Subject area for last log-in by user report

Summary

Is there a subject area where I can pull the last time a user logged in?

There's been a request by a department in my organization to see what employees have not logged into the system yet.  I'm thinking it would be easier to just pull the last login date.  I've looked through the Security subject area but did not see the relevant fields.  Is it possible to report on this data?  Thanks in advance for any assistance!
