New Windows DACL Compliance Check Types Now Available
Summary Tenable is pleased to announce the release of three new atomic compliance check types for Windows auditing: FILE_DACL, REGISTRY_DACL, and SERVICE_DACL. These check types give audit authors a cleaner, more expressive way to assess discretionary access control list (DACL) permissions on files, registry keys, and services. Change These check types improve upon FILE_ACL, REGISTRY_ACL, and SERVICE_ACL check types. The rename to DACL reflects the correct Windows security terminology and aligns with how permission auditing is actually described in benchmarks and hardening guidance. The Audits & Compliance team will be using these check types for all published audits going forward and will be updating existing content to use them. Impact Easier check writing - Each permission check is a single, self-contained atomic check. There is no need to pair a check with a companion ACL structure. The access control criteria are expressed directly in the check itself, reducing the surface area for authoring errors. Easier tailoring - Because all relevant information lives within the atomic check block, policy customization is straightforward. Reviewers, implementers, and content consumers can read exactly what a check requires without cross-referencing a separate structure in the .audit file. Documentation - Usage and examples are available in the Nessus Compliance Checks Reference: FILE_DACL https://docs.tenable.com/nessus/compliance-checks-reference/Content/FILE_DACL.htm REGISTRY_DACL https://docs.tenable.com/nessus/compliance-checks-reference/Content/REGISTRY_DACL.htm SERVICE_DACL https://docs.tenable.com/nessus/compliance-checks-reference/Content/SERVICE_DACL.htm Target Release Date August 27, 2026

Read the Tenable One AI Exposure press release Tenable One Cloud Exposure Identify non-compliant post-quantum cryptography cloud resources Encrypted traffic captured today can be stored and decrypted later, once quantum computing matures, a threat known as harvest-now-decrypt-later (HNDL). Organizations relying on outdated Transport Layer Security (TLS) configurations or non-quantum-safe encryption are exposed to this risk without even knowing it. Tenable One Cloud Exposure now helps customers identify non-compliant post-quantum cryptography (PQC) cloud resources to support future compliance regulations. We’ve added four new properties to the Network Endpoint profile for HTTPS-supported endpoints. The enhancement allows teams to: Get visibility into quantum readiness: See which endpoints already support post-quantum cryptography and which don’t, so you can prioritize upgrades ahead of emerging compliance mandates. Get all non-PQC-compliant resources listed in one query. Identify weak encryption faster: Surface outdated TLS versions and vulnerable cipher suites across your environment without manual audits or separate scanning tools. Reduce HNDL exposure: Proactively harden key exchange methods and ciphers before intercepted traffic becomes a future liability. Gain compliance evidence: Customers in regulated industries, such as healthcare and financial services, can easily prove compliance as quantum computing matures. To find these resources in your cloud environment, go to Tenable One Cloud Exposure and filter or query “non-ready PQC resources” using the Network Endpoint page or Explorer. Check out other recent releases in the product documentation Tenable One OT Exposure Deeper IT/OT visibility for every corner of your environment Our latest release of Tenable One OT Exposure 4.7 expands visibility for grid operators and disconnected environments, and introduces a variety of productivity enhancements.

Summary This update introduces a significant infrastructure enhancement for NASL plugins, enabling support for the HTTP/3 protocol. While the underlying framework now supports HTTP/3, there are currently no plugins that leverage the HTTP/3 protocol. Individual plugins will be updated by Tenable as appropriate to utilize this capability over time. Change The core of this update will allow NASL plugins to dynamically negotiate and utilize either HTTP/1 or HTTP/3 for requests. We are releasing http3_detect.nasl (Plugin ID: Pending) as the initial plugin to leverage this new framework, providing the foundation for future protocol-aware detections over UDP. To utilize HTTP/3, customers must explicitly enable 'UDP port scanning', 'Search for SSL/TLS/DTLS services' and set an appropriate port range in ‘Search for DTLS on’ within their scan policy settings. Care should be taken as UDP port scanning can significantly slow down scans. Customer Impact Existing plugins remain unaffected and will continue to operate over HTTP/1 unless specifically updated by the Tenable Research team. The introduction of http3_detect.nasl serves as the first step in broader protocol support without impacting current scan performance for non-UDP focused scans.

Tenable One - Platform updates Integrate application security data into Tenable One for code-to-runtime security Your codebase is growing faster than your security program, and in the age of AI, developers are introducing security findings at 10 times the rate of their peers. It is critical to see code as part of your entire attack surface. Application security data now integrates directly into Tenable One to further close visibility gaps and ensure secure code development in the AI era. Whether code is human- or machine-written, you can now integrate application security risks, like those from Snyk, Claude Security, or any other application security tool via Tenable One Connectors — directly alongside your existing exposure data. What this means for you: Achieve full code-to-runtime visibility by bringing application security risks together with the rest of your exposure data in one place. Fix code flaws before they become incidents by identifying your most business-critical code flaws and fixing them early in the development lifecycle. Measure organizational exposure and transform technical static code vulnerabilities into clear risk metrics on business resilience. Read the blog post Explore the guided demo Check out Open Connector documentation and Snyk Connector documentation Improved workflow orchestration capabilities in Tenable One Vulnerability Management and Tenable One New enhancements to Tenable's workflow orchestration capabilities are now generally available. This release streamlines remediation workflows and improves operational efficiency with the following key updates: Plugin output in tickets: You can now attach Plugin Output directly to tickets, providing immediate context and critical information while eliminating the need for further navigation. Tenable Hexa AI for ServiceNow: You can now leverage Tenable Hexa AI for ServiceNow incident and initiative creation to match already available Jira functionality. Review the exposure management release notes Review the Tenable Vulnerability Management release notes Tenable unified scoring is now live Tenable has unified its risk prioritization standard, moving the high-fidelity Vulnerability Priority Rating (VPR) model out of beta to become the sole standard. To sharpen your prioritization, an updated asset classification engine also delivers more accurate Asset Criticality Ratings (ACR) for your assets. Because VPR and ACR feed directly into your Cyber Exposure Score (CES) and Asset Exposure Score (AES), your console will automatically update to reflect a precise understanding of your exposure. These recalculations occur automatically, though completion times depend on the size of your environment. To prevent errors in your saved views, you must manually update any filters or combinations that still use VPR v1. No data migration is required.

Improvement 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.

Tenable One Vulnerability Management Automate remediation with direct ticketing Stop bouncing between disconnected tools. You can now create Jira or ServiceNow tickets directly within your Explore Findings view and launch Exposure Response Initiatives straight from Vulnerability Intelligence. Even better, Tenable automatically closes these tickets the moment a vulnerability is fixed, eliminating tedious manual cleanup for your team. To keep your security and IT teams aligned, we've also added live ticket log tracking inside the finding details page, new ticket filters for your findings table, and easy exports for Exposure Response logs. To get started, check out our documentation or interactive tour. Clear your blind spots and validate your security coverage To protect your network, you need to know your security tools are working correctly. New dashboards and reports help you eliminate hidden gaps and prioritize fixes faster. The program health dashboard monitors your deployment health and scanning coverage. It gives you a central view to ensure your security agents are active and fully patched, preventing silent operational failures. The program health report unifies fragmented asset data and scan authentication indicators into a single document. It resolves conflicting inventories and credential issues, giving you a clean, trusted report to plan and execute remediation. The endpoint application visibility dashboard cuts out the hours your team spends hunting down software inventories. It automatically consolidates application data across endpoints so you can prioritize fixes based on real-world exploit likelihood and deployment scale.

NuGet Package Enumeration Updates
Summary Tenable has updated the NuGet package enumeration plugins to improve detection of installed NuGet packages on Linux/Unix scan targets. Change Before this update, the NuGet package enumeration plugins did not attempt to associate detected packages with an RPM or DEB package managed by the Linux distribution. This could cause packages to report vulnerabilities both based on a Linux distribution vendor's advisory and a CVE advisory from the NuGet package maintainer. After this update, these issues have been addressed. NuGet packages 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. Impact Most customers will notice improved accuracy in NuGet package vulnerability reporting. Scan results may show changes in detected vulnerabilities based on how packages were previously assessed. Affected plugins 190687 - NuGet Installed Packages (Linux / Unix) Target Release Date June 1, 2026
Cisco 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).
