SEP Unmanaged clients should have a cloud connect feature to connect management server over the internet so we can push new polices to Unmanaged clients through the internet itself, No need the unamanaged client to come to our office network to update the new policies.
Seqrite Endpoint Console (Quickheal) has this feature named as Roaming clients in which the management server syncs with their cloud and roaming clients gets updated to new polices which we set on Seqrite Endpoint server
This is the most important feature missing in symantec.
