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

4 findings rated critical or high. Fix these first.

  1. 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"

  2. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. DNS health

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

    • High

      Potential Subdomain Takeover

      Subdomain dev.gaultmillau.ch points to unregistered service ose-router-elb-378642568.eu-west-1.elb.amazonaws.com

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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 platform holds a strong market position as a trusted gastronomy guide in Switzerland, leveraging Ringier AG's media expertise. Its business model revolves around content publishing, advertising, and partnerships with premium brands such as Mercedes and UBS. The target audience includes food lovers and lifestyle consumers, with revenue likely generated through advertising, sponsored content, and possibly subscription services. The partnership ecosystem is robust, enhancing brand credibility and reach. Growth indicators include active social media presence and continuous content updates. The company maintains a consistent brand image and high content quality, supporting sustained market relevance.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and a consent management platform for cookies, aligning with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the absence of a publicly available security policy, incident response plan, or vulnerability disclosure program suggests areas for improvement in transparency and readiness. The use of multiple third-party scripts necessitates ongoing security audits to mitigate potential risks. Overall, the site maintains a secure environment appropriate for its business operations.

Recommendations

  1. Publish a dedicated security policy and incident response information to enhance transparency.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Regularly review and update third-party scripts and dependencies to mitigate vulnerabilities.
  4. Provide clear data retention policies and enhance privacy disclosures to strengthen GDPR compliance.
  5. Consider appointing and publicly listing a Data Protection Officer contact to improve trust.

Technical notes

Notes

The website is built on a modern technology stack featuring React and GraphQL, enabling dynamic content delivery and efficient data management. It integrates multiple advertising and tracking technologies, including Google Tag Manager, Prebid.js, and Piano paywall services, indicating a sophisticated monetization strategy. Performance is optimized with preloading, module preloading, and responsive images, ensuring fast load times and excellent mobile experience. The CMS appears custom or proprietary, tailored to Ringier's publishing needs. Accessibility and SEO practices are well implemented, supporting broad user reach and compliance. Technical risks are minimal but require vigilance on third-party script 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.
