Compliance scan results show you basic information about the scan. To determine whether hosts are compliant with user-defined policies, create specialized compliance reports (template based and interactive) based on compliance scan data.
Go to PC > Scans > PC Scans, hover over a scan and choose View from the Quick Actions menu. You'll see the scan results if the scan status is "Finished". If the scan is in progress, you'll see the latest information about your scan in the status window.
The Report Summary shows general information about the compliance scan and results, including the number of hosts alive at the time of the scan (Active Hosts), the number of hosts included in the scan target (Total Hosts), the scan reference number, the scanner appliances used, and the compliance profile (click the profile title to view the settings in the Appendix section).
The appendix provides additional information about the compliance scan, including a list of hosts that were scanned and not scanned, and the preferences set in the compliance profile applied to the scan task.
Sure, you can download scan results in multiple formats including XML.
