Palo Alto Networks has announced a significant expansion of its Frontier AI Defence service, giving security teams direct access to OpenAI’s specialised cybersecurity model, GPT-5.6 Daybreak, which has not previously been available for commercial use. The move, powered by a partnership between the two companies, marks a shift in how frontier AI is positioned in the cybersecurity conversation — not just as a looming threat, but as an active tool for defenders.
From insight to action
Until now, frontier AI models have mostly informed the work of Unit 42’s experts. With this expansion, those same models can operate directly inside customer environments, working under Unit 42’s direction to discover exposures, test whether they can actually be exploited, and validate full attack paths. A multi-model harness routes each task to whichever model performs best, balancing coverage, accuracy and cost. At the same time, human experts continue to verify findings and connect them to real-world threat intelligence.
Why known vulnerabilities aren’t enough
Data backs the urgency behind this shift: 36% of exposures identified by Unit 42 map to no known CVE, often arising from multiple smaller gaps that must be discovered and chained together to be understood as a genuine risk. Traditional vulnerability scanning alone no longer captures the full picture of enterprise exposure.
Speaking on the development, Sam Rubin, SVP, Unit 42 Consulting and Threat Intelligence, shared:
“Frontier AI is changing what attackers can find and how quickly exposure can become impact. By putting OpenAI’s specialised cyber models to work for defenders, we are shifting the balance of power. Unit 42 can help organisations proactively simulate adversarial attacks, discover hidden vulnerabilities before they become incidents, and accelerate remediation at machine speed.”
The company frames this as part of a broader race against time, arguing that the same AI capabilities reshaping offensive security must now be deployed at equal speed on the defensive side.
