I’ve downloaded and installed the product and applied a trial license key. I don’t see anything that specifies any limits for the trial (for example: what can be done/not done, or how long it lasts).
For example, my policies are empty (and I haven’t found a place yet to download them, assuming you download the ones you’d want).
Also, I’ve tried to scan a local Ubuntu Linux 21 VM several times and the scan doesn’t seem to figure out the hostname or OS (although I have creds and sudo configured).
So far it’s just been able to “find” an ICMP vunlerability on that test host.
