This file is the "gold standard" for security professionals managing air-gapped or restricted networks where automatic updates are not possible.
Reliability: The offline update method is highly stable and acts as the primary fallback for failed internet-based updates.
Convenience: Users can perform the update through the Nessus User Interface by selecting "Manual Software Update" or via the command line for automated scripts.
Speed: While the initial plugin update can take a significant amount of time (often referred to as "taking forever" by users), subsequent incremental updates are typically much faster.

The keyword "download nessusupdateplugins all20targz" refers to the manual update process for Tenable Nessus plugins using a compressed archive file, typically named all-2.0.tar.gz. This process is critical for "air-gapped" or offline environments where the scanner cannot reach Tenable’s update servers directly. Understanding the "all-2.0.tar.gz" File
Nessus plugins are essentially programs written in the Nessus Attack Scripting Language (NASL) that contain vulnerability information and remediation steps. The all-2.0.tar.gz archive is the standard format for a full set of these plugins.
Purpose: It allows for a manual, offline update of the scanner’s vulnerability database.
Source: For security reasons, you should only obtain this file from the official Tenable site or through your Tenable Support Portal account. How to Download the Official Plugin Archive
To download the correct file for an offline instance, you must first generate a unique download URL:
Generate Challenge Code: On the offline Nessus machine, run the following command in your terminal or command prompt: Linux: /opt/nessus/sbin/nessuscli fetch --challenge
Windows: C:\Program Files\Tenable\Nessus\nessuscli.exe fetch --challenge
Access the Offline Portal: On a computer with internet access, visit the Tenable Offline Registration page.
Enter Credentials: Input your Challenge Code and your Nessus Activation Code.
Download: Click submit to receive a unique URL. This URL will prompt you to download the latest plugin archive, such as all-2.0.tar.gz. Installing the Plugins download nessusupdateplugins all20targz top
Once you have transferred the file to your offline Nessus scanner, you can install it using the UI or the CLI. Option 1: Using the User Interface (UI) Log in to Nessus as an administrator. Navigate to Settings > Software Update. Click Manual Software Update in the top right.
Select Upload your own plugin archive and choose the all-2.0.tar.gz file you downloaded. Install Plugins Manually (Tenable Nessus 10.12)
Manually updating Nessus plugins using the all-2.0.tar.gz file is a common task for security administrators managing "air-gapped" scanners or installations with restricted internet access.
The process typically involves obtaining a challenge code, downloading the archive from the Tenable Support Portal, and using the nessuscli tool to perform the offline update. How to Manually Update Nessus Plugins
Updating a Nessus scanner offline requires moving the plugin archive to the host machine and executing a command-line update.
Generate a Challenge Code: On your Nessus host, run the command nessuscli fetch --challenge to generate a unique identifier for your installation.
Download the Archive: Visit the Tenable Offline Registration page. Enter your challenge code and activation code to receive a link for the all-2.0.tar.gz file.
Transfer the File: Move the downloaded .tar.gz archive to the scanner’s directory (e.g., /opt/nessus/sbin/ on Linux or the installation folder on Windows). Install the Plugins: Run the update command: Linux: /opt/nessus/sbin/nessuscli update all-2.0.tar.gz Windows: nessuscli.exe update all-2.0.tar.gz
Restart the Service: Restart the Nessus service (service nessusd restart or via Windows Services) to allow the scanner to re-index the new plugins. Common Troubleshooting Tips
Permissions: Ensure the user executing the nessuscli command has administrative or root privileges to write to the plugin directory.
GUI Syncing: Users on the Cisco Community have noted that if plugins don't appear in the web interface after an update, manually importing a single plugin via the GUI can sometimes trigger a full refresh.
Disk Space: Plugin archives are large and require significant space during the extraction process; ensure the /opt/nessus or installation partition has at least 5-10GB of free space.
For official documentation and the latest command syntax, refer to the Tenable Nessus User Guide.
