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
      • 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

SAT.1 operates in the media sector as a large entity under the ProSiebenSat.1 Media SE umbrella. It leverages partnerships with streaming platforms like Joyn to distribute content digitally. The business model focuses on broadcasting, content creation, and digital streaming services. The website's content and structure reflect a mature digital presence with rich multimedia content, targeting a broad German-speaking audience. The company maintains a consistent brand image and integrates privacy compliance tools, indicating awareness of regulatory requirements. The partnership ecosystem includes Joyn as a key streaming partner, enhancing content reach and user engagement.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and privacy consent mechanisms in place. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not visible and should be verified or implemented to enhance protection against common web attacks. There is no public incident response or security policy information found, which could be improved to increase transparency and readiness. Overall, the site follows good security practices but could benefit from additional header configurations and published security policies.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish clear security and incident response policies accessible to users and security researchers.
  3. Enhance transparency by providing explicit contact information for security incidents or data protection inquiries.
  4. Regularly audit third-party scripts and embedded content for vulnerabilities and privacy compliance.
  5. Maintain and update privacy consent mechanisms in line with evolving GDPR and ePrivacy regulations.

Technical notes

Notes

The website is built using modern web technologies, primarily Next.js and React, which enable server-side rendering and fast client-side interactions. Styling is managed via Emotion CSS-in-JS, providing modular and maintainable styles. The site uses Swiper.js for interactive carousels and integrates Usercentrics for privacy consent management. Performance appears optimized with preloading of key assets and responsive design for mobile devices. No CMS is explicitly detected, suggesting a custom or proprietary content management solution. Hosting details are not explicit but nameservers indicate a branded hosting environment. Overall, the technical infrastructure supports a high-quality user experience with opportunities to enhance security headers and public documentation.
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.
