      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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.

Business context

Business profile

The business operates in the transportation sector, specifically automotive retail and services. It leverages its official Nissan partnership to maintain competitive advantage and brand trust. The company targets customers in the Worms region, offering both new and used vehicles, including electric and hybrid models. Revenue streams likely include vehicle sales, service and repair, and trade-in transactions. The presence of online service booking and trade-in valuation tools indicates digital maturity and customer convenience focus. The company maintains compliance with data protection regulations, enhancing customer trust. No parent or subsidiary companies are identified, suggesting an independent medium-sized enterprise. The partnership ecosystem includes Nissan and related service platforms. Strategic observations highlight a focus on digital engagement and localized market presence.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and cookie consent mechanisms are in place, indicating attention to privacy and security standards. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts like Usercentrics CMP is managed with asynchronous loading, reducing performance impact. Security headers are assumed but not explicitly confirmed, recommending further header hardening. Overall, the security posture supports business operations but would benefit from formalized policies and incident response documentation to enhance resilience and customer confidence.

Recommendations

  1. Implement and publish a dedicated security policy and incident response plan on the website.
  2. Add and verify security headers such as X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy.
  3. Introduce a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Conduct regular audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance website accessibility compliance to improve inclusivity and meet regulatory standards.

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.
