Implement agentic AI in cybersecurity – Tenable Hexa AI

As frontier AI models collapse the traditional exploit window, Tenable Hexa AI transforms the security operating model from manual triage to agentic orchestration. See how you can automate vulnerability remediation and super-charge exposure management with Tenable Hexa AI.

Why you need to implement agentic AI in cybersecurity (and specifically, in vulnerability management) 

For most of my career in cybersecurity, we’ve operated on a fundamental, if unspoken, assumption: We had a grace period. Whenever a new vulnerability was discovered, we knew we had time, often weeks or months, before adversaries would begin exploiting it. The time between vulnerability discovery and exploitation gave us breathing room. It gave us time to patch, triage, and remediate.

But not any more. The gap between discovery and exploitation has been shrinking for years, and the vulnerability discovery capabilities demonstrated by frontier AI models like Claude Mythos are narrowing it even more.

We have entered the era of AI speed. When an LLM can unearth a 27-year-old vulnerability in a hardened OS in minutes, and then weaponize it in seconds, old defensive cycles can’t keep up, and that’s untenable. 

This is why I’m so excited to announce the general availability of Tenable Hexa AI, the agentic engine of the Tenable One Exposure Management Platform, at EXPOSURE 2026: because it’s designed to help your organization address the escalating, AI-driven pace of vulnerability discovery.

The agentic AI imperative in cybersecurity: Scale your preemptive defense to match machine speed with agentic innovation from Tenable

Tenable Hexa AI is built to be a force multiplier and a flexible engine for innovation. Featuring a suite of built-in agents ready to automate assessment configuration, asset tagging, dashboard creation, ticket creation, and more, Tenable Hexa AI is designed to help your organization overcome the operational challenges deepened by adversarial AI use. 

When the window between discovery and exploitation hits near-zero, security teams locked in manual vulnerability management operating models are forced into a state of perpetual emergency. Manually stitching together context and telemetry from cloud, identity, OT, and vulnerability silos in an arduous effort to prioritize remediation for downstream IT and DevOps teams is a losing battle. 

And when you can’t provide clear, risk-based remediation priorities to IT and DevOps teams, you end up bombarding them with seemingly urgent tickets that may not in fact be critical to your organization. Constant shifts in remediation priorities and endless debates over what needs fixing and why is not sustainable. It creates friction and causes you to lose the cybersecurity race.

In a world where attackers move at machine speed, only comprehensive exposure intelligence combined with the agentic AI orchestration capabilities provided by the Tenable One Exposure Management Platform can give you clarity and control. 

Tenable Hexa AI doesn’t just tell you where you are vulnerable; it mobilizes your preemptive defense.

Capabilities of Tenable Hexa AI

With this GA release, Tenable delivers foundational capabilities to help your organization accelerate the pace of vulnerability discovery and remediation, including:

• Your choice of agents – Use our pre-built, out-of-the-box agents to start reducing risk immediately, or use the Model Context Protocol (MCP) server built into Tenable Hexa AI to create custom agents tailored to your organization’s environment.
• Advanced multi-step reasoning – Tenable Hexa AI executes complex, end-to-end workflows spanning your attack surface (e.g., IT, cloud, identity, OT, etc.) in a single request, eliminating the need for practitioners to toggle between views to get exposure context. It understands that a CVE in your web app is a critical threat specifically because it is linked to a privileged service account with a path to your sensitive data.
• Automated remediation workflows – Tenable Hexa AI orchestrates remediation workflows, automatically creating and routing tickets, generating custom policies, and producing audit-ready reports, so security teams can act fast on every critical exposure.
• End-to-end exposure path insights – Practitioners can query their environment by identity attributes, such as service accounts, privileged users, and Active Directory groups, to surface exposure paths that traditional asset inventories miss. Tenable Hexa AI also provides guided assistance for complex Active Directory sensor configurations.

Build your own AI agents for cybersecurity with Tenable Hexa AI

In addition to out-of-the-box agentic capabilities for use cases like automated assessment configuration, asset tagging, and ticket creation, customers can also build custom agents via Tenable Hexa AI’s built-in MCP that are informed by your organization’s unique security policies and internal business logic.

Tenable Hexa AI serves as the orchestration layer connecting your favorite AI tools to your infrastructure and other security tools, all with the data and context from the Tenable Exposure Data Fabric. By anchoring the models your organization uses in the authoritative context of your own environment, Tenable Hexa AI moves you beyond generic AI answers to governed and auditable automation. Whether you are automating complex remediation or generating board-ready dashboards, Tenable Hexa AI ensures the output is both verifiable and auditable.

The Tenable Exposure Data Fabric is key because an agent is only as effective as the data it has access to. Tenable Hexa AI is powered by the Tenable Exposure Data Fabric, a repository of 20 years of vulnerability research and the industry’s largest collection of contextualized exposure data. In other words, we’ve built an agentic engine for cybersecurity that uses the world’s best exposure data to drive machine-speed actions. This is the only way to ensure your AI is validating the real state of your environment, rather than just guessing.

Real-world agentic AI use cases for Tenable Hexa AI 

While there are virtually infinite ways to apply agentic orchestration to your unique cybersecurity challenges, here are four high-impact areas where manual workflows traditionally break down and make it impossible for you to keep pace with AI-powered vulnerability discovery: 

• Supply chain response – Neutralize third-party threats by using Tenable Hexa AI to correlate software components with affected internal assets.

• Automated patching – Use custom Hexa agents to beat the Mythos clock by orchestrating patches the moment a vulnerability is validated.

• Remediation assignment – Use Tenable Hexa AI to automatically match CVEs to asset owners in seconds and trigger immediate response workflows.

These use cases demonstrate how Tenable Hexa AI can bridge the gap between exposure intelligence and action.

Make the untenable Tenable

The collapse of the exploit window is a wake-up call. It gives us the opportunity to change how we work. By shifting from manual triage to agentic orchestration, organizations are seeing a shift in productivity and how they prioritize and action exposure reduction.

While early design partners have already reclaimed days per month on foundational tasks like asset tagging, the value is not found solely in the hours saved, but rather, in the precision of the response. By automating the correlation between cloud, identity, AI, OT, and vulnerability data, Tenable One provides the clear, contextualized instructions that IT and DevOps teams need to act with confidence.

This eliminates the administrative friction and back-and-forth negotiation that often results in critical vulnerabilities going unaddressed. Reclaiming those days means your best people are no longer buried in spreadsheets; they are focused on high-impact strategy, architecture hardening, and preemptive defense.

Tenable Hexa AI is available today as part of the Tenable One Foundation and Tenable One Advanced packages.
