OpenAI Unveils AI Cyber Defense Strategy for South Korean Enterprises, Launches Integrated Solution 'Daybreak'
OpenAI has unveiled 'Daybreak,' an integrated cyber defense solution that leverages artificial intelligence to proactively detect security vulnerabilities in enterprise systems and support remediation, to South Korean companies.
OpenAI hosted the 'OpenAI Cyber CXO Roundtable' on the 16th at The Westin Seoul Parnas. The event, attended by approximately 60 South Korean corporate executives including chief information security officers (CISOs), focused on the evolving cyber threat landscape in the AI era and enterprise response strategies.
The event opened with remarks from Kim Kyung-hoon, head of OpenAI Korea. Dominic Grillo, head of technical success, and Wana Tun, security engineer, then delivered presentations explaining the dual-sided transformation AI has brought to both offense and defense.
OpenAI assessed that as AI's ability to identify software vulnerabilities and analyze attack paths rapidly improves, the window for enterprises to respond to cyberattacks is shrinking. However, the company explained that defenders—unlike attackers—can provide AI with the code and operational context of systems they manage, enabling them to use AI to find and resolve issues before attackers can exploit them.
Daybreak, introduced at the event, connects OpenAI's AI models, the development tool Codex, and the security tool Codex Security to existing security workflows. It enables enterprises to integrate AI into security tools and processes they already use to discover vulnerabilities, validate real-world exploitability in controlled environments, generate remediation proposals, and verify their effectiveness.
Final decisions on applying remediation patches rest with security personnel and developers after reviewing AI-generated validation evidence and test results. The solution can be applied to code security reviews, threat investigations, and authorized security testing. The core principle is building a continuous cyber defense framework premised on human oversight, access controls, and safety guardrails.
OpenAI stated that a significant portion of major South Korean companies have already adopted Daybreak or are evaluating adoption.
OpenAI also shared its internal experience building a 'Defense Factory.' The Defense Factory is an operational system that connects AI agents, repeatable workflows, and isolated execution environments to existing security and development tools to continuously discover and resolve vulnerabilities. It is structured so that security and development teams respond jointly—routing discovered issues to responsible teams and carrying them through remediation and verification.
OpenAI emphasized that enterprises must clearly define the data and systems AI can access and the scope of tasks it can perform, with critical decisions and changes subject to human review.
The company also offered recommendations on security performance metrics. OpenAI advised that evaluation should be based on actual risk reduction rather than AI usage volume or detection counts. Performance should be judged primarily on how quickly major security risks are resolved and whether remediation measures have been verified as effective.
"To quickly identify and respond to major security risks in the AI era, enterprises must treat cybersecurity as a core management priority," said Kim Kyung-hoon. "We will help South Korean companies integrate AI into their existing security frameworks, validate effectiveness in the field, and evolve this into sustained defensive capability."
