SNMPv3 for CyberArk and HashiCorp Vault
Summary Tenable is pleased to announce the addition of SNMPv3 credentials for our CyberArk and HashiCorp Vault integrations. Scope Customers utilizing Tenable Vulnerability Management and Nessus Manager now have the capability to configure vulnerability scans with SNMPv3 credentials for our CyberArk and HashiCorp Vault integrations. This option is situated under the "Host" category within the credentials tab of either the CyberArk or HashiCorp Vault Integration. Detailed information about the integration configurations can be found within our integration documentation pages for CyberArk and HashiCorp Vault. Supported PAM Integrations in this Release: CyberArk HashiCorp Vault Plugins The following integration plugins contain information that is essential for validation whether the integration successfully obtained a credential for use in SNMPv3 authentication. Integration Plugins Integration Status Debugging Log Report Impact Customers will now see CyberArk and HashiCorp Vault as credential PAM options within the SNMPv3 authentication credentials. For any issues related to the use of PAM authentication with SNMPv3, please refer to the new log in the Debugging Log Report. Example: If using SNMPv3 with CyberArk support, the file will display as “snmp_settings.nasl~CyberArk”. Release Date January 7th, 2026 for Tenable VM and Nessus TBD: Tenable Security Center
Research Release Highlight - SSH Session Reuse
Summary Nessus scan will support an opt-in feature to reuse SSH sessions during a scan where possible when running Nessus versions 10.9.0 and greater. This update was made in response to numerous customer requests for reducing the number of new SSH connections established during remote network scans and the associated increase in network traffic. Change A new scan configuration template option will be available for customers to actively enable the [Reuse SSH connections] configuration in their scan policies in Advanced Settings under Advanced Performance Options. Customers can return to the classic SSH connection functionality by changing [Reuse SSH connections] to the default “off” setting in their scan policies. Customers must be running a version of Nessus 10.9.0 or greater that supports this feature and have a Plugin Feed that displays the scan configuration policy user interface and NASL plugin set with the SSH session reuse functionality. Impact Customers should see a significant decrease in the total number of SSH sessions established during a Nessus scan as well as a reduction in load on Enterprise authorization, access, and accounting (AAA) tooling such as RADIUS servers and other connection management services. There should be no difference in scan results between scans that leverage SSH Session Reuse and scans that do not. If customers experience any such issues, the feature can easily be toggled off to return SSH connections during scans to the classic connection functionality. Target Release Date January 15, 2026
Improved Resource Management Control
Summary Improved resource management control for plugins leveraging Windows Management Instrumentation (WMI) on Nessus Agent 11.1.0 or higher. Impact Customers with Nessus Agent 11.1.0 and later versions will have the ability to granularly control the CPU resources consumed during scans. This update ensures that plugins respect the resource usage setting selected during scan configuration by launching commands as children of the Nessus Agent, rather than invoking them via WMI. The release of these plugins will continue through January, with a phased approach over three weeks. The first release will be January 13th, the second January 20th, and the final planned plugin update on January 27th. Target Release Date Phase 1 plugin set: January 13, 2025 Phase 2 plugin set: January 20, 2025 Phase 3 plugin set: January 27, 2025Distinct Agent Plugin Databases for RPM-Based Distributions
Summary Tenable will now provide separate agent plugin databases for RPM-based Linux distributions. Impact Historically, the majority of plugins for RPM-based Linux distributions have all been distributed via a single artifact. Starting with Nessus Agent 11.1.0, Tenable will now publish separate artifacts based on the following plugin families: Alma Linux Local Security Checks CentOS Local Security Checks Miracle Linux Local Security Checks Oracle Linux Local Security Checks Red Hat Enterprise Linux Local Security Checks Rocky Linux Local Security Checks As a result, customers will see a reduction in the overall size of the agent database (15-31% reduction at rest, 7-14% downloaded), directly leading to smaller updates and reduced resource consumption during the update process. This improvement will be available to all customers using Agent 11.1.0 or later versions. Target Release Date January 13, 2026Research Highlight - New Plugin Family: Miracle Linux Local Security Checks
Summary Tenable will now provide vulnerability check plugins for Miracle Linux. Impact Customers with Miracle Linux systems in their environments will be able to scan them for vulnerabilities. These plugins will belong to the “Miracle Linux Local Security Checks” family. At initial release, there will be approximately 1,500 new plugins for Miracle Linux. Use of these plugins will require Agent 11.1.0 and above. Target Release Date January 13, 2026New CyberArk Secrets Manager PAM Integration
Summary Tenable is proud to announce integration with the CyberArk Secrets Manager solution. This integration gathers credentials from the CyberArk Secrets Manager to be used for target authentication. The integration will be available in Tenable Vulnerability Management and Nessus Manager, with plans to release this feature in Tenable.SC at a future date. Customers will benefit from streamlined privileged access in credentialed vulnerability scans. The CyberArk Secrets Manager, formerly known as “Conjur”, is a component in Privilege Cloud and Identity Security Platform Shared Services (ISPSS) deployments. The Tenable integration is compatible with both SaaS (cloud) and Enterprise (on-premises) deployments. Documentation for this Integration will be available on our documentation page under Integrations. Supported Authentication Types The CyberArk Secrets Manager integration can be used as an authentication method with the following credentials: SSH, including least privilege, privilege escalation, and SSH key authentication). SMB (Windows), including domain configuration. SNMPv3 Database integration, including the following database types: Oracle SQL Server MySQL MongoDB PostgreSQL DB2 Cassandra Sybase ASE VMware vCenter API VMware ESX SOAP API Nutanix Prism Central Impact There is no impact to existing scan configurations. Customers with CyberArk Secrets Manager are encouraged to use the integration for credentialed scans. Target Release Date January 20, 2026, TBD for SCCisco Meraki API Host Guidance
Summary Tenable is announcing changes to our documentation for the Cisco Meraki API integration. Customers using a “unique” host in the “Cisco Meraki Host” field of the credential should use “api.meraki.com”, or a region-specific instead if applicable. Please refer to the documentation for full guidance. Tenable and Cisco Meraki Integration Guide Impact Customers using the Cisco Meraki API integration are encouraged to check their configurations and update them accordingly. This change in guidance addresses cases where some customers were experiencing HTTP 308 redirects, resulting in integration failures. This is also closely related to cases where customers were experiencing HTTP 403 errors, which has been addressed by changes in the Cisco Meraki API Web Application Firewall (WAF). Release Date Dec 15th, 2025
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
Node.js Module Enumeration Detection Updates
Summary Tenable has updated the Node.js module enumeration plugins to reduce false positives and to better identify vulnerabilities when multiple packages are present on the scan target. Change Before this update, the Node.js module enumeration plugins did not attempt to associate detected packages with an RPM or DEB package managed by the Linux distribution. This would cause some packages to report vulnerabilities both based on a Linux distribution vendor’s advisory and a CVE advisory from the Node.js module maintainer. In addition, some Node.js installations on macOS that originated from third-party package managers, or from source, were not detected by the Node.js detection plugin. This would prevent the Node.js module enumeration plugin from running on those macOS assets. In some cases, a large volume of Node.js modules detected would cause the enumeration plugin to crash when attempting to report the list of modules in plugin output. After this update, these issues have been addressed. Vulnerable Node.js modules on Linux assets will be assessed to determine if they are managed by a Linux distribution’s package manager, and if so, will be marked as “Managed” and will not report a vulnerability, unless the Show potential false alarms setting is enabled for the scan. Node.js installs on Windows and macOS that were not previously detected due to the installation method will now be detected, and their installed modules will be enumerated. The module enumeration plugins will no longer report the list of detected modules in plugin output; rather, they will use only internal storage mechanisms to record the detected modules, so that Node.js vulnerability plugins can continue to use that data for version checks. Impact Most customers will notice a reduction in the volume of Node.js module vulnerabilities reported. Some Windows and macOS scan results may show an increase in detected vulnerabilities if Node.js was not previously detected based on the installation method. If a large number of modules is present on a scan target and had previously caused the plugin to malfunction and report no vulnerabilities, those targets may show previously unreported vulnerabilities, as the module enumeration plugin would now complete and allow the vulnerability plugins to execute.
