Tenable Holdings, Inc. (NASDAQ: TENB) announced that Tenable One Cloud Exposure has achieved FedRAMP High and Impact Level (IL) 5 authorization, one of the U.S. government’s most stringent security certifications. This milestone significantly expands Tenable’s opportunities to support highly sensitive federal environments, including those used by the Department of War and intelligence agencies. The authorization enables Tenable to support new mission-critical use cases, such as classified and tactical edge deployments, providing a competitive advantage in the federal space.

Part of the Tenable One Exposure Management Platform, Tenable One Cloud Exposure is an actionable cloud security solution that provides unified visibility and AI-powered contextual insights. It helps organizations proactively identify and close critical exposure gaps across the entire cloud lifecycle. The new authorization builds on Tenable FedRAMP Moderate authorizations for both Tenable One Cloud Exposure and Tenable One.

As federal agencies accelerate cloud modernization and AI adoption, they face a complex landscape of misconfigured workloads and fragmented security tools. Tenable One Cloud Exposure consolidates critical cloud security functions into a single, cost-efficient solution. By leveraging advanced identity analytics, the platform enforces Zero Trust principles that align with Department of War CIO mandates to ensure mission-critical resilience and cyber readiness.

Tenable One Cloud Exposure is a comprehensive Cloud Native Application Protection Platform (CNAPP) designed for sensitive government cloud environments. It delivers unified visibility across infrastructure, identities, and workloads, alongside proactive identity risk management and enforcement of least privilege. The solution ensures continuous compliance with evolving federal cybersecurity standards.

“Achieving FedRAMP High authorization is a powerful validation of our public sector commitment and our ability to protect the most sensitive cloud workloads,” said Bob Huber, Chief Security Officer and President of Tenable Public Sector, LLC. “We’re proud to provide federal agencies with a unified exposure management platform that meets their toughest challenges: reducing risk, maintaining compliance and securely adopting AI with confidence.”

Tenable One Cloud Exposure received FedRAMP High authorization through UberEther’s AIM Advantage platform.

Tenable Holdings, Inc. announced on June 22, 2026, that it is collaborating with OpenAI as part of the OpenAI Daybreak Cyber Partner Program. The partnership integrates OpenAI's frontier AI capabilities, including GPT-5.5, with Tenable's exposure management platform to help organizations better understand cyber risk, prioritize action, and stay ahead of attackers. This collaboration addresses the growing asymmetry security teams face as attackers use AI to accelerate reconnaissance and automate vulnerability discovery, shrinking the window between exposure and exploitation.

The Tenable One Exposure Management Platform, powered by the Tenable Exposure Data Fabric, connects exposure intelligence across the modern attack surface. By applying context to distinguish between vulnerable and truly risky exposures, the platform enables organizations to move from analysis to action faster. The integration with GPT-5.5 aims to enhance this capability, allowing security teams to focus on exposures most likely to impact the business.

Collaboration Focus Areas

The partnership is expected to concentrate on several key initiatives to strengthen cybersecurity postures:

• 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 critical exposures
• 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."

Strategic Implications

The announcement underscores Tenable's continued investment in AI-powered exposure management. By leveraging frontier AI, Tenable aims to help customers proactively reduce cyber risk in an increasingly complex threat landscape. The collaboration highlights the shift towards proactive security measures that combine advanced AI with deep exposure intelligence to counter evolving threats.
