Short answer
FirstNet hardens Microsoft 365 sign-in with multi-factor authentication (MFA), conditional access and privileged identity management as part of its Microsoft 365 security and compliance service. For a finance-sector client, conditional access and MFA adoption reduced account takeovers.
In detail
Weak identity controls are a root cause of many breaches. In general terms, each control does a different job:
- MFA asks for a second proof of identity, so a stolen password alone is not enough to sign in
- Conditional access checks conditions such as the user, device, location or sign-in risk before granting access
- Privileged identity management limits standing administrator rights, reducing what a compromised admin account can do
How the rollout is handled matters as much as the policies. FirstNet sets policy baselines, rolls changes out in stages under change control and communicates each phase clearly, prioritising controls that add protection with minimal friction for users. Dashboards then track incidents, drift and user risk signals, and admin and end-user training helps the changes stick.
Conditional access and privileged identity management depend on your Microsoft Entra ID licence level. FirstNet is a Microsoft Cloud Solution Provider and can supply Entra security add-ons if your current licences fall short.
