Welcome to your monthly round-up of the latest Tenable product updates, platform enhancements, and community news. This month, we’re bringing frontier AI reasoning into exposure management, deepening cloud and vulnerability visibility, and expanding how the community vets AI agents before deployment.

Tenable One - Platform updates

Claude Mythos 5 is coming to Tenable One with Adversary View

Attackers don’t exploit systems in isolation. They chain together scattered, low-signal evidence like netstat entries, cached accounts, and active connections that traditional rules engines can’t connect, and that your team doesn’t have time to piece together manually. 

This is where frontier AI models shine. Tenable One Adversary View, launching this September, brings the power of Anthropic’s Claude Mythos 5 directly into the Tenable One Exposure Management Platform. Built on the Project Glasswing collaboration between Tenable and Anthropic, Adversary View applies advanced cyber reasoning to your existing exposure data, uncovering hidden vulnerability chains, visualizing how an attacker would actually move through your environment, and surfacing evidence-backed fixes to break those chains before attackers exploit them — all within an agentic harness that keeps the AI’s reasoning controlled and auditable.

• Take advantage of Claude Mythos 5 to tackle complex exposure management challenges.
• Cut through the noise with a ranked, prioritized list of the vulnerability chains that matter most, backed by evidence and specific remediation guidance.
• Move at the speed of adversaries by pairing Claude Mythos 5’s advanced reasoning with the exposure intelligence you already have in Tenable One — no new tools required.

3 new connectors bring GitHub and GitLab findings into Tenable One

Tenable One connectors combine your third-party security tools with Tenable’s native sensor data for one view of risk across your attack surface. Three new connectors extend that coverage, pulling static application security testing (SAST), software composition analysis (SCA), and secret scanning findings straight into Tenable One.

• GitHub Code Scanning: Consolidates SAST and secret scanning findings, covering both vulnerable code and exposed credentials, into the same risk view as every other exposure you track.
• GitHub Dependabot: Brings SCA alerts on vulnerable dependencies, so a flawed package deep in your supply chain gets prioritized against everything else exposing you.
• GitLab Connector: Covers SAST, SCA, and Secret Detection findings in one connector, consolidating what’s otherwise split across multiple tools into a single risk view. Requires GitLab Ultimate to ingest findings.

All three are native connectors; add the connector, and findings start showing up in Tenable One.

CyberAgents Exchange

Exchange Inspector vets AI agents before they reach your environment

Tenable and OpenAI unveiled the CyberAgents Exchange AI Inspector, which pairs OpenAI’s GPT cyber models with Tenable One AI Exposure and expert researcher review to screen AI agents, skills, MCP servers, and multi-agent playbooks for prompt injection, PII exposure, and supply-chain risks before they’re deployed.

• Combines OpenAI GPT cyber models, Tenable One AI Exposure, and expert researcher review to vet AI agents before deployment.
• Screens AI agents, skills, MCP servers, and multi-agent playbooks for prompt injection, PII exposure, and supply-chain risks.
• Gives practitioners insight into production-ready AI agents and CISOs the confidence to approve their use.

The Exchange Inspector builds on the CyberAgents Exchange registry, which has already drawn more than 100 AI listings. Exchange Inspector is expected to be available in September.

Tenable One Vulnerability Management

Visualize your security trends over time

You can finally see exactly where your security metrics are heading, not just where they stand today. With newly added Trending Widgets, you can track your asset data and findings as daily line charts, giving you the historical context you need to accurately monitor your progress.

Data collection begins the moment you set up a widget. To get started, you can:

• Build custom views: Add up to five unique trend lines per widget, tailoring the dataset, entity type, and filters for each.
• Deploy pre-built charts: Search trending in the widget library to drop ready-to-use visualizations right onto your dashboard.

Tenable One Cloud Exposure

Expanded Kubernetes and container topology in Tenable One Cloud Exposure

A comprehensive overview of Kubernetes and container topology is essential for risk-based prioritization because you have to see the whole picture of the resources, workloads, and clusters a vulnerability touches to know what’s actually risky. 

Now, the “graph” tab in Tenable One Cloud Exposure gives you the full structural layout of a Kubernetes cluster, all the way down to a vulnerable container image, in one interactive view.

What’s new:

• Guided relationship picker: By expanding any node in the graph, it now surfaces a categorized menu (Compute, IAM, Kubernetes, Containers, Management, Network, Risk) so you can choose which connection to explore next.
• Full Kubernetes depth: Namespaces, roles, role bindings, service accounts, configuration maps, and workloads all surface as first-class nodes, whether the cluster is EKS, AKS, GKE, or self-managed.

The Kubernetes graph provides a holistic view of cluster contents, namespaces, and resource relationships, while allowing you to effortlessly navigate from clusters to underlying virtual machines and specific workloads, such as business-critical services. It also enables you to explore vulnerability instances linked to container images, ensuring they have complete context for risk prioritization and informed decision-making.

Tenable Nessus

Nessus reliability and performance updates

We have released several Tenable Nessus updates recently, with a mix of new capabilities as well as improvements related to performance and security.

• Scanner reliability fixes: Resolved SSL connection issues that could cause scanners to appear offline and stop receiving plugin updates.
• Kerberos authentication fix: Corrected an issue blocking plugins from retrieving host FQDNs, causing authentication failures.
• Tenable Security Center performance: Fixed timeout errors when processing large volumes of Tenable Nessus agent reports.
• Certificate handling: Resolved an issue in PostgreSQL client authentication.
