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

Seven.One Entertainment Group GmbH is a leading German media and entertainment company specializing in TV broadcasting, streaming, advertising products, content production, and event and artist management. It operates multiple well-known TV and digital brands and is a subsidiary of ProSiebenSat.1 Media SE. The website demonstrates a mature digital presence with modern technologies such as Liferay CMS, React, and integrated marketing and consent management tools. However, a critical security weakness is the absence of a valid SSL certificate, exposing users to potential risks. The company maintains comprehensive privacy and cookie policies with GDPR compliance and uses consent-based tracking. Overall, the business is positioned strongly in the German media market with a broad portfolio and professional digital infrastructure but needs urgent improvements in security configuration.

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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

The company holds a strong market position in the German media sector, offering a wide range of entertainment and advertising services. Its business model revolves around content creation, distribution, and monetization through advertising and partnerships. The presence of multiple subsidiaries and partner domains indicates a diversified portfolio and strategic ecosystem. The target audience includes advertisers, media buyers, and entertainment consumers. The company leverages advanced marketing tools and tracking technologies while maintaining compliance with privacy regulations. Growth indicators include recent news about partnerships and expansions in audio and digital content. The company emphasizes creative storytelling and integrated marketing solutions, positioning itself as a comprehensive media partner.

Security posture

The current security posture shows moderate maturity with valid SPF and DMARC DNS records and active domain verifications for various services. However, the lack of a valid SSL certificate and absence of HTTPS enforcement is a significant vulnerability that undermines user trust and data security. No DNSSEC or CAA records are present, increasing risks related to DNS spoofing and unauthorized certificate issuance. The website lacks security headers and HSTS policies, which are standard best practices. Incident response and security policy information are not publicly available, indicating potential gaps in transparency and readiness. The company uses consent management platforms to comply with GDPR but should urgently address transport layer security to protect user data and maintain compliance.

Recommendations

  1. Immediately install and maintain a valid SSL/TLS certificate to enable HTTPS across the site.
  2. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Deploy DNSSEC and CAA DNS records to enhance DNS security and certificate issuance control.
  4. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Publish clear security and incident response policies and provide dedicated security contact channels.

Technical notes

Notes

The website is built on Liferay CMS with React and uses a variety of JavaScript libraries and frameworks. It integrates marketing and analytics tools including Google Tag Manager, Usercentrics CMP, HubSpot, and LinkedIn Insight Tag. The DNS configuration includes multiple TXT records for domain verification and SPF for email protection. Performance is moderate with a page load time of approximately 6 seconds and a page size of about 588 KB. Mobile optimization is good, and SEO practices are well implemented with canonical and hreflang tags. However, the absence of SSL/TLS and security headers represents a critical technical debt. Hosting provider details are not explicit but IP addresses suggest cloud hosting. The site uses extensive tracking and marketing scripts controlled by user consent.
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.
