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

9 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 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';…

  2. GDPR outside view

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

    • 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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

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 holds a strong position in the regional helicopter transportation and pilot training market in Switzerland. Their business model focuses on diversified helicopter services including passenger flights, specialized work flights, and a flight school, targeting both private customers and corporate clients. The presence of a dedicated safety management page and long operational history indicate a mature operational framework. Partnerships with reservation systems and flight briefing providers enhance operational efficiency. The company leverages social media actively to engage customers and promote services. Revenue streams likely include flight bookings, training fees, and voucher sales. The business targets affluent individuals, tourists, and aviation professionals in Central Switzerland. Growth potential exists in expanding flight school offerings and corporate contracts.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is properly implemented, and no sensitive data is exposed in the HTML content. Forms use POST methods, reducing risk of data leakage. However, no advanced security headers such as Content-Security-Policy or X-Frame-Options are detected, which could improve protection against common web attacks. There is no public incident response or vulnerability disclosure information, which limits transparency in security management. Privacy compliance is partial, with no cookie consent mechanism and limited GDPR details. The use of third-party analytics introduces moderate tracking risk. Overall, the security posture is adequate for the business size but could be enhanced with additional controls and transparency.

Recommendations

  1. Implement a cookie consent banner to comply with privacy regulations and improve user trust.
  2. Enhance the privacy policy to explicitly address GDPR compliance and data protection practices.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Publish incident response and vulnerability disclosure policies to improve security transparency.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy and security risks.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and extensible content management system. It uses jQuery and integrates Google Analytics and Google Tag Manager for analytics and marketing. The site loads CSS and JavaScript assets efficiently, though performance is moderate rather than fast, possibly due to multiple scripts and media content. The site is mobile-optimized with responsive design elements and accessible navigation menus. SEO is supported by proper meta tags and Open Graph tags. There is no evidence of outdated or vulnerable libraries. Hosting details are not explicit but the site uses HTTPS with a valid certificate. Opportunities exist to improve performance by optimizing media and reducing third-party script load. Accessibility is basic but could be enhanced with ARIA roles and better keyboard navigation support.
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.
