User Authentication Bandwith

[Sagar_Jain19683]

We have proposed M365 Apps for enterprise for one of the BFSI Customer. They currently use Proxy server for Connecting across internet. 
They have doubts if their Current setup would be able to match the authentication bandwidth requirement for M365 Apps. 

Do we have any idea on how much bandwidth is consumed when the user is authenticated in M365 Apps??
