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

Change Learning is a German educational project affiliated with the Bertelsmann Stiftung, focusing on transforming the school system into a learning-oriented environment that fosters participation, well-being, and equitable opportunities for children and youth. The website serves as a knowledge platform offering articles, project themes, awards, and publications aimed at educators, policymakers, and stakeholders in education. Technically, the site is built on WordPress with modern optimization plugins and uses HTTPS with moderate performance and good mobile optimization. Security posture is solid with HTTPS and secure forms but lacks explicit security headers and incident response information. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. Overall, the site is professional, trustworthy, and content-rich, with a strong brand association to Bertelsmann Stiftung.

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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 holds a strong market position as a non-profit educational initiative under the reputable Bertelsmann Stiftung. It targets education professionals and decision-makers interested in school transformation and democratic participation. The business model is knowledge dissemination and community engagement rather than commercial sales. The website's content quality and branding consistency support its credibility. Partnerships with Bertelsmann Stiftung and social media presence enhance its ecosystem. Growth indicators include regular publications and active social media channels. Revenue streams are not evident, consistent with a non-profit model.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and secure contact forms. However, it lacks visible security headers such as Content-Security-Policy and does not provide explicit security or incident response policies. No vulnerability disclosure or security.txt files are present. The absence of a cookie consent mechanism is a GDPR compliance gap. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is good but could be improved with additional policies and headers.

Recommendations

  1. Implement a GDPR-compliant cookie consent banner and mechanism.
  2. Add security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Publish a clear security policy and incident response contact information.
  4. Consider adding a vulnerability disclosure policy or security.txt file.
  5. Enhance accessibility features and provide more explicit contact information.

Technical notes

Notes

The website uses WordPress 6.7.4 with jQuery and Contact Form 7 for forms. CSS and JS are optimized via Autoptimize. The site uses eTracker for analytics, indicating moderate user tracking. The site is mobile optimized and has good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate, with no critical technical debt visible. Hosting provider details are not explicit. The site uses standard web technologies and modern best practices but could improve accessibility and security headers.
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.
