What Irish & UK SMEs usually find when we look at their M365 tenant

Forwarding rules no one set up

We routinely find mailboxes silently auto-forwarding every inbound email to an outside Gmail. Sometimes it's a former employee. Sometimes it's a compromise. Either way, it's been running for months. Our review enumerates every forwarding rule across the tenant.

MFA gaps in the wrong places

MFA is on for 'most' users. The exceptions are the directors, the finance team and the service accounts — the exact accounts attackers want. We map MFA coverage against role and flag the gaps in writing.

DMARC at 'p=none' for years

Your domain has SPF and DKIM, and DMARC is published — but at policy 'none', which is observational only. Spoofed mail still gets delivered. We chart the path from 'none' to 'quarantine' to 'reject' with the legitimate-sender inventory you need so nothing breaks.

Conditional Access policies that exist but don't apply

Conditional Access is on the menu. Someone built three policies a year ago. None of them are scoped properly, two are in report-only mode forever, and the compliant-device requirement was scoped out for an emergency that's been over for six months.

What we check in the free M365 review

Identity & access posture

MFA coverage across the tenant. Privileged role assignments. Stale guest accounts. Sign-in logs for anomalies. Password-spray and impossible-travel signals. Service accounts and legacy-auth exceptions.

Email security & impersonation

DMARC posture (enforcement, alignment, reporting). SPF + DKIM correctness across all sending domains. Inbound impersonation risk — display-name spoofing, lookalike-domain awareness. Outbound mailbox forwarding rules.

Conditional Access & Zero-Trust posture

Every active CA policy listed, scope assessed, gaps flagged. Block-legacy-auth, require-compliant-device, MFA-from-untrusted-network, risk-based sign-in — your current state vs. NCSC / Microsoft baseline.

Data protection & DLP

SharePoint / OneDrive sharing posture. External-sharing defaults. Anonymous-link exposure. DLP policies and how they fire. Sensitivity labels — whether they exist and whether anyone uses them.

Secure Score & Microsoft baseline

Tenant Secure Score with the highest-impact uplift items prioritised. We don't chase the score for its own sake — we pick the controls that genuinely reduce risk for your shape of business. Mapped to NIS2 / GDPR Art. 32 evidence requirements.

Optional paid engagement — hardening & ongoing oversight

Where the free review surfaces work, we can do the hardening directly: DMARC migration to p=reject, Conditional Access rebuild, privileged-access overhaul, Intune rollout, sensitivity-label deployment, training. Monthly oversight retainer available.
