue Team, formed for the first time this year, automated attack-situation analysis and response using an autonomous AI security agent and an orchestration system, and recorded training performance up to 3 times that of human participant teams.
Stealien announced on the 21st that an autonomous AI security agent it helped develop took first place at the international cyber exercise 'APEX 2026.'
The official name of APEX is Allied Power Exercise. The exercise aims to strengthen global cyber security cooperation and deterrence, and is hosted through cooperation among the National Intelligence Service, NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE), and the Ministry of National Defense. APEX 2026 was held on the 16th and 17th at COEX in Seoul, and 23 countries, including NATO member states, participated this year.

This year, an AI-driven Blue Team was formed for the first time to verify AI-based autonomous defense capabilities. The AI-driven Blue Team used an autonomous AI security agent and an orchestration system, which took charge of coordinating each task. Through this, it automated attack-situation analysis and response processes, and its training performance reached up to 3 times that of human participant teams.
The AI-driven Blue Team was operated as a public-private-military cooperation project promoted by the National Cyber Security Center (NCSC) of the National Intelligence Service. Participating institutions and experts included Stealien, the Cyber Operations Command of the Ministry of National Defense, the National Security Research Institute, and the Korea Financial Security Institute, and each institution shared responsibility for architecture design, AI models, and system infrastructure to jointly build the system.
Stealien researchers led the architecture design of the AI security agent and the development of the core system. The key developers were researchers Jeong Geon-u, Baek Bu-seung, and Kim Myeong-hyeon, and Jeong Geon-u was also the youngest participant in APEX 2026. Jeong Geon-u was responsible for architecture design and core system implementation, Kim Myeong-hyeon handled the architecture and core system, and Baek Bu-seung was in charge of architecture design and front-end development.
Jeong said the significance of this achievement lies in applying an AI-based defense system to an actual cyber exercise, adding that the meaning is substantial.
Jeong added that the team plans to continue researching AI security technologies that encompass both attack and defense, based on offensive security technologies and AI research capabilities. Park Chan-am, CEO of Stealien, said the achievement is a case that proves Stealien's technological prowess and the strength of Korea's security talent on the international stage by combining real-world hacking experience with AI research capabilities, and expressed the company's commitment to supporting the Republic of Korea's contributions to international cyber security in the AI era.
