Is Microsoft 365 Business Premium enough for cyber insurance?

It provides the tools — not the configuration. Insurers want evidence of enforcement: MFA, patching, backups tested, and admin controls. Unconfigured Premium fails practical assessments.

Who should own M365 security — MSP or consultant?

MSP owns BAU tickets and monitoring after baseline. A consultant or sprint partner owns initial CA design, evidence pack, and cutover — work that needs senior identity engineering, not queue time.

How often to retest backups?

Quarterly restore tests for critical workloads are a common insurer expectation. Document who ran the test, what was restored, and how long it took.

Microsoft 365 security baseline for SEQ businesses before cyber insurance renewal

Insurers and customers now ask for proof beyond “we have Microsoft 365 Business Premium.” This baseline covers Conditional Access, legacy auth, backup evidence, and admin hygiene — the items Brisbane assessors actually check.

Microsoft 365 security in Brisbane is the default stack for SEQ SMBs — but Business Premium with defaults is not a baseline. Insurers ask for MFA coverage, admin separation, logging retention, and backup restore proof.

Providers range from MSP bundled security to specialist assessments. The winning pattern: close ML1-aligned gaps fast, document evidence, then let your MSP run BAU monitoring.

Non-negotiable controls

Conditional Access: block legacy authentication, require MFA for admins and all cloud apps.

Privileged Identity Management or equivalent break-glass process — no daily global admin on laptops.

Unified audit logging enabled with retention that matches insurer wording.

Defender for Office 365 policies aligned to real attachment types you receive.

Backup: Microsoft native + verified third-party or immutable copy — with restore test date.

Common Brisbane failure modes

Shared mailbox treated as personal login — MFA gaps.

Contractors with permanent admin “because they set it up in 2019.”

Intune enrolled for some devices, not field laptops.

“We backup OneDrive” with no SharePoint or Teams scope documented.

90-day baseline sequence

Day 1–14: identity inventory, legacy auth off, CA policies in report-only then enforce.

Day 15–45: admin roles, LAPS, patch rings, macro policies.

Day 46–90: backup restore test, insurer one-pager, handover runbook to MSP.

North Ark FC-05 packages this as fixed scope alongside your existing M365 partner.
