Cognizant has announced that it has joined OpenAI’s Daybreak Cyber Partner Programme and is deploying GPT-5.5 with Trusted Access for Cyber to strengthen its Frontier AI Cyber Defense services for enterprise clients.
The company said the enhanced services are designed to help organisations move more quickly from identifying security vulnerabilities to implementing validated and tested remediation measures. The AI-powered capabilities will be integrated across a range of cybersecurity workflows, including secure code review, threat modelling, vulnerability discovery and validation, detection engineering, threat hunting and incident investigation and response.
According to Cognizant, the technology is being applied internally across its own products, platforms and code repositories before being introduced into customer engagements. The company described this approach as operating as its own “Client Zero”, enabling it to test and refine the technology within its own environment before deploying it for clients.
Cognizant said it employs more than 5,000 cybersecurity professionals and has maintained a dedicated cybersecurity practice for more than a decade, providing security services to enterprise customers across multiple industries.
Sandra Notardonato, Global Head of Partner Development and Influencer Relations at Cognizant, said the emergence of frontier AI had transformed cyber defence but stressed that the value of advanced AI models depends on how effectively they are deployed within real-world enterprise environments.
”Frontier AI has changed the equation for cyber defence, but a model’s power only matters in how it is applied inside a real enterprise,” she said.
OpenAI also highlighted the importance of combining advanced AI capabilities with strong governance. Colleen Kapase, the company’s Vice President of Strategic Global Partnerships and Ecosystems, said Cognizant’s cybersecurity expertise and global delivery capabilities would help organisations adopt AI-powered security tools responsibly.
”Cognizant brings cybersecurity domain depth and delivery scale to help enterprises apply these capabilities responsibly, with the oversight and governance required to move from discovery to validated remediation,” Kapase said.
The two companies said their collaboration will operate within a governance framework that incorporates scoped access controls, continuous monitoring and human oversight throughout each stage of the cybersecurity workflow, aiming to ensure that AI-assisted security operations remain both effective and accountable.
