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

Bertelsmann SE & Co. KGaA is a leading international media conglomerate headquartered in Germany, operating across multiple sectors including broadcasting, book publishing, music, services, printing, education, and investments. The website reflects a mature corporate presence with comprehensive information targeting investors, journalists, job seekers, and the general public. The business model is diversified with strong subsidiaries such as RTL Group and Penguin Random House, positioning Bertelsmann as a major player in the global media industry. Technically, the website employs established web technologies like Bootstrap and jQuery, with content delivery via Amazon CloudFront CDN, ensuring good performance and mobile optimization. However, the absence of a valid SSL certificate and HTTPS support significantly undermines the security posture. Security headers are partially implemented, but critical HTTPS and TLS configurations are missing, exposing the site to potential risks. Privacy compliance is well addressed with a comprehensive privacy policy and cookie consent managed by Cookiebot. Contact information and social media presence are clearly provided, enhancing business credibility. Overall, the site is professional and content-rich but requires urgent security improvements to meet modern standards.

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. 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

    • 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

  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

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

Bertelsmann maintains a strong market position as a diversified media company with multiple well-known subsidiaries. Its business model leverages content creation, distribution, and investment platforms to generate revenue streams across media and education sectors. The website's investor relations and compliance sections indicate a transparent corporate governance approach. The company targets a broad audience including investors, media professionals, and potential employees. The partnership ecosystem includes related domains and services supporting career development and social media engagement. Growth indicators are visible through recent news and financial reports. The strategic use of marketing and analytics tools suggests a data-driven approach to audience engagement. The absence of incident response contacts or vulnerability disclosure mechanisms may indicate an area for future enhancement in corporate security communication.

Security posture

The current security posture of the website is weak due to the lack of a valid SSL certificate and absence of HTTPS support, which is a critical vulnerability for any modern website, especially one handling user data and corporate information. While some security headers like Content Security Policy and X-Content-Type-Options are implemented, the missing TLS protocols and HSTS configuration expose the site to potential man-in-the-middle attacks and downgrade vulnerabilities. The use of HttpOnly cookies is a positive practice. No known vulnerabilities such as Heartbleed or POODLE were detected, but the overall lack of encryption significantly reduces trust and security. The site does not provide explicit incident response contacts or vulnerability disclosure policies, which are important for security maturity. Immediate remediation of SSL/TLS issues is recommended to protect user data and corporate assets.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable and enforce modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Enable OCSP stapling to improve certificate revocation checking performance and security.
  5. Establish and publish an incident response contact and vulnerability disclosure policy to enhance security transparency and readiness.

Technical notes

Notes

The website uses a traditional tech stack with jQuery 1.9.1 and Bootstrap for responsive design, supported by Font Awesome icons and Plyr for media playback. Cookiebot manages cookie consent, integrating with Google Tag Manager and Google Analytics for marketing and analytics purposes. Hosting is via Amazon CloudFront CDN, providing global content delivery. The site is mobile optimized with responsive images and viewport settings. However, the lack of HTTPS and modern TLS protocols is a significant technical debt and security risk. Performance metrics were not provided, but the use of CDN and optimized images suggests moderate to good performance. Accessibility features are basic, with room for improvement. SEO is supported by comprehensive meta tags and Open Graph data. Overall, the technical infrastructure is functional but requires modernization in security protocols and potential CMS or framework upgrades.
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.
