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

Auer.lu is an e-commerce platform specializing in the online retail of watches, positioned as the largest specialist in the horology sector online within its market. The business operates under the umbrella of Holland Watch Group B.V., a recognized entity in the watch retail industry. The website targets primarily French-speaking consumers in Luxembourg and the Netherlands, offering official brand watches with fast delivery services. Technically, the site employs modern web technologies including Alpine.js, Tailwind CSS, and integrates Google Analytics and Tag Manager for tracking. The presence of privacy and cookie policies with consent mechanisms indicates a good level of privacy compliance. Security posture is solid with HTTPS and CSRF protections, though it lacks some advanced security headers. The absence of WHOIS data limits domain trust evaluation but the business branding and partner domains support legitimacy.

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.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

The company leverages a multi-lingual e-commerce model with a broad European reach, supported by a network of partner domains in various languages. Its competitive advantage lies in being an official reseller with a large stock and rapid delivery, targeting watch enthusiasts and consumers seeking trusted online purchases. The business model is retail-focused with revenue generated from direct sales. The partnership ecosystem includes multiple regional domains, enhancing market penetration. Growth indicators include a well-maintained website with customer ratings and trust widgets. Strategic observations suggest continued investment in digital marketing and customer experience to maintain market leadership.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, CSRF token usage, and secure form handling. However, it lacks several recommended HTTP security headers such as Content-Security-Policy and HSTS, which could improve protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy policies and cookie consent mechanisms align with GDPR requirements, though no explicit incident response or security policy documentation was found. Overall, the security maturity is good but could benefit from enhanced header configurations and formalized incident response channels.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and HSTS to strengthen web security.
  2. Publish a dedicated security policy and incident response information to improve transparency and readiness.
  3. Conduct regular audits of third-party scripts and dependencies to mitigate supply chain risks.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider publishing vulnerability disclosure and security.txt files to encourage responsible reporting.

Technical notes

Notes

The website uses a modern frontend stack with Alpine.js for interactivity and Tailwind CSS for styling, ensuring responsive design and good mobile optimization. Integration with Google Analytics and Tag Manager supports data-driven marketing. The site loads external fonts via Typekit and uses trusted third-party widgets for customer reviews. Performance is moderate with room for optimization. No CMS was explicitly detected, suggesting a custom or headless solution. Hosting provider details are not disclosed. Technical risks include reliance on multiple external domains and absence of some security headers. Overall, the infrastructure supports a professional e-commerce experience with opportunities for further technical enhancements.
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.
