Partial score · DNS & email only

75/100

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

The website demonstrates a strong security foundation with no critical or high severity vulnerabilities identified, and perfect scores in email security, SSL/TLS configuration, and overall network security posture. However, there are medium-level concerns primarily related to compliance and DNS configurations that require attention. The failure in Security Headers implementation and missing DNSSEC support could expose the site to certain attack vectors such as man-in-the-middle or content injection attacks. Additionally, the GDPR and NIS2 compliance issues indicate potential gaps in regulatory adherence, which could result in legal and financial risks. While low-level issues like missing CAA records are less immediately impactful, addressing them will enhance domain security. Overall, the site is secure but improving header policies, DNS security, and compliance controls will reduce risk and support business trust and regulatory alignment.

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

No critical or high findings. These medium findings are worth fixing next.

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

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

The most critical findings include the failure in Security Headers and missing DNSSEC support. Security Headers are essential HTTP response headers that protect users from attacks like cross-site scripting (XSS), clickjacking, and protocol downgrade attacks; their absence or misconfiguration leaves the website vulnerable. DNSSEC not being enabled means the DNS responses for the domain are not cryptographically signed, allowing attackers to perform cache poisoning or spoofing attacks. GDPR and NIS2 failures highlight gaps in compliance frameworks which can lead to data privacy violations and regulatory sanctions. Although email security and SSL/TLS configurations are exemplary, the DNS Health score of 85/100 reflects the DNSSEC and CAA issues that should be remediated to strengthen domain security.
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.
