I have an issue with home VPN users who get on network for like 1hr and sign off.  Their laptops might be fully up-to-date, but still show as having vulnerabilities (because they didn't scan in the 1hr of being on network).  

How can I manually initiate a vulnerability scan?   by doing a Patch Scan on a system? are they the same? and it will show results immediately in Threats and Patches?    

Ist there a way to have a system that hasn't scanned in awhile to immediately scan when it connects?   something like; no scan in 7 days = immediate scan on next connect, don't wait for schedule.  I like that feature!

thanks!
