Authentication with Azure AD if Azure is not allowed by the FW

Hello Community,

this is my first port and I hope I get support from you.
short question, is it possible to authenticate with Azure although Azure is blocked by the firewalls?
I read that Zscaler connects directly to O365 and so the MPLS is thus avoided.

Thank you.

Hello Community,

any help please?

Best regards

Authentication will happen only if the user able to reach your idp.
