A CLEARER PICTURE, FAST

Review the controls that matter
Inspect SPF, DKIM, and DMARC side by side, with plain-language findings on policy strength, lookup limits, and tested selectors.
Put DNS in context
Identify recognised authoritative DNS providers and public registration data. Optionally inspect the network owner behind the domain’s web address.
