Email spoofing protection for small business: can anyone send email as you?

Without the right records in place, anyone can send a message that appears to come from your company's domain. It is how many fake-invoice and "change of bank details" requests reach your clients and suppliers, looking like they came from you.

The good news: whether your domain is protected can be read from public DNS in a few minutes. Nothing to install, no access to your systems.

What the scan looks at

SPF: which servers are allowed to send email for your domain.
DKIM: whether your messages carry a signature that proves they were not altered.
DMARC: the policy that tells receiving mail servers what to do with messages that fail the first two checks.

You get a plain-language result and an honest next step. For most small businesses, the fixes are routine work your IT provider can do in about an hour.

Why it matters now

Cyber insurance renewal questionnaires increasingly ask about email authentication, alongside multi-factor authentication and backups. Knowing your answer before the form arrives makes the conversation with your broker simpler.
