OpenAI announced on September 23, 2026 that it will grant the Ukrainian government access to its Daybreak AI program to bolster the cyber defense of civilian infrastructure. The move, revealed alongside Ukrainian Consul General Dmytro Kushneruk at the United Nations General Assembly, aims to help Ukrainian teams identify software vulnerabilities and develop fixes more quickly as the country endures sustained cyber attacks from Russia.
What happened
OpenAI’s Daybreak platform provides authorized security teams with advanced artificial intelligence tools for a range of defensive tasks. These include reviewing legacy software, investigating suspicious activity, validating discovered vulnerabilities, and testing patches. By extending this capability to Ukraine’s Ministry of Digital Transformation, OpenAI intends to empower both public and private entities that keep essential services running.
The announcement highlighted the scale of the cyber threat facing Ukraine. In 2025, the national cyber incident response team, CERT‑UA, handled nearly 6,000 incidents, spanning attacks on hospitals, energy providers, and telecommunications networks. These incidents illustrate the dual pressure of physical and digital assaults on critical infrastructure.
OpenAI’s leadership underscored the significance of the partnership. Sasha Baker, Head of National Security Policy at OpenAI, said the company is proud to support Ukraine’s cyber defenders and wants to give them more capable tools to find and fix vulnerabilities before threats materialize. George Osborne, Head of OpenAI for Countries, added that cyber defense has become a central component of national security for Ukraine.
The initiative builds on OpenAI’s prior collaborations with European cyber agencies. The EU’s ENISA agency has already used OpenAI models to locate vulnerabilities in software across EU institutions, leading to successful patches. In Poland, the national cyber agency CERT Polska leveraged the same models to uncover six flaws in third‑party router software, prompting the vendor to release corrective updates.
Why it matters
Cyber attacks on civilian infrastructure can disrupt health care, energy supply, and communications—services that are vital for daily life and economic stability. By equipping Ukrainian defenders with AI‑driven analysis tools, OpenAI aims to shorten the time between vulnerability discovery and remediation, reducing the window attackers have to exploit weaknesses.
The partnership also signals a broader recognition that cyber resilience is a prerequisite for national security. As physical attacks on infrastructure continue, the digital layer becomes an equally critical front. Strengthening cyber defenses helps preserve public trust, maintain essential services, and safeguard the civilian population from the cascading effects of service outages.
The bigger picture
OpenAI’s Daybreak program is part of a growing trend of AI companies providing specialized tools for authorized security work. The platform’s capabilities—automated code review, anomaly detection, and rapid patch testing—reflect a shift toward AI‑augmented cyber operations that can handle the volume and complexity of modern threats.
Europe’s experience with OpenAI’s models illustrates the practical impact of such tools. ENISA’s use of the technology across EU institutions led to the identification and remediation of multiple software flaws, demonstrating that AI can complement traditional security processes. Similarly, CERT Polska’s success in finding router vulnerabilities shows that national cyber agencies can leverage AI to uncover hidden issues in third‑party products.
OpenAI’s decision to extend Daybreak to Ukraine aligns with its stated mission to support governments in defending critical infrastructure. The move also underscores the company’s willingness to engage directly with nations under acute cyber pressure, positioning its technology as a public‑good asset in the geopolitical arena.
What happens next
OpenAI plans to work closely with Ukraine’s Ministry of Digital Transformation and CERT‑UA to integrate Daybreak into existing security workflows. The collaboration will focus on rapid vulnerability assessment and fix validation for civilian networks. While specific timelines for deployment were not disclosed, the partnership aims to deliver tools “now” to address the immediate threat landscape.
The broader rollout may serve as a model for other nations facing similar pressures, as OpenAI has already supplied its cyber models to defenders in France, Germany, Poland, and other European countries. Future expansions will likely depend on requests from governments and the ability of OpenAI’s platform to meet authorized security use cases.
Overall, the extension of Daybreak to Ukraine represents a concrete step toward AI‑enhanced cyber resilience for a country at the front line of both physical and digital conflict.
