Nessus 8.10.0 Release Notes - 2020-03-24

New Features

The following are the new features included in Nessus 8.10.0:

  • Backup and Restore Tool - Ability to create Nessus backups that can easily and quickly be restored.

    For more information, see Back Up Nessus and Restore Nessus in the Nessus User Guide.

  • Nessus Upgrade Plan - In Nessus Professional and managed scanners linked to Tenable.io, users can set a Nessus Update Plan that determines the version that Nessus updates to.

    The options are as follows:

    • Update to the latest GA release: Update to the latest version as soon as it is made generally available (GA).
    • Opt in to Early Access releases: Update to the latest version as soon as it is released for Early Access (EA), typically a few weeks before general availability.
    • Delay updates, staying on an older release: Remain on an earlier version of Nessus set by Tenable, which is at least one release older than the current generally available version. When Nessus releases a new version, your instance updates software versions, but stays on a version prior to the latest release. Note: Nessus never updates to a version earlier than 8.10.0, so this setting will impact upgrade to releases after 8.10.0.

    For more information, see Update Nessus Software in the Nessus User Guide.

  • Downgrade Option - Support downgrade to a prior version of Nessus.

    Note: Users cannot downgrade to versions prior to 8.10.0.

    For more information, see Downgrade Nessus Software in the Nessus User Guide.

  • Slow Rollout - Roll out new Nessus releases to the Tenable Update Server for licensed Nessus Professional and Nessus Manager installations separately from Tenable.io. New Nessus versions will be made GA for Tenable.io-linked scanners to auto-update one week after the GA for the release. The new version will be available on the Tenable Nessus Download page on the GA date, for customers that want to update earlier.

  • Predefine Nessus Manager linking key - In Nessus Manager, you can manually set the linking key for Agents and Nessus scanners to help streamline deployments.

    For more information, see Retrieve the Linking Key in the Nessus User Guide.

  • Specify scanner groups when linking scanners to Tenable.io - When linking Nessus scanners to Tenable.io using the CLI, you can set the scanner group to which to automatically add the scanner.

    For more information, see Nessus CLI in the Nessus User Guide.
