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

The website grundschuldiagnose.westermann.de is a professionally developed educational platform operated by the Westermann Gruppe, targeting German primary school educators with online diagnostic tests and differentiated learning materials for German and Mathematics. The platform offers subscription-based licenses for classes, schools, and school districts, supported by a centralized student management system and integration with partner educational services. The site is built on TYPO3 CMS with modern frontend technologies, providing a responsive and accessible user experience. Security posture is solid with HTTPS enforced, but lacks explicit security headers and published security policies. Privacy compliance is partial, with a clear privacy policy but no cookie consent mechanism detected. Contact information is clearly provided, and the site holds a child-safe certification (fragFINN). Overall, the site is trustworthy, well-branded, and serves a clear educational niche.

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

8 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

Westermann Gruppe leverages its established position in the German educational publishing market to provide digital diagnostic tools that complement traditional learning materials. The business model is license-based, targeting schools and educators with scalable offerings from class licenses to school district licenses. The platform's integration with partner sites like alfons.de and antolin.de indicates a strategic ecosystem approach to educational content delivery. The site’s detailed documentation and professional design support strong market credibility. Growth potential lies in expanding interactive online exercises and centralized management features.

Security posture

The website demonstrates a good security baseline with HTTPS and secure login mechanisms. However, the absence of security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces defense-in-depth. No incident response or vulnerability disclosure information is published, which could hinder rapid response to security events. No tracking or analytics scripts were detected, reducing privacy risks. The site should improve cookie consent compliance and publish security policies to enhance trust and regulatory adherence.

Recommendations

  1. Implement and enforce security headers (CSP, HSTS, X-Frame-Options) to strengthen security posture.
  2. Add a cookie consent banner/mechanism to comply with GDPR and ePrivacy Directive requirements.
  3. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  4. Consider adding a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The site uses TYPO3 CMS, jQuery 3.5.1, and Bootstrap for frontend responsiveness and UI components. The HTML is well-structured with appropriate meta tags for SEO and mobile viewport settings. Performance is moderate, with responsive images and adaptive layouts. Accessibility is basic but could be improved with ARIA roles and better keyboard navigation support. No analytics or tracking scripts were found, indicating minimal user tracking. Hosting provider details are not explicit in the content. Overall, the technical implementation is modern and stable but could benefit from enhanced accessibility and security header implementation.
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.
