COLUMBIA, Md., June 22, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced it is working with OpenAI as part of the OpenAI Daybreak Cyber Partner Program. The collaboration brings together OpenAI's frontier AI capabilities, including GPT-5.5, and Tenable's leadership in exposure management to help organizations better understand cyber risk, prioritize action and stay ahead of attackers through Tenable product and service workflows.

The announcement comes as AI is reshaping the threat landscape. Attackers are already using AI to accelerate reconnaissance, automate vulnerability discovery and compress the window between exposure and exploitation. Security teams face a growing asymmetry: the volume and complexity of potential exposures is expanding faster than any team can manually assess, while the time available to act continues to shrink.

The Tenable One Exposure Management Platform was built for exactly this challenge. Rather than generating more findings, Tenable One helps organizations understand which exposures actually matter. Powered by the Tenable Exposure Data Fabric, the platform connects exposure intelligence from across the modern attack surface and applies the context needed to distinguish what is merely vulnerable from what is truly risky. Combined with frontier AI capabilities, this rich foundation helps organizations move from analysis to action faster, enabling security teams to focus on the exposures most likely to impact the business before attackers can capitalize on them.

The collaboration is expected to focus on several areas, including:

• Advancing cybersecurity research and exposure intelligence
• Accelerating the identification and prioritization of exploitable exposures and attack paths
• Improving how security teams prioritize, validate and respond to the exposures that matter most
• Streamlining security operations and accelerating risk reduction

“The AI era requires a fundamentally new approach to cybersecurity,” said Eric Doerr, Chief Product Officer, Tenable. “Attackers are moving faster and operating at a scale that makes purely reactive security untenable. As part of OpenAI’s Trusted Access for Cyber program, Tenable is evaluating how GPT-5.5 can help accelerate defensive workflows through secure product integrations, enabling customers to stay ahead of attackers and move faster with confidence. This is what proactive security looks like in practice.”

The announcement underscores Tenable's continued investment in AI-powered exposure management and its commitment to helping customers proactively reduce cyber risk in an increasingly complex threat landscape.
