Conclusion
Downloading Nessus update plugins is essential to maintaining the effectiveness of your vulnerability scanner. By following the steps outlined in this article, you can easily download and install the all-20.tar.gz file, ensuring your scanner has the latest plugins to detect emerging threats.
To update Tenable Nessus plugins manually—typically for air-gapped or offline systems—you use the all-2.0.tar.gz archive. This file contains the complete set of scripts used by the scanner to identify vulnerabilities. Downloading the Plugin Archive
Because these archives are tied to your specific license, they are not available through a general public download link. To obtain the correct all-2.0.tar.gz file:
Generate a Challenge Code: On your offline Nessus machine, run the following command to get a unique identifier: Linux: /opt/nessus/sbin/nessuscli fetch --challenge
Windows: "C:\Program Files\Tenable\Nessus\nessuscli.exe" fetch --challenge
Visit the Offline Registration Page: Use a machine with internet access to go to the Tenable Offline Registration Page.
Submit Details: Enter your Challenge Code and your Activation Code (found in your Tenable Support Portal account).
Download: After submitting, you will receive a custom URL to download the all-2.0.tar.gz archive and a nessus.license file. Installing the Plugins
Once you have moved the all-2.0.tar.gz file to your offline system, you can install it using the Command Line Interface (CLI) or the User Interface (UI). Via Command Line (Recommended) while [[ $# -gt 0 ]]; do case
Open a terminal or command prompt as an administrator and use the update command: Linux: # /opt/nessus/sbin/nessuscli update all-2.0.tar.gz
Windows: "C:\Program Files\Tenable\Nessus\nessuscli.exe" update all-2.0.tar.gz
macOS: # /Library/Nessus/run/sbin/nessuscli update all-2.0.tar.gz Via User Interface Log in to the Nessus UI (usually https://localhost:8834). Navigate to Settings > Software Update. Click Manual Software Update.
Select Upload your own plugin archive, choose your all-2.0.tar.gz file, and click Continue. Key Considerations
Permissions: You must have System Administrator privileges to perform manual updates.
Consistency: Offline systems should be updated regularly (e.g., daily or weekly) to ensure the scanner can detect the latest threats, as it cannot receive automatic updates.
Tenable Security Center: If you are using Tenable Security Center, the process is slightly different; you upload the plugin archive through the System > Configuration > Plugins/Feed menu. Perform an Offline Nessus Plugin Update
No. Nessus 7.x requires the “all-2.0” tarball (different schema). Using “all20” will corrupt your plugin database. Always match the major Nessus version.
