Action Required: Preparation for January 2026 Tenable Security Center Feed Update
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.

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) 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. For a detailed guide on our enhanced VPR, check out this FAQ. Want to see the why behind our scoring? View our scoring explained.Now available: VM-Native OT Discovery

Our latest release, Tenable Security Center 6.8, introduces several new features and enhancements to streamline your security operations: Focus on real risk: Stop chasing 60% of Common Vulnerabilities and Exposures (CVE) as High or Critical. Start focusing on the 3% of CVEs that truly matter. Enhanced VPR logic and new AI-powered insights explain why an exposure is significant and provide clear mitigation guidance based on regional and industry-specific threat actor behavior. Streamlined infrastructure: We’ve unified IPv4, IPv6, and Agent repositories into a single, flexible Asset Repository type to reduce administrative overhead and give you more freedom in how you bucket and analyze your data. You can now target any data, including agent, network scan, and passive data, into any repository. Asset grouping and customization: The Explore Assets page includes new "Group By" options for Microsoft ID, Network, System Type, and Asset Criticality Rating (ACR). Other enhancements to the Explore Assets page include the ability to edit ACR scores (available in Tenable Security Center Plus) directly in the Explore interface. You can also export findings and installed software for specific assets to a comma-separated values (CSV) file. Background queries: Start a query and keep working. Tenable Security Center now processes long-running asset searches in the background. Scan optimization: Prevent performance issues with new per-host timeouts that keep your scan schedules on track to prevent a single host from increasing overall scan time. Enhanced security: Use at-rest encryption for External PostgreSQL databases and expanded PAM integration for Delinea and BeyondTrust. Before you upgrade: Tenable Security Center 6.8 supports upgrades from version 6.4.0 and later.

The April 2026 release of Tenable Patch Management is officially live. This update focuses on the unpatchables—modern ARM architectures, massive Windows feature updates, and performance-heavy drivers—giving you broader coverage without the operational lag. What’s changing and why it matters: Support for the modern cloud (Linux ARM): The value: Organizations are increasingly adopting ARM-based architectures (like AWS Graviton) for better cost and power efficiency. Tenable Patch Management now provides full patch lifecycle management for ARM-based versions of RHEL, Ubuntu, Debian, and more. Use case: If your DevOps team is scaling web-scale applications on ARM-based cloud instances, you can now include these specialized endpoints in your standard autonomous patch strategies, ensuring they receive the same security rigor as your traditional x86 fleet. Zero-friction windows upgrades: The value: We’ve automated the big ones. Windows 10/11 Feature Updates are notoriously difficult to manage due to their size and complexity. Tenable Patch Management now automates the eligibility checks and phased rollouts of these updates, utilizing peer-to-peer distribution to protect your bandwidth. Use case: A security manager can set a policy to roll out the latest Windows 11 Feature Update in waves, starting with a canary group in IT for validation before moving to broader business units, ensuring a smooth transition without disrupting global operations. Lightweight driver patching: The value: We’ve ditched heavy CAB-based catalogs. Get lightning-fast visibility into Dell, HP, and Lenovo drivers using native OS metadata. Use case: You can now perform frequent driver scans across thousands of remote laptops without worrying about "scan bloat" or slowing down employee machines during peak hours. Expanded Linux coverage & platform speed: The value: Stay current with the latest enterprise environments. We’ve added comprehensive support for Amazon Linux 2023 (AL2023), the latest Fedora (42/43) releases, and the newest SUSE and OpenSUSE iterations (including SLES/SLED 15 SP7 & 16). Combined with our migration to Java 25 virtual threads, we’ve slashed the memory footprint for both client and server, making the platform faster and leaner. In addition to all of the new features, we’re also making the following UI enhancements and bug fixes: Patch filter preview: Resolved a bug where multiple filter categories in the Strategy Editor (e.g., Tenable.vpr, risk.cvssscores) failed to return results when using the "Preview Filtered Software" function. Simple preview: Fixed an issue in the Simple Strategy Editor where the "Preview Targeted Patches" button returned empty results for products with a SoftwareProduct parent, including all Windows OS, Linux, and Driver patches. Pre-staging bug: Fixed a critical issue where Windows Update deployments would fail to start if the "pre-staging" option was enabled. Save as API: Resolved a REST API error that occurred when using the "Save As" feature on an existing strategy template. Character limits: Increased the character limit for User Interaction settings text fields (specifically the HTTP POST Message field) to prevent data truncation and database errors. Get the full details This release is available for both Tenable Patch Management SaaS and On-Prem customers.
