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. 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

  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';…

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 operates as a medium-sized public educational entity focused on secondary education and vocational training in fields such as culinary arts, mechanical work, and caregiving. Its business model is non-commercial, funded likely by regional government and public sources. The website reflects a strong community and partnership ecosystem with local government, educational organizations, and industry partners. The presence of official contact information, partner logos, and structured data enhances credibility. Growth indicators include active social media presence and digital tools like virtual tours. The school targets students and parents in the region, emphasizing practical and academic education.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent implemented. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of security headers and public security or incident response policies indicates room for improvement. GDPR compliance is suggested by cookie consent and privacy policy presence but lacks explicit documentation on data protection officers or incident contacts. The use of common WordPress plugins necessitates regular updates to mitigate potential vulnerabilities. Overall, the security posture is adequate for an educational institution but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish explicit security and incident response policies on the website to increase transparency and preparedness.
  3. Regularly update WordPress core and all plugins to the latest versions to reduce vulnerability risks.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Enhance accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress 5.5.17 with jQuery and uses Google Analytics and Tag Manager for tracking. Fonts are loaded via Adobe Typekit. The site includes a cookie consent plugin that supports GDPR compliance. Performance is moderate with no major issues detected, and the site is mobile-optimized with responsive design. SEO is supported by Yoast SEO plugin with proper meta tags and structured data in JSON-LD format. No advanced frameworks or hosting provider details were identified. The technical stack is standard for educational websites but would benefit from modernization and enhanced security configurations.
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.
