Tenable Product Update Newsletter — July 2026
Check out our July newsletter to learn about the latest product and research updates, events, and educational content. Plus, this month we’re featuring the launch of the CyberAgents Exchange, powered by Tenable. Keep reading to read more about the new open-source AI exchange! Tenable One - Platform updates Integrate application security data into Tenable One for code-to-runtime security Your codebase is growing faster than your security program, and in the age of AI, developers are introducing security findings at 10 times the rate of their peers. It is critical to see code as part of your entire attack surface. Application security data now integrates directly into Tenable One to further close visibility gaps and ensure secure code development in the AI era. Whether code is human- or machine-written, you can now integrate application security risks, like those from Snyk, Claude Security, or any other application security tool via Tenable One Connectors — directly alongside your existing exposure data. What this means for you: Achieve full code-to-runtime visibility by bringing application security risks together with the rest of your exposure data in one place. Fix code flaws before they become incidents by identifying your most business-critical code flaws and fixing them early in the development lifecycle. Measure organizational exposure and transform technical static code vulnerabilities into clear risk metrics on business resilience. Read the blog post Explore the guided demo Check out Open Connector documentation and Snyk Connector documentation Improved workflow orchestration capabilities in Tenable One Vulnerability Management and Tenable One New enhancements to Tenable's workflow orchestration capabilities are now generally available. This release streamlines remediation workflows and improves operational efficiency with the following key updates: Plugin output in tickets: You can now attach Plugin Output directly to tickets, providing immediate context and critical information while eliminating the need for further navigation. Tenable Hexa AI for ServiceNow: You can now leverage Tenable Hexa AI for ServiceNow incident and initiative creation to match already available Jira functionality. Review the exposure management release notes Review the Tenable Vulnerability Management release notes Tenable unified scoring is now live Tenable has unified its risk prioritization standard, moving the high-fidelity Vulnerability Priority Rating (VPR) model out of beta to become the sole standard. To sharpen your prioritization, an updated asset classification engine also delivers more accurate Asset Criticality Ratings (ACR) for your assets. Because VPR and ACR feed directly into your Cyber Exposure Score (CES) and Asset Exposure Score (AES), your console will automatically update to reflect a precise understanding of your exposure. These recalculations occur automatically, though completion times depend on the size of your environment. To prevent errors in your saved views, you must manually update any filters or combinations that still use VPR v1. No data migration is required.

Research Release Highlight – "Fully Scan Operational Technology" Default Setting Change
Summary The "Fully Scan Operational Technology" (OT) preference controls whether Nessus actively scans OT/ICS devices during a scan. This setting is intended to be disabled by default to avoid unintended disruption to sensitive operational technology environments. A long-standing setting in the Do not scan operational technology devices plugin caused this preference to default to enabled in a Basic Network Scan when the discovery type is not set to Custom. Change The default value for "Fully Scan Operational Technology" preference has been corrected from yes to no. Impact This fix will affect existing Basic Network scans automatically upon the next feed update — no scan recreation is required. Customers using Basic Network Scan policies with a non-custom discovery scan type will see the following behavioral change: Before change: "Fully Scan Operational Technology" was silently enabled, meaning OT devices may have been actively scanned. After change: "Fully Scan Operational Technology" will correctly default to disabled. Customers who intentionally want to scan OT devices should explicitly enable the "Fully Scan Operational Technology" preference by switching their scan policy's discovery type to Custom, which will expose the preference in the UI and allow it to be toggled on. Affected products: Tenable Security Center (SC), Tenable Vulnerability Management (TVM), and Nessus Target Release Date July 13, 2026
Tenable product update: Standardizing Tenable risk scoring
At Tenable, we are committed to providing the most accurate, defensible, and actionable view of organizational risk. To achieve this, we must continually refine the intelligence that powers your prioritization. On July 1, 2026, we are implementing a series of foundational updates to our risk scoring engines. As part of this update, you may see changes to your risk scores, depending on the Tenable product(s) you own. These changes simplify your workflow by standardizing scoring on a single, high-fidelity model for vulnerability and asset risk. The new standard for VPR For the past several months, many of you have utilized VPR (Beta) to gain deeper insights into exploitability. We are excited to announce that on July 1, this model will be promoted to the primary Vulnerability Priority Rating (VPR) across the Tenable platform. By standardizing on this advanced model, we are retiring legacy VPR scoring to ensure every customer benefits from our most sophisticated threat intelligence. The new version of VPR incorporates more threat intelligence and vulnerability metadata so that you can focus on the 1.6% of vulnerabilities that actually matter. Better context through enhanced asset classification Alongside the VPR update, we are enhancing our asset classification engine. This update improves how we identify the function and importance of assets across your entire attack surface, including Cloud, OT, and third-party devices. As a result, customers with access to Asset Criticality Ratings (ACR) for VM assets will see these scores more accurately reflect real-world business risk. What this means for you These are backend enhancements designed to provide immediate value with zero manual configuration. On July 1, your dashboards, reports, and APIs will automatically reflect these updated metrics. Because both VPR and ACR serve as inputs to Cyber Exposure Score (CES) and Asset Exposure Score (AES), customers using these scores may see changes that reflect a more accurate understanding of exposure. Customer FAQ What happens to the VPR (Beta) score in the Tenable UI? The Beta label will be removed. The high-fidelity model you’ve been previewing will become the standard VPR. The legacy version of VPR will be retired to ensure a single, unified source or truth. Do I need to rewrite my custom API scripts using VPR? No. For customers using APIs, updated values will be mapped into legacy VPR fields on the back end to ensure compatibility and a smooth transition for your scripts and third-party tools. How does this affect my SLAs? Because many organizations use VPR as their operational prioritization layer, your SLA statistics and remediation tracking will now reflect the more precise scoring model. This helps ensure your team is meeting response goals for the vulnerabilities that pose the highest actual risk. How does Enhanced Asset Classification affect my scores? The system now automatically identifies the function and criticality of assets across Cloud, OT, and third-party sources. This improved context leads to more accurate Asset Criticality Rating (ACR) adjustments. For customers with access to ACR, this ensures your most critical business assets are effectively prioritized. What actions does my team need to take, and when will the changes be reflected in my container? These updates will occur automatically within your Tenable console. Depending on the size of your environment, it may take time for score recalculations to be fully reflected across your console. For a detailed guide on our enhanced VPR, check out this FAQ.

Improvement to Printer OS Fingerprinting
Updated: April 3, 2026 Summary Scanned printers will now have an OS artefact surfaced in their scan host metadata if the target has been identified as a printer when the “Scan Network Printers” policy option is disabled. This change will not cause any additional asset licenses to be consumed within Tenable VM or Tenable Security Center. Background Printers are notoriously unstable scan targets. Oftentimes, they can behave erratically when scanned, so some users prefer to avoid scanning them altogether. At present, there is a switch in the scan policies to prevent further scanning of a host when it's identified as a printer. To enable this setting, go to Settings -> Host Discovery -> Fragile devices - Scan Network Printers (Currently, this is a checkbox setting, default value “off”). With that said, how can the scanner know the target is a printer if it cannot be scanned? In reality, the scanner still performs very basic fingerprinting (usually via SNMP) in order to gather enough information to make an educated guess at the device type. When the scan target is thought to be a printer, it essentially gets marked as “Host/dead" in the scan KB. When this happens, the scanner will not perform any further active scanning. Changes With this update, the fingerprint used to identify the printer as such, will now be stored in the scan Knowledge Base (KB) so it can be processed by os_fingerprint2.nasl ("Post-scan OS Identification", plugin ID 83349) and surfaced as metadata in the scan result. The relevant policy setting located at Settings -> Host Discovery -> Fragile devices -> Scan Network Printers. With this update, the printer's OS information will now be surfaced if it is available, regardless of the selected value for this setting. Impact Users can now see the OS information for their printer devices that would have otherwise gone unreported if the scan is not configured to “Scan Network Printers”. As plugin ID 83349 generates no plugin output, only an “operating-system” tag will be added to the scan result (and stored in an exported .nessus file). This information will be visible only the in “Host/Asset Details” section of the Tenable product UI, i.e: Tenable Nessus: Scans -> [Folder] -> [Individual Scan Result] - > Host Details -> OS (sidebar) Tenable Vulnerability Management: Explore -> Assets -> [Asset] -> Details -> Operating System Scans -> Vulnerability Management Scans -> [Individual Scan Result] -> Scan Details -> Asset Details -> Operating System Tenable Security Center: Analysis -> IP Summary -> [IP address] -> System Information -> OS Scans -> Scan Results -> [Individual Scan Result] -> IP Summary -> [IP address] -> System Information -> OS Note, we expect this information to surface mainly in individual scan results. It would only be present in cumulative asset details if a licensed asset already exists for the target in question. This update will not cause additional assets to be created or consume any additional licenses. Affected Plugins 83349 - os_fingerprint2.nasl 11933 - dont_scan_printers.nasl 22481 - dont_scan_settings.nasl Targeted Release Date Wednesday, March 4, 2026
