Tenable.io Vulnerability Management has made further updates to the way scan results are displayed in the UI. Effective May 26, 2020, scan results that are older than 60 days will no longer be viewable in the Tenable.io UI. Older scan results will still be available for export until they expire at 15 months. There is no change to the way results are displayed for data younger than 60 days.  Customers can still view those results in Tenable.io, as well as export the results. This change is limited to results of individual scans results and does not impact workbenches, dashboards, reports and other features of Tenable.io.
