KG is a well-established German media company specializing in film and television production services, corporate media, live broadcasting, and innovative media solutions including VR/AR and 360° films. As part of the Madsack Mediengruppe, it leverages over 40 years of industry experience and offers a comprehensive portfolio of services to media professionals and corporate clients. The company maintains a strong market position with diversified competencies and a focus on technical and content innovation. Technically, the website is built on TYPO3 CMS with modern JavaScript libraries such as jQuery, Bootstrap, and Slick Carousel. It integrates Matomo analytics and a consent management platform to ensure GDPR compliance. Hosting appears to be stable and professional, likely provided by Deutsche Telekom. The site is mobile-optimized and SEO-friendly, with good accessibility and performance characteristics. From a security perspective, the website enforces HTTPS and uses a consent management platform for privacy 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

6 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 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';…

  2. GDPR outside view

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

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

TVN GROUP operates in the media sector with a focus on production and corporate communication services. Its competitive advantage lies in its broad and specialized service portfolio, technical innovation, and integration within the Madsack Mediengruppe. The business model centers on providing end-to-end media production and live broadcasting solutions to broadcasters, corporate clients, and content creators. Revenue streams likely include service contracts for production, live events, corporate media campaigns, and specialized media technology solutions. The company targets media professionals and corporate clients seeking high-quality media production and communication services. Its partnership ecosystem includes subsidiaries like TVN CORPORATE MEDIA and the parent company Madsack Mediengruppe, enhancing market reach and resource sharing. Growth indicators include diversified service offerings and investment in emerging media technologies such as VR/AR. Strategic observations highlight a strong emphasis on innovation, quality, and comprehensive service delivery.

Security posture

The security maturity level of the TVN GROUP website is moderate to high. HTTPS is enforced, and a consent management platform is integrated to comply with GDPR. The site avoids exposing sensitive data and uses modern libraries with deferred script loading to reduce attack surface. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and preparedness. No known vulnerabilities or security misconfigurations were detected in the provided content. Compliance with GDPR is evident through privacy and cookie policies and consent mechanisms. Incident response readiness and security culture indicators are not publicly visible, which could be enhanced to build greater trust. Overall, the security posture supports business operations but would benefit from formalized security documentation and communication.

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. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a mature technical infrastructure. It uses modern JavaScript libraries including jQuery, Bootstrap, and Slick Carousel for UI components and responsiveness. The integration of Matomo analytics and a custom consent management platform demonstrates attention to privacy and data protection. Hosting appears to be stable and professional, likely provided by Deutsche Telekom, as inferred from the nameservers. Performance is moderate with deferred script loading and video background elements. Mobile optimization is good, with responsive navigation and language options. Accessibility is basic but present. SEO optimization is good with proper meta tags, canonical links, and structured data. Technical risks are minimal but could be reduced further by implementing additional security headers and formal policies.
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.
