Multiple portal one agent view

Hello everyone, 
I am still new to Zendesk community, I am trying to study the possibility to implement  the solution for our costumers in the future , what i need to ask you is :  is it possible to set up multiple web portals with different branding  for our customers but centralize all the request and tickets in one agent view .

Please share with me your ideas and resources if it is possible .
Thank you in advance
