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

Seitenstark is a well-established German non-profit network providing a safe and educational internet environment for children. The website aggregates over 60 child-friendly sites offering diverse content such as games, knowledge, music, and interactive activities. It targets children primarily, with additional resources for parents and educators. The network emphasizes child safety and educational value, positioning itself as a trusted resource in the German child education sector. Technically, the site is built on Drupal CMS and employs modern JavaScript libraries including jQuery 3.7.1, lazy loading with Blazy, and multimedia support with Video.js. The site is mobile-optimized, accessible, and performs moderately well. Hosting is via DomainControl nameservers, indicating a professional hosting environment. SEO and metadata are well implemented, supporting discoverability. From a security perspective, the site uses HTTPS exclusively and loads external resources securely. However, it lacks explicit security headers and does not provide visible security policies or incident response contacts. Cookie usage is present but without a clear consent mechanism, which is a minor compliance gap. No vulnerabilities or exposed sensitive data were detected. Overall, Seitenstark presents a low-risk profile with strong content quality and a clear mission. Strategic improvements include implementing explicit cookie consent, publishing security and incident response policies, and providing clearer contact information to enhance trust and compliance.

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

7 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

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

Seitenstark operates as a non-profit educational network focused on child-safe internet content in Germany. Its market position is strong within the niche of child internet safety and education, leveraging partnerships with reputable child organizations like fragFINN and Kindersache. The business model centers on content curation and network collaboration rather than direct monetization. The target audience includes children, parents, and educators, with content designed to be safe, engaging, and educational. The network's extensive member sites and thematic diversity indicate a mature ecosystem with growth potential through increased digital engagement and partnerships. The absence of direct contact information and commercial elements suggests a focus on trust and safety over commercial gain. The website's technical maturity and content quality support its role as a leading resource in its sector.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and secure loading of external resources. The use of Drupal CMS and modern libraries indicates up-to-date technology, though no explicit security headers (e.g., CSP, X-Frame-Options) were detected in the provided content. There is no visible security policy or incident response information, which limits transparency and readiness perception. Cookie usage without explicit consent mechanisms presents a minor GDPR compliance risk. No vulnerabilities or sensitive data exposures were found in the HTML content. Recommendations include adding security headers, publishing a security policy, establishing incident response contacts, and implementing a cookie consent banner to enhance compliance and trust. Overall, the site is secure but could improve transparency and compliance documentation.

Recommendations

  1. Implement a clear cookie consent mechanism to comply with GDPR and enhance user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a dedicated security policy and incident response contact information on the website.
  4. Provide clear and accessible contact information for general and security inquiries.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on Drupal CMS with a modern JavaScript stack including jQuery 3.7.1, lazy loading (Blazy), and multimedia support (Video.js). It uses external CDNs and libraries loaded securely via HTTPS. The site is mobile-optimized and accessible, with good SEO metadata and structured navigation. Hosting is managed via DomainControl nameservers, indicating professional infrastructure. Performance is moderate, with potential improvements in caching and resource optimization. No technical debt or deprecated libraries were detected. The site lacks some advanced security headers and explicit privacy consent mechanisms, which are recommended for modernization and 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.
