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

The website www.wdrmaus.de is the official online presence of the German public broadcaster Westdeutscher Rundfunk's children's program 'Die Sendung mit der Maus'. It provides educational and entertaining content for children including videos, games, crafts, and audio stories. The site is well-branded and professionally designed, targeting a young audience with a focus on learning and fun. The business model aligns with public media educational services, positioning it as a trusted and established media brand in Germany. Technically, the site uses a modern JavaScript stack including jQuery, CreateJS, and ARD's custom media player. The infrastructure appears stable and moderately performant with good mobile optimization and accessibility features. SEO and metadata are well implemented, supporting discoverability and social sharing. Hosting is likely managed by WDR or its partners, with domain name servers consistent with the organization. From a security perspective, the site uses HTTPS and avoids exposing sensitive data. However, no explicit security headers were detected in the HTML source, and there is no visible cookie consent mechanism despite the use of tracking analytics (Piano). No security or incident response policies are published, and contact is limited to a web form without direct email or phone contacts. Overall, the security posture is moderate but could be improved with better header policies and transparency. The site is safe for general audiences, especially children, with no adult or questionable content detected. The domain WHOIS data aligns with the WDR organization, supporting legitimacy. The overall risk is low, but recommendations include adding cookie consent, security headers, and publishing security policies to enhance compliance and trust.

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.

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. 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 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. 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

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

Westdeutscher Rundfunk operates this site as part of its public broadcasting mandate, focusing on children's educational content. The site leverages WDR's strong brand and media production capabilities to deliver engaging multimedia content. The business model is non-commercial, funded by public broadcasting fees, emphasizing educational value over revenue. The target audience is children and families in Germany. The site integrates with WDR's broader digital ecosystem, linking to related domains and services. Growth indicators include regular content updates and interactive features. Partnerships appear internal within WDR's media group. The site maintains a high level of professionalism and trust consistent with public media standards.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is used, and no sensitive data leaks are evident. The use of modern JavaScript libraries is current, reducing vulnerability risks. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces defense-in-depth. The lack of a cookie consent mechanism conflicts with GDPR best practices given the use of tracking analytics. No published security or incident response policies limit transparency and preparedness. Contact channels for security issues are not provided. Overall, the site is secure for its purpose but would benefit from enhanced security controls and compliance documentation.

Recommendations

  1. Implement and display a cookie consent banner to comply with GDPR and inform users about tracking.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection.
  3. Publish a dedicated security policy and incident response contact information to increase transparency and readiness.
  4. Provide direct contact details such as security@ or abuse@ email addresses for reporting security incidents.
  5. Regularly audit third-party scripts and tracking tools to ensure no vulnerabilities or privacy issues.

Technical notes

Notes

The website uses a custom or proprietary CMS or framework with a modern JavaScript tech stack including jQuery, CreateJS, Flexslider, and ARD's media player. The site is well-structured with semantic HTML and meta tags supporting SEO and social sharing. Performance is moderate with some heavy media content but generally optimized for desktop and mobile. Accessibility features such as skip links and labels are present. No major technical debt or deprecated libraries were detected. Hosting appears stable and integrated with WDR infrastructure. Opportunities exist to modernize further with enhanced security headers and cookie management.
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.
