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.

We are writing to announce an important upcoming change to the Tenable Security Center feed data. Starting in mid-January 2026, the size of Tenable Security Center feeds will increase due to the addition of new Vulnerability Priority Rating (VPR) data; this data will be available in Tenable Security Center 6.8, anticipated for release later in Q1 2026. This update ensures you continue to receive comprehensive vulnerability data, but it requires immediate action to ensure your environment is prepared. What you need to do To prevent the feed size from causing PHP memory exhaustion in your environment, please follow the resolution path for your specific version: Versions 6.5.1 – 6.7.2: Patch 202601.1 is now available. Applying this patch will automatically modify the PHP configuration to increase the memory limit. Versions Prior to 6.5.1: Follow the instructions outlined in this Knowledge Base article to modify the PHP configuration. Note: Tenable Security Center consoles with less than 8 GB RAM may need to have their hardware resources updated. Review Tenable Security Center hardware recommendations Why this matters Taking action now allows you to adopt a proactive approach to this feed expansion, ensuring your nightly updates continue seamlessly. Prevent SC Feed Update Failures: Without this fix, SC Feed updates may fail and log an "Allowed memory size... exhausted" error or terminate abnormally with error status '255'. Protect Disk Space: Failing feed updates can leave behind orphaned files in /opt/sc/data/feed.XXXXX folders, which may build up and cause disk space issues over time. Access our related documentation to learn more: Tenable Security Center Patch 202601.1 (2026-01-06) Knowledge Base: Tenable Security Center Feed Update Failing with "terminated abnormally with error status '255'" Due to PHP Memory ExhaustionIntroducing Enhancements to VPR in Tenable Vulnerability Management!
Today, we launched enhancements to Vulnerability Priority Rating (VPR) in Tenable Vulnerability Management. These updates provide unmatched precision, AI-driven insights, and contextual understanding to help your security teams prioritize and remediate vulnerabilities more efficiently. How this benefits you: Sharpen precision to focus on what matters most: While traditional CVSS scores classify 60% of CVEs as High or Critical, our original VPR reduced this to 3%. The enhanced VPR further refines this, helping your teams focus on just 1.6% of vulnerabilities that represent actual risk to your business. This is achieved by leveraging an even broader spectrum of threat intelligence and real-time data input used to predict near-term exploitation in the wild. Unlock AI-driven insights and explainability: Our new LLM-powered insights deliver instant clarity, helping you quickly understand why an exposure matters, how it has been weaponized by threat actors, and providing clear, actionable guidance for mitigation and risk reduction. Prioritize with industry and regional context: New metadata provides crucial context, helping you understand if a vulnerability is being targeted in your specific industry or geographic region. Leverage advanced querying & filtering: The enhanced VPR model is easily accessible for filtering and querying in the new Explore views, which display Assets and Findings data, enabling faster investigations and response workflows. Both the original VPR and the enhanced VPR (referred to in-product as 'VPR (Beta)') will coexist for a period of time in Tenable Vulnerability Management, ensuring you can make a smooth transition. Future deprecation of the original VPR will be communicated in advance. To learn more about the enhancements to VPR, see the solution overview and click-through demo.
