Tenable Hexa AI launches with multistep reasoning and Anthropic partnership for faster security

Tenable Hexa AI Enters General Availability with Advanced Capabilities

Tenable Holdings Inc. announced the general availability of Tenable Hexa AI at its Exposure 2026 conference in Boston, positioning the agentic AI engine as a solution to a widening gap in AI-driven cybersecurity1

1

. The company argues that frontier AI models like Anthropic's Mythos Preview are accelerating vulnerability discovery from months to minutes, while manual remediation processes remain dangerously slow3

3

. Tenable Hexa AI operates as an orchestration layer within the Tenable One Exposure Management Platform, designed to automate workflows from exposure discovery and remediation without requiring security teams to manually stitch context together1

1

.

The agentic AI engine leverages the Tenable Exposure Data Fabric, described as the industry's most comprehensive repository of contextualized exposure data combining native telemetry, third-party data, and insights from Tenable Research3

3

. This foundation enables the system to transform fragmented technical data into prioritized, business-aligned intelligence across entire attack surfaces3

Multistep Reasoning and Model Context Protocol Support Drive Automation

The headline feature is advanced multistep reasoning, which allows Tenable Hexa AI to execute complex, end-to-end workflows spanning multiple exposure surfaces from a single request1

1

. This capability eliminates the need for practitioners to manually connect context across disparate tools during cybersecurity operations3

3

.

Model Context Protocol support represents another critical addition. The open standard created by Anthropic PBC enables customers to build custom agents and workflows that integrate with Tenable Hexa AI without requiring bespoke integration work1

1

. This extensibility allows organizations to connect the agentic AI engine directly to existing security and IT tools, deploying either Tenable's prebuilt agents or custom-built solutions3

3

.

Automated remediation workflows now handle ticket creation and routing, generate custom policies, and produce audit-ready reports so security teams can respond quickly to critical exposures3

3

. A third capability provides end-to-end exposure path insights, allowing practitioners to query environments by identity attributes including service accounts, privileged users, and Active Directory groups to surface exposure paths that traditional asset inventories miss1

Anthropic Partnership Powers Claude-Fueled Workflows

Tenable announced new AI initiatives with Anthropic to accelerate agentic capabilities across its exposure management platform2

2

. The Anthropic partnership integrates Anthropic Claude into Tenable Hexa AI workflows, applying the model to real-world cybersecurity operations including prioritization, remediation orchestration, and exposure analysis across modern attack surfaces2

2

.

"The volume of exposures is increasing, the time between discovery and exploit is shrinking, and security teams need a fundamentally different approach," said Mark Thurmond, co-CEO of Tenable2

2

. Thurmond noted that the partnership accelerates R&D and the company's exposure management roadmap while rapidly advancing solutions powered by agentic workflows2

2

.

Jason Clinton, Deputy CISO at Anthropic, stated the company is working with Tenable "to apply Claude's capabilities to help customers better understand risk, prioritize action, and respond faster"4

4

. The collaboration comes as organizations confront a rapidly evolving threat landscape shaped by frontier AI models2

Agentic Harness Addresses Enterprise Trust Concerns

Tenable designed Tenable Hexa AI to operate within what the company calls an agentic harness, providing continuous visibility, guardrails, and strict auditability over agent actions at machine speed3

3

. This architecture attempts to address trust issues that have slowed enterprise adoption of autonomous AI tooling1

1

.

"AI Agents operating without the right guardrails and harness can be unpredictable, brittle, or unsafe in real-world enterprise environments," said Eric Doerr, Chief Product Officer at Tenable3

3

. Doerr emphasized that Tenable Hexa AI "doesn't just suggest the next step; it orchestrates the entire workflow to neutralize risk before it can be exploited"1

1

.

The system delivers verifiable trust through controls and oversight designed to enable reliable and safe security orchestration at scale3

3

. This approach aims to give enterprises confidence in automating vulnerability remediation workflows that previously required manual intervention3

3

.

Tenable Hexa AI is now available to Tenable One Foundation and Tenable One Advanced customers under the company's flex pricing model1

1

. Tenable provides exposure management services to over 40,000 customers globally, with the company valued at $2.78 billion and reporting revenue of $1.02 billion4

4

. The company's stock surged 22.69% over the past week following the announcement4
