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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

logo.de is positioned as a trusted children’s news source under the ZDF umbrella, leveraging the reputation of a large public broadcaster. Its competitive advantage lies in its tailored content for children, combining news with educational and interactive features. The business model is non-commercial public media, funded by public broadcasting fees. The target customers are children and youth in Germany. The site shows signs of maturity and stability, with consistent branding and comprehensive content. Partnerships appear limited to internal ZDF domains. Growth indicators include frequent content updates and multimedia integration. The site operates in the media sector with a focus on education and youth engagement.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented, reducing common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy or incident response contact limits transparency in security governance. There is no evidence of a vulnerability disclosure program or security.txt file. Privacy policies and cookie consent mechanisms are well implemented, supporting GDPR compliance. Overall, the site is secure for its audience but could improve by publishing explicit security and incident response information.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency by including data retention policies and more detailed privacy compliance information.
  5. Continue maintaining modern technology stack and security headers to uphold strong security posture.

Technical notes

Notes

The site is built using Next.js, a React-based framework, indicating a modern and scalable architecture. It uses optimized images with responsive srcsets and lazy loading for performance. The presence of multiple CSS files and JavaScript chunks suggests modular design. Hosting appears to be managed by ZDF, with name servers ns01.zdf.de and ns02.zdf.de. The site is mobile-optimized with viewport meta tags and responsive images. SEO is supported by canonical links, meta descriptions, and Open Graph tags. Accessibility is addressed with ARIA roles and labels. No deprecated or vulnerable libraries were detected. Performance is likely fast given the use of modern frameworks and image optimizations. Technical risks are minimal but monitoring for library updates and security patches is recommended.
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.
