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.

Tenable Post-Quantum Cryptography Inventory Support
Summary The advent of quantum computing presents a significant threat to current cryptographic algorithms. Organizations worldwide are beginning the critical transition to post-quantum cryptography (PQC) resistant algorithms to ensure long-term data security. Government mandates, such as the U.S. National Security Memorandum 10 (NSM-10), outlines deadlines for PQC migration and specific actions agencies must take to migrate vulnerable systems. Our PQC support is designed to help customers inventory use of TLS and SSH quantum-resistant and vulnerable algorithms within their infrastructure using remote Nessus-based scans. Cipher Inventory and Reporting Post-Quantum Cipher Plugins Two remote-based scan informational reporting plugins for TLS and SSH protocols inform customers of their transition posture according to NIST Post-Quantum Encryption Standards. Services Using Post Quantum Cryptography: Reports on services equipped with at least one post-quantum cipher. It will specify which post-quantum ciphers were discovered, reporting by port and protocol. Services Not Using Post Quantum Cryptography: Reports on services that support no post-quantum ciphers. These plugins will be enabled by default and included in existing scans. Cryptographic Inventory Plugin Reporting To enable a JSON-based inventory of each target by service and cipher, enable through either a preference on your Advanced Network Scan or by running the Cryptographic Inventory scan template. These preferences will initially be supported in Nessus and Tenable Vulnerability Management. They are planned to be added to Tenable Security Center at a later date. Warning: Enabling this preference through the Advanced Network Scan is expected to increase the overall size of the plugin output per target and resulting Nessus database size. If you do not need to produce this inventory at all or on your regular scan cadence, it’s recommended to instead run the Cryptographic Inventory scan template to decrease the potential impact to your normal scan results. Options to Enable Inventory Reporting Advanced Scan Preference Post Quantum Cryptography Scan Template Cryptographic Inventory Plugin Details The plugin enabled with the preference or scan template is an information plugin called Target Cipher Inventory. Within the output of this plugin, you will find a JSON structure containing the TLS and SSH inventories for the scanned target. You can export this inventory based on plugin output using the Tenable API if needed. For TLS, the structure contains: Attribute Definition Encaps Protocol encapsulation employed such as TLSv1, TLSv2, TLSv3 Port Port used for TLS communication Curve Group Encryption method Ciphersuite Algorithm used to secure the TLS connection For SSH, the structure contains: Attribute Definition Proto Protocol of SSH Port Port used for SSH communication Name Algorithm used to secure the protocol Type Use of the named algorithm such as “message auth” Release Date Tenable Vulnerability Management and Tenable Nessus: December 8, 2025 Tenable Security Center: - December 8, 2025 for the informational plugins - Cryptographic Inventory scan template release to be determined
Improvement: Handling Component Installs for Vulnerability Assessment
Background On Friday, February 6, 2026, Tenable Research published a plugin update that changed the way component installs are assessed for vulnerabilities. Those changes are outlined in a previous release highlight: Component Installs Require Paranoid Checks, This update essentially reverts this change, while adding new functionality to allow users to choose whether or not they want component installs assessed for vulnerabilities. Component installs are no longer influenced by scan paranoia settings. What are “Component Installs”? Software components, such as applications or language modules/libraries, are installed and managed by a primary "parent" package or application. The crucial point is that these components often cannot be updated individually. Instead, their vulnerability assessment and upgrade are entirely dependent on an update of the parent package. For instance, the SQLite database component is installed as part of the Trend Micro Deep Security Agent and is updated only when the Agent itself is updated. Nessus uses several factors to determine if a detected product is a component, or a standalone installation, including: Was the product installed by a package manager? These products are not considered components, as they are managed by the package manager and not a “parent” application Is the component a “language library”, i.e. a library or module used by the interpreter of a programming language like Python or Node.js? These enumerated libraries are marked as components by default. Does the product reside in a directory that is recognized for installations that are not component-based? Changes By default, component installs are once again assessed for vulnerabilities, as was the case prior to the release of the aforementioned update. If users wish to turn this setting off, so that component installs will not be assessed by generic vulnerability detection plugins, they can do so via the newly created scan preference. The end result of this change should be that fewer “false positives”, i.e. reported vulnerabilities for components that are “owned” by another application, are shown in scan results. Components with vulnerabilities that cannot be addressed independently of the “parent” application will not show in scan results. However, some customers have expressed a desire to see these vulnerabilities in their scan results anyway, to ensure full awareness of the risk profile of every application in their environment. This is still possible through the updated scan configuration settings. To modify this setting in your scan policy, go to Settings > Assessment > Accuracy > Override Normal Accuracy > Assess component installs for potential vulnerabilities. This setting is ON (checkbox is ticked) by default, so users must enable the Override Normal Accuracy checkbox (which is OFF / unchecked by default) if they wish to disable the setting and ensure that component installs are not assessed by generic vulnerability detection plugins in this scan. Please note that this update makes no other changes to the existing paranoia logic, outside of what is described above. For now, “Managed”, “Managed by OS” and “Backported” installs are still controlled by the Show/Avoid potential false alarms radio button. How can I tell if the detected install is a component or not? In addition to the above, we have also updated the relevant detection plugins so they will show if the component flag is set or not. At present, this includes detection plugins for OpenSSL, Curl, LibCurl, Apache HTTPD, Apache Tomcat, SQLite, Python Packages, Node.js modules and, soon to follow, Ruby and Nuget libraries. Using plugin ID 174788, SQLite Detection (Windows), here is a before and after example of the expected plugin output. Before: After: Expected Impact With the new default setting in place, users should anticipate an increase in vulnerability findings for the products in scope, returning to a level similar to what was observed before the first update. If users do not wish to surface these additional potential vulnerabilities, they should disable the "Assess component installs for potential vulnerabilities” setting. If the new scan preference is disabled, the volume of findings will remain consistent with current levels, when scanning with normal accuracy (paranoia) settings. Affected Plugins 12288, global_settings.nasl (updated to support the new scan policy preference) Any plugin that operates downstream of those in the list below: SQLite: 174788 - sqlite_nix_installed.nasl 171077 - sqlite_win_installed.nasl OpenSSL: 168007 - openssl_nix_installed.nasl 168149 - openssl_win_installed.nasl Curl: 182774 - curl_nix_installed.nasl 171860 - curl_win_installed.nasl LibCurl: 182848 - libcurl_nix_installed.nasl Apache HTTPD: 141394 - apache_http_server_nix_installed.nasl 141262 - apache_httpd_win_installed.nasl Apache Tomcat: 130175 - apache_tomcat_nix_installed.nasl 130590 - tomcat_win_installed.nasl Python Packages: 164122 - python_packages_installed_nix.nasl 139241 - python_win_installed.nasl Node.js Modules: 178772 - nodejs_modules_linux_installed.nasl 179440 - nodejs_modules_mac_installed.nasl 200172 - nodejs_modules_win_installed.nasl Targeted Release Date Tenable Nessus and Vulnerability Management: Monday, March 9, 2026 (ETA 22:30 Eastern Standard Time) Tenable Security Center: Monday, March 16, 2026Improvement 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, 2026Now available: VM-Native OT Discovery

View full cloud release notes Tenable Identity Exposure This month, we are focusing on removing deployment friction for indicators of attack (IoA). To maintain a high-velocity security posture, we have simplified the process of authorizing installation scripts within your existing EDR/AV environments. Frictionless IoA deployment: We’ve added three new parameters to the IoA installation script to ensure your security stack works in harmony. This enhancement accelerates time-to-protection by pre-authorizing deployment scripts and preventing false-positive blocks from security tools. Proactive authorization: Use OutputCertificate or GetSignatureToWhitelist to retrieve the Tenable certificate or script hash for immediate allowlisting. Controlled execution: The TimerInMinutes parameter allows you to delay installation, ensuring your environment has processed allowlist updates before the script runs. View full identity release notes By focusing on these specific parameters, your team can avoid the manual overhead of troubleshooting blocked installations and move directly to monitoring for identity-based threats.
