Partial score · DNS & email only

65/100

0–100, higher is better. How it is calculated

The website's security posture reveals several critical vulnerabilities that pose significant risks to business operations and reputation. Key issues include DNS resolution failures, lack of email authentication, and domain registration problems, which can lead to service outages, phishing attacks, and loss of domain control. Additional medium-level concerns such as missing security headers, GDPR compliance gaps, and absence of DNSSEC further increase exposure to data breaches and regulatory penalties. While SSL/TLS configuration is strong, foundational infrastructure weaknesses undermine overall security. Immediate remediation is essential to ensure availability, protect customer data, and maintain trust. Addressing these issues will strengthen compliance, reduce attack surfaces, and safeguard business continuity. The current state suggests urgent attention to DNS and email security as top priorities, followed by compliance and network hardening.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

4 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

    • Critical

      Domain Registration Issue

      Domain appears to be unregistered or expired

      What to do: Check domain registration status and renew if necessary

    • High

      No Name Servers Found

      Unable to find name servers for domain

      What to do: Configure proper name servers for the domain

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Technical notes

Notes

Critical findings include DNS resolution failures and absence of name servers, which can cause complete service outages and expose the domain to takeover risks. The missing domain registration data indicates potential lapses in domain ownership management. Email security is severely impacted by the lack of DKIM records and no email authentication configured, increasing susceptibility to email-based attacks and brand abuse. Medium-level issues such as failure in security headers and lack of DNSSEC implementation leave the site vulnerable to exploitation through common web vulnerabilities and DNS attacks. The GDPR and NIS2 compliance failures highlight gaps in regulatory adherence, potentially resulting in legal consequences. Despite a perfect SSL/TLS score, these infrastructural and policy weaknesses critically undermine the overall security posture.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
