OpenAI deploys Daybreak cyber defence tools to support Ukraine
Ukraine’s cyber teams will use OpenAI’s Daybreak system to spot flaws and test fixes faster across critical services under heavy digital attack.
OpenAI is giving the Ukrainian government free access to its Daybreak AI cyber‑defence program, including the GPT 5.6 Sol model, to help protect civilian infrastructure from Russian cyber attacks. Working with Ukraine’s Ministry of Digital Transformation and CERT-UA, Daybreak will be used to find vulnerabilities in software, validate exploits and test fixes more quickly across sectors such as healthcare, energy and telecoms. CERT-UA handled nearly 6,000 cyber incidents in 2025, highlighting the scale of attacks on essential services and the need for automation and advanced tooling. The move extends OpenAI’s existing deployment of its cyber models with European defenders, where agencies such as ENISA and CERT Polska have already used them to discover and remediate software flaws. The partnership was announced alongside the UN General Assembly, where AI-enabled cyber risks and regulation are a central topic for governments and tech leaders.
Why it matters
For Ukraine’s cyber defenders, Daybreak adds automated help at a time when hospitals, energy systems and telecom networks are facing thousands of attacks. CERT-UA has already had to manage nearly 6,000 incidents in 2025, and OpenAI argues that keeping civilian infrastructure running now depends on protecting it from digital as well as physical strikes. By bringing the same models already used by European security agencies to Ukraine, the deal aims to speed up how quickly software weaknesses are found and patched in essential services.
