Tenable makes Hexa AI generally available as Anthropic powers new cybersecurity workflows

Tenable has announced the general availability of Tenable Hexa AI, the agentic AI engine within the Tenable One Exposure Management Platform, alongside new AI initiatives with Anthropic to support Claude-powered workflows across the platform.

The announcements come as security teams face a growing gap between vulnerability discovery and remediation. Tenable said large language models and frontier AI models, including Anthropic’s Mythos Preview, are accelerating the discovery of previously unknown vulnerabilities at a scale that manual security workflows cannot match.

Hexa AI connects exposure data to automated remediation

Tenable Hexa AI is designed to turn exposure intelligence into coordinated action across security and IT workflows. The engine uses the Tenable Exposure Data Fabric, which combines contextualised exposure data, native telemetry, third-party data, and insights from Tenable Research, to help organisations prioritise and remediate cyber risk across modern attack surfaces.

The platform supports advanced multi-step reasoning and Model Context Protocol support, allowing security teams to build custom agents and workflows. Tenable said Hexa AI can execute end-to-end workflows across exposure surfaces in a single request, reducing the need for practitioners to connect context manually across different tools.

Its remediation capabilities include creating and routing tickets, generating custom policies, and producing audit-ready reports. The system can also provide exposure path insights by allowing practitioners to query environments through identity attributes such as service accounts, privileged users, and Active Directory groups. Tenable said this can surface exposure paths that traditional asset inventories may miss.

Eric Doerr, Chief Product Officer at Tenable, said enterprises need controls around agentic AI before they can trust automated action in security environments.

“AI Agents operating without the right guardrails and harness can be unpredictable, brittle, or unsafe in real-world enterprise environments,” said Doerr. “This is where Tenable Hexa AI shines. It’s an agentic force; a multi-domain, enterprise-ready AI engine built for end-to-end trust — one that wraps powerful models in the structure, controls and oversight they need to act reliably and safely at scale. It doesn’t just suggest the next step; it orchestrates the entire workflow to neutralize risk before it can be exploited, with the guardrails that make that autonomy something enterprises can actually trust.”

Tenable Hexa AI operates within an agentic harness intended to provide visibility, guardrails, and auditability for production environments. The product is available to Tenable One Foundation and Tenable One Advanced customers.

Anthropic expands the AI layer inside Tenable One

Tenable’s initiatives with Anthropic will bring Claude-powered workflows into Tenable Hexa AI. The companies said the work will support AI-driven exposure management, including prioritisation, remediation orchestration, and exposure analysis across modern attack surfaces.

Anthropic will also participate in EXPOSURE 2026 in Boston, where industry leaders are discussing the role of frontier AI in cyber risk and defence. Tenable said the partnership supports its push to move AI in cybersecurity beyond risk identification towards automated action.

“The volume of exposures is increasing, the time between discovery and exploit is shrinking, and security teams need a fundamentally different approach. That’s why Tenable has developed a deep working relationship with Anthropic,” said Mark Thurmond, co-CEO of Tenable. “With Claude-fueled innovations we are accelerating R&D and our exposure management roadmap, while rapidly advancing solutions like Tenable Hexa AI so customers can strengthen their preemptive security programs, powered by agentic workflows.”

Tenable said Claude will be applied to real-world cybersecurity operations, including exposure analysis and remediation workflows. Jason Clinton, Deputy CISO at Anthropic, said the collaboration is intended to help customers better understand risk, prioritise action, and respond faster as AI becomes part of security operations.
