5 of 36 Windows computers past end of support. For example LAPTOP-HUGHES (robert.hughes@northwindtraders.example): Windows 10 stopped getting security updates on 14 Oct 2025. Extended Security Updates or LTSC can cover it; otherwise upgrade.
Fix: Upgrade computers on Windows 10 or an old Windows 11 release to the current Windows 11 release. See the rows →
-
4 accounts inactive for 90+ days or never used. For example hannah.robinson@northwindtraders.example: Licensed member, last signed in 7 Apr 2026.
Fix: Disable accounts that haven't signed in for 90 days, or were created over 30 days ago and never used. See the rows →
-
1 of 2 admin accounts also has a licence or mailbox, so it looks like an everyday account: ann.patel@northwindtraders.example.
Fix: Give each administrator a separate, unlicensed admin account with no mailbox, used only for administration, and take the admin roles off the account they use every day. See the rows →
-
1 disabled account still licensed. For example robert.hughes@northwindtraders.example: Disabled, holding 1 licence.
Fix: Remove licences from disabled accounts, or convert leavers' mailboxes to shared mailboxes. See the rows →
-
1 guest with admin roles. For example g#EXT#@northwindtraders.example: Guest holding Exchange Administrator.
Fix: Remove admin roles from guest accounts. See the rows →
Firewalls
Your evidenceEvery device and network in scope sits behind a firewall that blocks unauthenticated inbound connections by default, with changed passwords, reviewed rules and no administration from the internet.
A boundary firewall (or the router's firewall) protects each internet connection, and home workers are protected by the firewall on their device.
A [make and model] firewall protects the internet connection at [site]. Home and remote workers are protected by the software firewall on their company devices.
What Microsoft 365 can't show: Firewalls aren't part of Microsoft 365. Intune can enforce the Windows firewall, but reading its configuration profiles needs a permission the app doesn't hold, so answer from the firewall itself.

Secure configuration
FailDevices and cloud services run only the software, services and accounts they need, with default passwords changed, automatic running of files off and devices that lock.
Software and services nobody uses are removed or turned off on every device.
New devices are set up from [a standard build or Windows Autopilot] without unnecessary software, and unused software and services are removed [during regular reviews by the IT provider].
What Microsoft 365 can't show: Microsoft 365 doesn't report what's installed on devices.

Services that aren't needed are turned off in cloud services too: for Microsoft 365, the legacy sign-in protocols that can't use MFA, and SMTP AUTH on mailboxes that don't send mail that way.
- Legacy authentication is allowed.
- No enabled policy blocks legacy authentication for all users
- SMTP AUTH is on for the organisation.
- SMTP AUTH is allowed
Fix: Block legacy authentication (Exchange ActiveSync and other clients) with a Conditional Access policy for all users. Legacy protocols can't do MFA and are the most common password-spray target. See the rows →
Legacy authentication is allowed. SMTP AUTH is on for the organisation.
What Microsoft 365 can't show: Judged from Conditional Access and Exchange Online settings.

Passwords are protected from brute-force guessing (A7.10: MFA, throttling or lockout) and their quality is managed technically (A7.11: MFA, 12 characters, or 8 characters with a deny list).
- Microsoft Entra ID requires passwords of at least 8 characters, blocks commonly used and known compromised passwords (Microsoft's global banned password list) and locks out repeated failed sign-in attempts (smart lockout). These are Microsoft defaults for cloud accounts. Multi-factor authentication is enforced as well (see the MFA answer), so a guessed password alone can't be used to sign in.
