Is´t possible to view when an asset was first and last discoverd.
When an asset report is created, information regarding vulnerabiliteis fist and last seen is availible, but I can´t se when the asset was first seen.
This information doesn't exist anywhere that's easy to get to. I'm sure a complex sql query could be written, but I'm guessing you're more interested in having it show up in a report or in the Asset Details?
Can you submit a Product Enhancement Request and clarify where you think it should appear. You can get to the PER page here:
