Nessus Agent 10.3.0 Release Notes - 2022-11-17

Note: There is a known issue where upgrading and downgrading a Windows agent within a short period of time could cause the agent to become unresponsive. Tenable recommends that you do not upgrade or downgrade an individual Windows agent more than once every two hours. Doing so can cause nessus-service to stop. If this happens, restart the agent to restore nessus-service.

Changed Functionality and Performance Enhancements

The following are changed functionality and performance enhancements included in Tenable Nessus Agent 10.3.0:

  • Added support for the following operating systems:

    • macOS 13

    • Rocky Linux 8 and 9

    • AlmaLinux 8 and 9

  • Tenable Nessus Agent now supports FIPS mode communications.

Upgrade Notes

  • If you are connecting to Tenable Vulnerability Management through Tenable Nessus scanners, Tenable Nessus Agents, Tenable Web App Scanning scanners, or Tenable Nessus Network Monitors (NNM) located in mainland China, you must connect through sensor.cloud.tenablecloud.cn instead of sensor.cloud.tenable.com.

  • New Tenable Vulnerability Management Domain - As a part of continuous security and scalability improvements to Tenable infrastructure, we have added a new sensor.cloud.tenable.com domain that Tenable Vulnerability Management-linked Tenable Nessus Agents communicate with.

    • Tenable Vulnerability Management-linked Tenable Nessus Agents communicate with Tenable Vulnerability Management using sensor.cloud.tenable.com. If agents versions 8.1.0 through 10.3.1 are not able to connect to the new domain, they fall back to using cloud.tenable.com. Tenable Nessus Agent 10.3.2 and later do not fall back using the cloud.tenable.com domain.

    • Recommended Action: If you use domain allow lists for firewalls, Tenable recommends adding *.cloud.tenable.com (with the wildcard character) to the allow list. This ensures communication with sensor.cloud.tenable.com and all future subdomains, reducing operational overhead. Contact your network administrator for assistance with making necessary changes to your allow list.
  • You can upgrade to the latest version of Tenable Nessus Agent from any previously supported version.
  • If your upgrade path skips versions of the Tenable Nessus Agent, Tenable recommends reviewing the release notes for all skipped versions to learn about new features and bug fixes.
