Minimum number of SEP clients supported by GUP

Hi,

We have 1300+ offices in our organization spread acorss the globe and have SEP client configured to protect workstations in these offices. Some offices have below 100 computers and some offices have 200 computers. Do we need the GUP server for offices where SEP client count is 100.

Presently, Our enviorment have SEP 14 version configured on GUP and SEP Clients.

Any suggestions are welcome.

Thanks

KK
