What’s inside

14 checks, 4 areas, one score

Each check tells you the risk and where to verify it. Tick what you cannot confidently rule out, add up your score, and read what to do next.

Domain & spoofing

SPF, DKIM, DMARC enforcement and look-alike-domain monitoring — can someone send mail as you?

Inbound defences

External-sender banners, impersonation beyond Defender, a report button, company-wide remediation.

People & process

Out-of-band payment verification, exec-request rules, targeted BEC awareness for finance.

Visibility & compliance

Seeing what Microsoft missed, audit logs and retention, EU-hosted / GDPR evidence.
