0–100, higher is better. How it is calculated

The Nationale Onderwijsweek website serves as a central platform for promoting and organizing education-related events and initiatives in the Netherlands. It targets education professionals, schools, and the general public interested in education. The site highlights key programs such as the Nationale Onderwijsweek, Onderwijsstad, Onderwijstalenten, and the Nationale Onderwijsprijs, positioning itself as a recognized non-profit entity in the Dutch education sector. Technically, the website employs a modern tech stack including Bootstrap, jQuery, Google Analytics, and Font Awesome, ensuring a responsive and user-friendly experience with moderate performance. Security-wise, the site enforces HTTPS and uses cookie consent mechanisms but lacks advanced security headers and explicit security policies. Privacy compliance is basic with a clear privacy and cookie policy but no terms of service or vulnerability disclosure. Overall, the site is professional, trustworthy, and well-branded, though it could improve in security transparency and accessibility.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

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 organization behind the website is a small-sized non-profit focused on education awareness and event organization in the Netherlands. It leverages partnerships and media collaborations to amplify its reach. The business model centers on annual events and awards that celebrate education professionals and talents. The website's content and branding are consistent, supporting a strong market position within the Dutch education community. The presence of social media channels and partner logos indicates an active engagement strategy. However, no direct contact emails or phone numbers are publicly listed, relying on contact forms for communication. There is no indication of revenue streams or commercial activities, consistent with a non-profit profile.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and cookie consent implemented. However, it lacks several security best practices such as security headers (CSP, HSTS, X-Frame-Options) and does not provide explicit security or incident response policies. No vulnerability disclosure or security.txt files are present, which limits transparency for security researchers. The use of third-party scripts like Google Analytics and ShareThis introduces some tracking but no known vulnerabilities are evident. Overall, the security posture is adequate for a non-commercial informational site but could be enhanced to better protect user data and improve trust.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to comply with WCAG standards and improve user experience for all visitors.
  5. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a well-established front-end framework (Bootstrap) combined with jQuery and several JavaScript libraries for UI components like carousels and lightboxes. Fonts are loaded from Google Fonts and Fonts.net, and icons from Font Awesome. Analytics is handled via Google Analytics and ShareThis for social sharing. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. Performance is moderate, likely due to multiple external scripts and assets. No CMS or backend platform is explicitly detected. Hosting provider details are not available from the HTML content. The site could benefit from performance optimizations and enhanced accessibility compliance.
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.
