Hello tomqlopez, and welcome to the Greenbone community!
The Greenbone Enterprise TRIAL does not support scheduled scans. The reason for this is that it is only a short-term demo and not a full-fledged vulnerability management solution.
The rest of our enterprise appliance lineup fully supports schedules. If you are interested in further testing and purchasing an appliance, please contact our sales team.
I see. The test key only provides access to our Enterprise Feed as well some limited support. All other features depend on the type of the installed appliance.
Yes, the Community Edition includes the schedules feature.
However, note that some other features documented in our manual will still be missing, for example the whole Greenbone Operating System is not included.
In addition, we do not provide official support for the Community Edition, though you may get help from other users via our community!
