Conditional Access is a Microsoft Entra ID policy engine that grants or blocks access to apps based on conditions you define.

Leaders should care because the issue shows up as cost, risk, or lost capacity, not as a technical curiosity.

1.Inventory critical apps
Email, VPN, admin portals, finance systems.
2.Require MFA for users and admins
Phased rollout with break-glass accounts managed carefully.
3.Tighten device and location rules
After baselines are stable.
