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

Open Telekom Cloud is a cloud service platform operated by Deutsche Telekom AG, offering Infrastructure as a Service (IaaS) with a strong emphasis on European data sovereignty, security, and compliance with GDPR. The platform targets business customers, enterprises, and public sector organizations seeking secure and sovereign cloud solutions hosted in German data centers. The website presents a professional and comprehensive digital presence, highlighting key services such as computing, storage, networking, and managed services, supported by certifications like ISO 27001 and GDPR compliance. Technically, the website is built on the Neos CMS platform using the Flow PHP framework and integrates modern web technologies including JavaScript and OpenStack for cloud infrastructure. The site is well-optimized for performance, mobile responsiveness, and accessibility, with strong SEO practices and detailed metadata. Security posture is robust, featuring HTTPS, security headers, consent management, and published security guidelines, although it lacks a published security.txt and explicit incident response contacts. Overall, the security posture is strong with no visible vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with clear policies and consent mechanisms. The WHOIS data is unavailable or protected, which slightly reduces trust but is likely justified given the enterprise nature. The website is trustworthy, professional, and well-positioned in the European cloud market.

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

Business profile

Open Telekom Cloud is positioned as a leading European cloud provider focusing on sovereignty and security, leveraging Deutsche Telekom's brand and infrastructure. Its business model revolves around providing cloud infrastructure services to enterprises and public sector clients, emphasizing compliance with European regulations like GDPR. The company maintains a strong partner ecosystem including marketplaces, community platforms, and training services, enhancing customer engagement and support. The presence of certifications and detailed security policies strengthens its competitive advantage. The platform's focus on OpenStack technology and managed services indicates a commitment to open standards and customer-centric solutions. Growth indicators include active community engagement, regular webinars, and a comprehensive business navigator tool to assist customers in cloud adoption.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and GDPR-compliant cookie consent mechanisms. The publication of security guidelines for penetration testing reflects transparency and a proactive security culture. However, the absence of a security.txt file and explicit incident response contact details are areas for improvement. No vulnerabilities or sensitive data exposures were detected in the content. The use of reputable hosting and technology providers further enhances security. Overall, the security measures align well with industry best practices for cloud service providers, supporting trust and compliance requirements.

Recommendations

  1. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  2. Provide explicit incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  4. Enhance visibility of data protection officer contact details to strengthen GDPR compliance.
  5. Continue to maintain and communicate certifications and compliance achievements to build customer trust.

The website is built on a modern technology stack including Neos CMS and the Flow PHP framework, supported by OpenStack cloud infrastructure. It employs JavaScript for dynamic content and integrates Tealium for tag management and analytics. The site is well-structured with valid HTML and CSS, optimized for fast loading and mobile responsiveness. Accessibility features are implemented to a good standard, and SEO practices are robust with comprehensive metadata and structured data (JSON-LD).

Technical risks are minimal, with opportunities to improve include adding a security.txt and enhancing incident response visibility.
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.
