Find out if your domain can be used to impersonate your business.

Check the public DNS controls that help stop fake invoices, supplier impersonation, and phishing emails sent under your brand.

Why this matters

Email spoofing lets criminals send messages that appear to come from your business. If your SPF, DKIM, and DMARC settings are weak, attackers may be able to impersonate your domain when targeting customers, suppliers, and staff.

This check uses public DNS records and scoring logic to explain whether your domain appears materially spoofable. It is a fast triage check, not a full security audit.

Terms for this free check

By running this check, you confirm that you are authorised to request a public DNS review for the domain entered. The check uses publicly available DNS information only and does not access mailboxes, systems, accounts, or private data.

The result is general information, not a complete cybersecurity audit, legal advice, compliance certification, incident response service, or guarantee that a domain is secure. DNS records can change, third-party resolvers may return incomplete data, and some controls such as DKIM alignment cannot always be fully proven from common public selectors.

Addictive Technology Solutions provides this free check on an as-is basis and excludes liability to the maximum extent permitted by law for decisions, losses, incidents, missed issues, or business interruption arising from use of the check. You remain responsible for validating and implementing any security changes through qualified support.

If you request the full cyber hygiene health check, your submitted contact details and scan result may be stored as a sales lead and used by Addictive Technology Solutions to contact you about relevant cybersecurity or Microsoft 365 services.
