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

Open Telekom Cloud is a European-focused cloud service provider offering Infrastructure as a Service (IaaS) and managed cloud solutions primarily targeting business customers and enterprises. It operates under the Deutsche Telekom umbrella, emphasizing data sovereignty and compliance with European regulations such as GDPR. The website presents a professional and comprehensive digital presence with detailed product offerings, partner integrations, and community engagement. Technically, the site is built on modern PHP frameworks and the Neos CMS, delivering a responsive and accessible user experience. Security posture is strong, with HTTPS enforcement, security headers, and certifications like ISO 27001. Privacy compliance is well addressed with cookie consent mechanisms and detailed policies. The absence of WHOIS data is a minor anomaly but does not detract from the overall trustworthiness given the strong brand and professional presentation.

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 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

  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

The company holds a leading position in the European cloud market, leveraging Deutsche Telekom's infrastructure and reputation. Its business model focuses on providing cloud computing, storage, networking, and security services with an emphasis on compliance and data protection. The target customers are enterprises and regulated industries requiring sovereign cloud solutions. The ecosystem includes partner marketplaces, community platforms, and training services, indicating a mature and integrated offering. Growth is supported by certifications and a clear focus on European digital independence. The website content and navigation reflect a well-structured and customer-oriented approach.

Security posture

The website demonstrates a mature security posture with HTTPS, security headers, and compliance certifications. Privacy policies and cookie consent mechanisms align with GDPR requirements. However, no explicit vulnerability disclosure or security.txt file was found, which could improve transparency. Incident response contact information is not prominently displayed, suggesting an area for enhancement. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security measures are robust and appropriate for the business context.

Recommendations

  1. Publish a vulnerability disclosure policy or security.txt file to enhance transparency and trust.
  2. Make incident response contact information more visible to facilitate security communications.
  3. Regularly update and audit third-party scripts and tracking tools to minimize privacy risks.
  4. Enhance performance optimization to improve loading speed and user experience.
  5. Continue maintaining compliance certifications and update privacy policies as regulations evolve.

Notes

The website uses Neos CMS built on the Flow PHP framework, with extensive use of JavaScript and modern CSS for responsive design. Tag management and analytics are handled via Tealium. The site is hosted likely on Deutsche Telekom infrastructure, ensuring reliability and compliance. Performance is moderate with room for optimization. Accessibility and SEO are well implemented, supporting broad user reach. The technical stack is modern and well maintained, supporting the business's digital maturity and operational needs.
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.
