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

3 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…
  2. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

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

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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.

Add-on

Leaked records that mention mittelthurgau.ch, from OffSeq Breach.

No leaked records found

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 holds a strong market position within the hospitality and transportation sectors, particularly in the niche of river cruises. It operates under the parent company Twerenbold Reisen Gruppe, indicating a stable corporate structure. The business model revolves around curated travel experiences with a focus on sustainability and quality. The website's integration with multiple marketing and analytics platforms suggests a data-driven approach to customer engagement and growth. Partnerships with domains like imbach.ch and gamification services indicate active marketing strategies. The clear presentation of terms, privacy policies, and contact details supports a professional and customer-centric approach.

Security posture

The website maintains a good security baseline with HTTPS and cookie consent compliance. Use of Cloudflare services provides additional protection against bots and DDoS attacks. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident, which could enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The extensive use of third-party scripts necessitates ongoing monitoring to mitigate supply chain risks. Incident response and vulnerability disclosure policies are not publicly documented, representing an area for improvement.

Recommendations

  1. Implement and enforce security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a clear incident response and vulnerability disclosure policy to improve transparency and readiness.
  3. Regularly audit third-party scripts and dependencies to prevent supply chain vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website is built on Concrete5 CMS with a modern frontend stack including Vue.js and jQuery. It uses Axios for API calls and integrates multiple analytics and marketing tools such as Google Tag Manager, Hubspot, Mouseflow, and Facebook Pixel. Hosting and CDN services appear to be provided via Cloudflare, enhancing performance and security. The site is mobile-optimized with responsive design and preloaded web fonts for performance. SEO is supported by comprehensive meta tags and Open Graph data. Performance is moderate, with potential for optimization by reducing third-party script load and improving caching strategies. The technical infrastructure is robust but could benefit from enhanced security header implementation and accessibility improvements.
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.
