The corporate website reflects a mature digital presence with rich content targeting investors, customers, and partners. The technical infrastructure employs modern web technologies and responsive design, ensuring good performance and accessibility.

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

2 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.

    • 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. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Deutsche Telekom is positioned as a global telecommunications leader with a diversified business model focusing on integrated services and innovation. The company maintains transparency through detailed investor relations and corporate responsibility reporting. Its subsidiaries such as T-Systems and OTE expand its footprint in IT services and regional markets. The website's content and structure indicate a focus on corporate governance, sustainability, and digital transformation, appealing to a broad audience including investors and business partners. The use of advanced analytics and tag management tools like Tealium suggests a data-driven approach to customer engagement and marketing.

Security posture

The website enforces HTTPS and demonstrates GDPR compliance with clear privacy and cookie policies supported by a consent mechanism. The presence of ISO 27001 certification indicates adherence to recognized security standards. However, the lack of explicit security headers such as Content Security Policy and absence of a published security.txt file or incident response contact reduces transparency in vulnerability management. No vulnerabilities or exposed sensitive data were detected in the content. The security score is strong but could be enhanced by addressing these gaps to improve resilience and trust.

Recommendations

  1. Implement and publish comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve incident response transparency.
  3. Provide explicit incident response contact information on the website to enhance trust and readiness.
  4. Investigate and resolve the missing WHOIS registration data for the domain to ensure domain legitimacy and reduce risk.
  5. Continue to maintain and update privacy and cookie policies to align with evolving GDPR and data protection regulations.

Technical notes

Notes

The website uses a custom or proprietary CMS with modern front-end technologies including responsive images, web fonts, and JavaScript libraries such as Flickity for carousels. Tag management and analytics are handled via Tealium, indicating a mature digital marketing infrastructure. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed through meta tags and structured navigation. Opportunities exist to enhance security headers and improve incident response mechanisms. Hosting provider details are not explicitly identified from the content.
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.
