Upgrade Notes

  • New Domain - As a part of continuous security and scalability improvements to Tenable infrastructure, we have added a new domain that agents communicate with.

    • Starting with Agent 8.1.0, agents communicate with using In case agents are not able to connect to the new domain, they fall back to using Agents with earlier versions will continue to use the domain.

    • Recommended Action: If you use domain allow lists for firewalls, Tenable recommends adding * (with the wildcard character) to the allow list. This ensures communication with and all future subdomains, reducing operational overhead. Please contact your network administrator for assistance with making necessary changes to your allow list..
  • You can upgrade to the latest version of Nessus Agent from any previously supported version.
  • If your upgrade path skips versions of Nessus Agent, Tenable recommends reviewing the release notes for all skipped versions. You may need to update your configurations because of features and functionality added in skipped versions.
  • Agents now support the ability to choose your Agent update plan:

    • By default, the Agent update plan is set to update to the generally available (GA) version .

    • If you want to manually update your Agents to the newest version when it is made available for Early Access (EA), first disable automatic updates so the agent does not automatically downgrade to the previous version (GA).

    • If you want your Agent to automatically update to the newest version, set your Agent update plan to ea.

  • Nessus Agents 7.7.0 and later support the capability to downgrade from a later version:

    • Nessus Agents support automatically downgrading via the Agent update plan setting. To automatically revert a Nessus Agent to the previous version, set your Agent update plan to stable. Your agent will always remain on an earlier version than the latest GA version until you change your update plan.

    • To manually downgrade a Nessus Agent to a previous version (7.7.0 or greater), first disable automatic updates, then obtain the Agent package from Tenable Support and install it over your current version.
