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.

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

Tenable Identity Exposure Tenable’s Research-Driven Identity Defense Expands Tenable continues to deepen its coverage of real-world identity risks with a series of new indicators of exposure (IoEs) across both Active Directory (AD) and Entra ID. BadSuccessor—a rare, but forest-level critical, zero-day privilege escalation vulnerability in AD, was recently disclosed. Introduced with delegated Managed Service Accounts (dMSAs) in Windows Server 2025, its exposure depends on the presence of a 2025 domain controller, but the impact can be severe. An attacker with the right permissions could use a dMSA to inherit domain admin-level access and compromise the entire forest. Tenable has responded quickly with a dedicated IoE: BadSuccessor – Dangerous dMSA Permissions, now available in Tenable Identity Exposure (SaaS) v3.95. This detection flags risky dMSA inheritance paths that could enable exploitation, helping organizations stay ahead even in the absence of a Microsoft patch. Review Tenable’s technical advisory and FAQ for detailed context. More IoEs targeting real-world risk Other new IoEs target misconfigurations and gaps attackers routinely exploit, spanning Tier 0 risks in AD and hygiene issues in Entra ID. Each IoE is designed to be practical, observable and relevant, shaped by real attack behaviors, not just theoretical risks. Check out this product documentation for more information. Active Directory Tenable IoE “Sensitive Exchange Group Members” Who really sits in the most privileged Exchange groups: a Tier‑0 foothold. Tenable IoE “Exchange Permissions” Risky ACLs where Exchange rights bleed into domain control. Entra ID Tenable IoE “Users Allowed to Join Devices” Tenant setting that lets any user enroll a rogue workstation. Tenable IoE “Managed Devices Not Required for Auth” Conditional‑access gap allowing unmanaged logins. Tenable IoE “Auth‑Methods Migration Incomplete” Legacy authentication policy is still exposed. Tenable IoE “Dangerous Application Permissions” Third‑party app scopes that can exfiltrate data. Tenable IoE “Risky Users Without Enforcement” Risk‑based access policy missing for high‑risk accounts. Tenable Cloud Security Reminder: Tenable Cloud Security requires you to log in to view documentation. To access the documentation or try Tenable Cloud Security, contact your account manager or request a demo. Enhanced CVE detection and customizable severity metrics Tenable Cloud Security now enhances CVE detection by integrating Tenable's vulnerability logic, leveraging the Tenable vulnerability data lake (TVDL) and Nessus. This improves accuracy and coverage in detecting new CVEs regardless of National Vulnerability Database (NVD) delays. The integration aligns CVE detection between Tenable Cloud Security and Tenable Vulnerability Management, reducing inconsistencies and boosting reliability within Tenable One. Users can select which CVE severity metric to display first: CVSS (static) or VPR (dynamic, factoring exploit likelihood). The metric chosen as primary impacts finding creation: severity changes can cause related findings to open or close. Just-in-time by resource groups and recurring access Thanks to your feedback, Just-in-Time (JIT) access is now even more powerful and flexible. Azure users can request access at the resource group level, not just by subscription, giving you greater granularity and control across your cloud environments. And for all JIT users, building on existing immediate/scheduled access request support, we’ve added recurring access scheduling — to better support business workflows, such as a contractor needing project access for a specified repeat duration or the need for access to a routine audit that lasts a full quarter. Easily set daily, weekly or monthly schedules with end dates — all through an intuitive UI. Consider using recurring access to replace standing permissions that some JIT users may still have, for more granular time-bound least privilege. Powerful Tenable cloud vulnerability insights within ServiceNow Tenable now integrates with ServiceNow’s new Vulnerability Response platform, enabling you to seamlessly import prioritized, actionable vulnerability data directly into ServiceNow. This streamlined integration, which also supports government environments, helps teams focus on what matters most by aligning Tenable findings with your existing remediation workflows, making it easier to act fast on critical risks. Already using ServiceNow ticketing? You can now sync Tenable findings with ServiceNow incidents, mapping severity and status to priority and state (such as open findings to new incidents). Note: Syncing incident states requires additional permissions and configuration within ServiceNow. Selectively scan data resources by exclusion tags You can now add exclusion tags to fine-tune scans of both managed databases and object storage in Tenable Cloud Security. Exclusion tags enable you to scope out resources starting from the next scanning cycle by specifying tags as configured at the resource level, for tailoring scans to your environment. This new capability helps you decrease costs by reducing unnecessary resource usage. Object storage comes to OCI As part of our growing capabilities around Oracle Cloud, Tenable Cloud Security now offers data analysis of object storage buckets in OCI. Out of the box, the feature is on a par with all other object storage that Tenable Cloud Security supports and is part of routine CSPM onboarding. In other updates, new dynamic scan scoping by tag is also supported for OCI. Tenable Vulnerability Management (TVM) Tenable Data Stream (TDS) now supports the streaming of TVM Host Audit Findings data as well as WAS assets, tags and findings data. TDS already supports TVM host assets, tags and vulnerabilities data streaming to AWS S3 buckets and is used by some of the largest TVM customers. Learn more about TDS here. Besides the new payloads, there are a few more improvements: Additional new fields in TVM findings payload like Resurfaced Data and Time Taken to Fix Grouping of the files written in the AWS S3 buckets is now based on timestamp, resulting in fewer files written, which in turn improves consumption and reduces latency. (Previously, this was based on both scan ID and timestamp, which resulted in writing a large number of small files.) Tenable Patch Management Tenable Patch Management now supports Red Hat Enterprise Linux (RHEL) We’re excited to announce that Tenable Patch Management (On-Prem) 9.2.967.20 now supports RHEL 8 and RHEL 9. This release also includes performance improvements, bug fixes, and an important security update to Java 17 JRE. Please note that Patch Notification Bots using WhatsApp require review and modification as they can no longer be combined with other providers. Please visit here for a list of third-party applications covered. Note: We are always adding more. For more information, please read the Tenable Documentation and Release Notes and visit the Downloads Portal for the latest version. Tenable OT Security Upgrade to Tenable OT Security 4.2 to unlock new layers of visibility across your OT/IT environment. Key enhancements in this release include: Advanced SNMP-based asset discovery: Gain deeper OT network topology insight. Our new SNMP Crawler discovers and maps all connected devices and switches, including previously hidden ones, down to the specific switch port.

This powerful new visualization acts as a command center for security teams to quickly prioritize and address the most critical identity threats. What’s included: Top Risk & Exposure Signals widgets: These widgets surface the most severe indicators of exposure (IOEs) and aggregated risk scenarios using prebuilt insights and custom queries via ExposureAI. Historical risk trends: Track recurring risks over time, identify resurfaced threats, and demonstrate security improvements. Identity demographics: Visualize risk across privileged, service or dormant accounts to better prioritize protection efforts. Fast-action remediation: Use the "If You Only Have 5 Minutes" widget to jump into the most urgent findings. Exportable reports: Generate professional-grade reports with one click to support audits and stakeholder communications. With Insights, security teams move from fragmented data to an actionable overview — saving time, reducing risk, and improving security posture.

Tenable customers can use their existing (or future) Tenable Cloud Security license to enable and use JIT – with no separate procurement needed! JIT is automatically included with all existing licenses: Enterprise, Standard and CIEM. JIT eliminates standing permissions and reduces cloud risk with on-demand, time-bound access to cloud accounts and identity provider (IdP) groups. See the demo and explore use cases to understand how JIT works and streamlines approvals including by integrating with collaboration platforms like Slack and Microsoft Teams. Unified search and in-product documentation—directly in the Console. Tenable Cloud Security now offers context-aware guidance in the Console, making it easier to find what you need. Queries in the search bar return results across all resources, policies, pages, documentation, and vulnerabilities. In-product documentation is now also accessible directly in the Console through unified search and contextual help links, providing context-aware guidance where you need it. See the documentation for more details. Define projects by resource tags and Azure resource groups. Building on the Projects feature announced in the March 2025 newsletter, Tenable Cloud Security now enables you to scope projects using resource tags (across all Tenable-supported cloud providers) and Azure resource group name patterns. This enhancement provides greater flexibility and granularity in organizing projects based on how your cloud environments are structured: by team, business function, or application boundary. The evolving Projects capability supports stronger cloud security maturity by reducing fragmented visibility and siloed inventories, with dedicated views of resources and security findings, and project-specific dashboards for each team. See the documentation for more details. Enhanced CVSS scoring support with CVSS v4 priority. When multiple CVSS versions are available for a vulnerability, CVSS v4 is prioritized to ensure the severity assessment is the most current and precise. It offers improved accuracy, flexibility, and contextual awareness, enabling better prioritization and automation than CVSS v3. Enhanced 3rd-party support for Microsoft Entra ID apps. Tenable now offers greater IAM visibility for Azure users through enhanced Microsoft Entra ID third-party application mapping, with support for more than 350 applications. From the third-party widget in the IAM Dashboard, you can select a vendor per cloud component and navigate directly to the Identity Intelligence page, filtered by that vendor. You can also now view vendor details for each application in the Microsoft Entra ID Application Inventory page, making it easier to manage third-party applications across your environment. >> To read the rest of the May newsletter, click here.
