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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Facebook

      What to do: Document all third-party data sharing in your privacy policy

  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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The project occupies a niche cultural heritage and tourism market with a clear focus on the Upper Rhine castles. Its competitive advantage lies in European funding, regional government support, and a comprehensive digital presence including events, research, and interactive content. The business model is public sector driven, emphasizing cultural preservation and tourism promotion rather than commercial revenue. The target audience includes tourists, historians, and local communities interested in medieval heritage. The partnership ecosystem includes regional authorities and cultural organizations. Growth indicators include ongoing events and research activities, with a strong branding consistency and trust signals such as awards and official logos.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, no visible sensitive data exposure, and a cookie consent banner aligned with GDPR requirements. However, it lacks several recommended security headers (e.g., CSP, HSTS) and does not publish a security policy or vulnerability disclosure information. Incident response readiness is not publicly documented. No vulnerabilities or suspicious patterns were detected in the content or scripts. The use of Matomo analytics indicates a privacy-conscious approach to user tracking. Overall, the security posture is good but could be enhanced by implementing additional headers and transparency measures.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and vulnerability disclosure page to improve transparency and incident response readiness.
  3. Add a security.txt file at the root domain to facilitate responsible vulnerability reporting.
  4. Consider providing direct contact information such as a dedicated security or abuse email address.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern technology stack with Alpine.js for interactivity, Splide.js for carousels, and FontAwesome for icons. It is built on the Umbraco CMS platform, which is a robust enterprise-grade CMS. The site loads asynchronously some scripts and preloads fonts and stylesheets for performance optimization. Mobile responsiveness and accessibility are well addressed with skip links and semantic HTML. SEO is supported by comprehensive meta tags, Open Graph, and JSON-LD structured data describing the organization and content. The hosting provider is not explicitly identified. Performance is moderate, with room for improvement in caching and security headers. Overall, the technical implementation supports a professional and user-friendly experience.
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.
