01 Mail authentication
SPF, DKIM, DMARC, MTA-STS and TLS-RPT — presence, syntax, enforcement, key strength — plus whether the mail exchangers offer STARTTLS and any dangling MX records. Whether your domain can be spoofed, and whether mail to it can be downgraded to plaintext.
02 DNS hygiene
Registrar lock, delegation consistency, nameserver behaviour, CAA records and DNSSEC as a full chain: signed, anchored at the registrar, DS-to-key match, signature expiry and algorithm strength.
03 Certificates and web headers
For every public hostname: expired or expiring certificates, certificates that do not chain to a trusted root, name mismatches, weak keys and deprecated TLS. Whether plain HTTP redirects and HSTS is actually sent.
04 Zone records and the CDN edge
With a Cloudflare token: subdomains pointing at retired hosting anyone could re-create, dangling CNAMEs, private addresses in the public zone, the CDN's TLS mode to the origin, and origins reachable around the proxy.
05 Both sides of mail authentication
Connect Exchange Online and the module reads what your own mail platform does with mail — accepted domains and DKIM signing, mail flow rules and connectors and whether they require TLS, remote domains, authentication policies, and the anti-spam, anti-phishing, anti-malware, Safe Links and Safe Attachments policies — beside what your domains publish, on the same row.
06 Which recipients a policy actually reaches
A policy can be switched on, correctly configured, pass its audit, and sit in the mail path of nobody. The module says which recipients each protection policy reaches — and names domains the tenant sends as that nothing is watching.
