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

3sat is a well-established public broadcasting media platform serving the German-speaking audience with a focus on cultural, scientific, and societal content. The website offers video streaming, livestreams, documentaries, and magazines, positioning itself as a trusted source for quality media content. The platform is technically mature, leveraging modern web technologies, a robust consent management system, and a fast, mobile-optimized user experience. Security posture is strong with HTTPS enforcement, secure hosting via Akamai, and no visible vulnerabilities. Privacy compliance is well implemented with clear GDPR-aligned policies and cookie consent mechanisms. However, explicit security policies and incident response contacts are not publicly available, representing an area for improvement.

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

      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

      • 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

3sat operates as an essential media entity within the public broadcasting sector, supported by ZDF. Its business model centers on free-to-access cultural and educational content, targeting a broad German-speaking demographic interested in documentaries, science, and societal issues. The platform benefits from strong brand consistency, trust signals such as official contact information and structured data, and partnerships with ZDF. The content quality and user engagement features like personalized recommendations and playlists indicate a mature digital presence. Growth opportunities may include enhanced security transparency and expanded incident response readiness.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, use of reputable hosting and CDN providers (Akamai), and implementation of a comprehensive consent management platform. No exposed sensitive data or vulnerable libraries were detected. The absence of a published security policy or vulnerability disclosure program suggests room for strengthening transparency and incident readiness. Overall, the security posture supports the platform's trustworthiness and compliance with data protection regulations.

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 publicize a vulnerability disclosure policy or security.txt file.
  4. Regularly audit third-party scripts and tracking tools to ensure no vulnerabilities.
  5. Enhance transparency around data retention policies and user data handling.

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.
