This report identifies vulnerabilities in your account with associated tickets.
For a Manager, this report includes all tickets in the subscription, including tickets with invalid IPs and users (tickets that appear grayed out on the tickets list). For a Scanner or Reader, this report includes tickets for hosts assigned to your account and that are assigned to you or another user in your business unit. This means that if a ticket is for a host that is assigned to your account but it is assigned to a user in another business unit, then the ticket is not included in your report.
This is the average number of days it took for tickets to be closed. When calculating the average we include 1) tickets that moved directly from Open to Closed state by the service, and 2) tickets that were previously marked Resolved (by a user) and are now marked Closed/Fixed.
