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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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. 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

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 operates in the education and hospitality sectors, focusing on flexible room rental services for seminars, workshops, and meetings. Its market position is strengthened by awards and positive client feedback. The business model revolves around providing physical spaces with modern amenities and online reservation capabilities. The target audience includes corporate clients, educational providers, and trainers primarily within Switzerland. The website's content and branding are consistent and professional, supporting a small-sized enterprise with a local focus. Partnerships with Webtech AG for website development and presence on multiple social media platforms enhance its digital footprint.

Security posture

The website employs HTTPS and integrates Cookiebot for cookie consent, reflecting attention to privacy and security compliance. However, no explicit security policy or incident response information is published, and some recommended security headers are missing. Forms use POST methods, and no sensitive data exposure was detected in the HTML. The absence of a vulnerability disclosure policy or security.txt file suggests room for improvement in transparency and incident handling readiness. Overall, the security posture is solid but could benefit from enhanced header configurations and published policies.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and incident response procedures.
  2. Implement additional HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and Referrer-Policy.
  3. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Maintain and regularly update third-party scripts and CMS to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, ensuring scalability and maintainability. Integration with Google Tag Manager and Cookiebot indicates a modern approach to analytics and privacy compliance. The site uses Bootstrap-based responsive design for mobile optimization and includes JavaScript-driven UI components like carousels. Performance is moderate, with compressed CSS and JS assets served. No major technical debt or deprecated technologies were detected. Opportunities exist to improve accessibility and security header implementation to align with best practices.
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.
