: Tenable typically only hosts the current ISO and images from the last four quarters on their public site. For specific older versions like a March 2022 build, you should contact Tenable Support directly. Why Avoid "Leaked" ISOs?
: For air-gapped systems, Tenable provides quarterly Offline Update ISOs . These should be applied in chronological order to ensure all security patches are correctly integrated.
: Official builds have SELinux enabled by default to provide mandatory access control.
To ensure your environment remains secure, always use the Tenable Downloads page for ISO files.
