This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

Priority findings

1 finding rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

  • 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

Mercteil operates in the automotive retail sector, focusing on genuine tuning and spare parts for premium car brands. Its business model is e-commerce with a global customer base. The company emphasizes authenticity and quality, leveraging partnerships with recognized brands like AMG and BRABUS. The website supports multiple languages and offers extensive product catalogs with detailed descriptions and FAQs, enhancing customer engagement. Payment and shipping partnerships with major carriers and payment providers add to its credibility. Social media presence and CO2 neutral certification further strengthen brand trust. The company appears medium-sized with a stable market position in the niche of automotive tuning parts.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, use of Cloudflare CDN and security services, and presence of key security headers such as HSTS, X-Frame-Options, and Content-Security-Policy. The domain is protected against unauthorized transfers with clientTransferProhibited status. However, DNSSEC is not enabled, which is a recommended improvement. No security.txt or explicit incident response contacts are published, which could hinder vulnerability reporting. Forms appear secure with no visible vulnerabilities or exposed sensitive data. Overall, the security measures are robust but could be enhanced with DNSSEC and formal security policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement a cookie consent banner/mechanism to comply fully with GDPR and ePrivacy regulations.
  3. Publish a formal security policy and incident response contact information on the website.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure.
  5. Regularly review and audit third-party scripts and dependencies for security vulnerabilities.

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.
