Schweizer Skischule Lenk is an official ski school located in the Adelboden-Lenk ski region of Switzerland, offering ski and snowboard lessons for all skill levels, including specialized children's courses and winter events. The business is positioned as a local expert in winter sports education, targeting ski enthusiasts and families visiting the Berner Oberland region. Their business model is service-oriented with online booking capabilities, supported by a professional and consistent brand presence. Technically, the website is built on TYPO3 CMS with modern JavaScript libraries such as jQuery and Owl Carousel. It employs HTTPS with anonymized IP tracking in Google Analytics and includes a cookie consent mechanism compliant with GDPR. The site demonstrates good mobile optimization and SEO practices, although some security headers are missing, which could be improved. From a security perspective, the site uses HTTPS and cookie consent but lacks explicit security policies or incident response information. No vulnerabilities or exposed sensitive data were detected. The domain registration is consistent with the business location and claims, enhancing trustworthiness. Overall, the website is secure, compliant, and professionally maintained. The overall risk is low, with recommendations focusing on enhancing security headers, adding incident response details, and maintaining up-to-date third-party libraries to further strengthen security posture and compliance.

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

5 findings 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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 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';…

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 ski school operates in the hospitality sector, focusing on winter sports education in a well-known Swiss ski region. Its competitive advantage lies in official recognition and a comprehensive offering of ski and snowboard lessons, including family and children-friendly programs. Revenue streams are primarily from course bookings and event participation, facilitated through an online shop. The target customers are local and visiting ski enthusiasts of all ages and skill levels. The company maintains active social media channels and integrates customer trust signals such as Tripadvisor reviews. Growth potential is tied to tourism trends in the region and expanding digital booking capabilities. Partnerships with local ski resorts and event organizers are implied but not explicitly detailed. The business maintains a clear and professional online presence, supporting customer engagement and trust.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced with anonymized IP tracking in analytics, and a GDPR-compliant cookie consent mechanism is implemented. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. There is no visible security or incident response policy, which is a gap in compliance and readiness. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of third-party libraries like jQuery and Owl Carousel should be monitored for updates to mitigate potential risks. The domain registration details are consistent and transparent, supporting trustworthiness. Incident response contact channels are not provided, which could delay response to security incidents.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response plan accessible on the website to improve transparency and readiness.
  3. Regularly update all third-party libraries and CMS components to mitigate vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Maintain and monitor cookie consent mechanisms to ensure ongoing GDPR compliance and user privacy.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a mature technical infrastructure. It uses jQuery and Owl Carousel for interactive elements and Google Analytics for traffic analysis. The site is served over HTTPS with a favicon and responsive design elements, supporting good user experience across devices. Performance is moderate, with compressed CSS and JS assets, but could benefit from further optimization. Accessibility is basic, with room for improvement in ARIA roles and keyboard navigation. SEO is well addressed with meta descriptions, canonical links, and hreflang tags for multilingual support. No hosting provider details were found in the content, limiting infrastructure insights.
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.
