Domain & network

Are your domain and email infrastructure properly protected? Your site is more than the pages a browser shows. Your domain, DNS and email setup also carry important security and reliability signals.

One page. One pillar. A real report.

Enter your website and we’ll email you a report on Domain & network for your home page. Please allow at least 24 hours.

Our plans cover the 9 pillars across the pages of your whole site.

What we check

  • The expiry date of your domain name, and the setting that forbids its transfer until someone lifts it at your registrar.
  • The name servers: how many there are, how diverse they are, and, where DNSSEC is used, whether the zone is signed to protect DNS response integrity.
  • The records that do, or do not, allow a third party to email your customers in your name (SPF, DKIM, DMARC). They are read down to the detail: a record that is present but incomplete protects nothing while looking in place, which is worse than a plain absence.
  • CAA records, when published, which restrict which certificate authorities are allowed to issue certificates for your domain.
  • Your exposed subdomains, some of which may still point to an abandoned service that a third party can claim.
  • Where your addresses resolve, at which operator, and on which network.

What we find on the sites we audit

Across about 20 to 30 websites we audited between August 14, 2026 and September 24, 2026:

  • 75% haven't signed their DNS zone (DNSSEC)
  • 10% receive email with no SPF or DMARC record protecting their name
  • 15% had a domain name less than 90 days from expiry

Each percentage covers the sites where the point could be checked. Many were audited because a defect showed up quickly, so these figures describe our audits, not websites in general.

On what basis

SPF (RFC 7208) · DKIM (RFC 6376) · DMARC (RFC 9989) · DNSSEC

A finding is only worth something if it rests on an identifiable basis. Where one exists, we rely on a law, a standard or a specification, and for every point recorded the report names the page and gives the value we measured.

What it changes for you

This is the quietest pillar. A domain that expires cuts off the site and the mail. A mail service without protection lets a third party write to your customers in your name.

These settings are not fixed in the site: they live at your registrar, and nobody looks at them as long as everything works.

What this audit does not say

We read what the public registries and the name system publish: you can check it yourself, with the same tools.

Whether your emails actually land in inboxes, and your sender reputation, depend on data only the domain owner can access. The report covers what is published, not what gets delivered.

Every limit of the examination is stated in the methodology note of your report. A point that cannot be verified is never presented as compliant.

The weight of this pillar

An overall score has to weigh what matters for your business: the 9 pillars do not carry the same weight depending on what your site is for. Here is what “domain & network” represents in the overall score, under each weighting. The report always states which one produced your score.

Guides for this pillar

DNSSEC: what it does and doesn't protect

DNSSEC signs your domain's DNS answers so they can't be forged. What it covers, what it doesn't encrypt, who turns it on, and what the audit checks.

DMARC: who can send email as your domain?

DMARC tells mailbox providers what to do with email that spoofs your domain. The three policies, the Gmail and Yahoo rules, and what the audit reads.

Domain expiration: what stops, and when

When a domain expires, your website and email stop the same day. Why renewals fail even on auto-renew, and what the audit reads from the registry.
