These are subscription level settings.
Storage - View the storage settings for scan results, as defined for your account, and change if you want. You can save results up to a maximum of 13 months.
Excluded Hosts - Hosts added to the excluded hosts list will never be scanned by the service, even if included in the scan target by a user.
Dissolvable Agent - You must accept the Dissolvable Agent (Agent) in order to perform certain types of security scans. Once accepted, the Agent is installed as needed on your Windows devices to collect host data. The Agent removes itself completely when the scan is complete.
Scheduled Scans - The Manager primary contact has the option to prevent the service from starting a new scheduled scan when there's an instance of it running. Also the Manager primary contact has the option to allow users to configure a scheduled scan to relaunch once a scan instance finishes. This supports continuous scanning.
Agentless Tracking - The Manager primary contact has the option to accept Agentless Tracking in order to track hosts by host ID. Once accepted, users can select agentless tracking on a per scan basis by selecting this option in Windows and/or Unix authentication records.
Scanner Trusted CA - The Manager primary contact has the option to accept this feature allowing Managers to create a list of private certificate authorities for use by the scanner.
