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. 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. 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

  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 school occupies a niche in the Danish education sector as a folk high school with a focus on arts and culture. Its business model centers on providing residential educational programs and short courses, targeting students who value creative freedom and intellectual exploration. The website's integration with social media and event promotion indicates active community engagement and marketing efforts. The use of third-party services like CookieInformation.com for consent management and Cloudflare for hosting and security suggests a strategic approach to compliance and infrastructure. The absence of parent or subsidiary companies implies an independent operation. The school's longevity and domain age provide competitive advantage and market credibility.

Security posture

The website exhibits a mature security posture with HTTPS enabled and Cloudflare providing CDN and DDoS protection. The cookie consent banner is detailed and allows granular user control, supporting GDPR compliance. However, some standard security headers like Content-Security-Policy and X-Frame-Options are not explicitly detected and could be improved. No exposed sensitive data or vulnerable libraries were found in the HTML content. The use of trusted third-party analytics and marketing tools is balanced with privacy considerations. Incident response and security policy documentation are not publicly available, representing an area for enhancement.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing
  2. Implement additional HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options
  3. Publish a clear security policy and incident response plan accessible on the website
  4. Regularly audit and update third-party scripts and plugins to mitigate vulnerabilities
  5. Enhance accessibility features to improve compliance and user experience for all users

Technical notes

Notes

The website is powered by WordPress with a modern tech stack including jQuery and Google services. It uses Cloudflare for CDN and security, which improves performance and resilience. The site is mobile optimized and SEO friendly with proper meta tags and structured data (JSON-LD). The presence of multiple embedded Vimeo videos and Instagram feeds indicates rich media usage, which may impact load times but enhances engagement. Cookie consent is managed via CookieInformation.com, integrating Google Consent Mode. The site uses Contact Form 7 for forms, which is a widely used and supported plugin. Overall, the technical implementation is solid but could benefit from enhanced security headers and performance tuning.
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.
