The standard stack
People verified first, controls in front, business systems behind them.
Every user proves MFA, then passes conditional access, before anything else happens — hourly staff from trusted IPs on site, salaried staff on site or remote from an Intune-compliant device. Identity, endpoint and email controls sit in front of the network core, so nothing reaches cloud productivity or ERP without passing through them. The specifics of any one deployment stay in that customer's documentation, not on this page.
