Bikeschule Klosters is a well-established mountain bike school located in Klosters/Davos, Switzerland, with a history dating back to 1931. The company offers a broad range of bike courses, camps, workshops, and private guiding services tailored for children, youth, and adults. Their business model focuses on experiential outdoor education and recreation, supported by an online booking platform. The website reflects a professional and consistent brand image with clear contact information and partner affiliations, positioning them as a trusted local service provider in the biking community. Technically, the website is built on TYPO3 CMS, utilizing modern web technologies such as jQuery, Owl Carousel, and Google Tag Manager for analytics. The site is mobile-optimized with good SEO practices and basic accessibility features. Performance is moderate, with compressed assets and responsive design elements enhancing user experience. From a security perspective, the site enforces HTTPS with IP anonymization for analytics and a comprehensive cookie consent mechanism. However, it lacks explicit security headers and publicly available security or incident response policies. No vulnerabilities or exposed sensitive data were detected, indicating a solid security posture for a small business. Overall, the website is safe, professional, and trustworthy, with no adult or questionable content. The domain registration data aligns well with the business claims, reinforcing legitimacy. Strategic improvements could focus on enhancing security headers, publishing security policies, and expanding incident response transparency to further strengthen trust 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

7 findings rated critical or high. Fix these first.

  1. Network security

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

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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"

      • 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

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 · found on this site
  • 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

Bikeschule Klosters operates in the outdoor recreation and education sector, targeting families, children, and adult biking enthusiasts. Their competitive advantage lies in their long-standing presence since 1931, diverse course offerings, and integration with local tourism and ski school partners. Revenue streams primarily come from course bookings and private guiding services. The company leverages online booking and digital marketing tools to reach its audience. Partnerships with local organizations and tourism bodies enhance their market presence. Growth indicators include new full-day courses for children and active event participation. The business ecosystem is community-focused with strong regional ties.

Security posture

The website demonstrates a mature security posture for a small business, with HTTPS enforced and privacy-conscious analytics implementation. The cookie consent mechanism is robust, allowing granular user choices. However, the absence of advanced security headers like Content-Security-Policy and lack of published security policies or incident response contacts represent gaps. No signs of vulnerabilities or data leaks were found. Compliance with GDPR is indicated by the privacy and cookie policies. Incident response readiness is unclear due to missing contact channels. Overall, the security culture appears adequate but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement and publish a formal security policy and incident response plan on the website.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve protection against common web attacks.
  3. Provide clear contact channels for security incidents, e.g., security@ or abuse@ email addresses.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.
  5. Enhance accessibility features to meet higher standards and improve user inclusivity.

Technical notes

Notes

The website is powered by TYPO3 CMS, a mature and extensible content management system. It uses jQuery and Owl Carousel for interactive UI elements and Google Tag Manager for analytics integration. The site assets are compressed and served efficiently, contributing to moderate performance. Mobile optimization is good, with responsive images and layouts. SEO is supported by proper meta tags and canonical links. The technical stack is modern but could be improved by adopting newer JavaScript frameworks and enhancing accessibility compliance. Hosting details are not explicitly identified, but the presence of HTTPS and external resource loading indicates a professionally managed environment.
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.
