Thanks for your response. But, i am looking at can Q2 configure at only at domain level instead of including the sub-domain name. let me explain a bit more details what i was referring to the main domain name. Say domain name abc.com has 3 sites a.abc.com, b.abc.com, c.abc.com then in this we should include all FQN or just .abc.com. In addition to this, the whitelisting done at Network layer 7 or 5.
