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

KÜS DATA GmbH is a German IT service provider specializing in secure data center operations and managed IT services. The company operates one of the most modern and secure data centers in Germany, offering colocation, managed servers, cloud services, backup solutions, and hosting. Their market position is strengthened by certifications such as ISO 27001 and DIN EN 50600, emphasizing their commitment to data security and compliance. The website targets business clients requiring high-security IT infrastructure and data protection services. Technically, the website is built on WordPress with Elementor and Yoast SEO plugins, indicating a modern and maintainable digital infrastructure. The site is mobile-optimized, uses HTTPS, and implements cookie consent mechanisms, reflecting a mature digital presence. Performance is moderate with good SEO and accessibility basics. From a security perspective, the company demonstrates strong practices including certified data center operations, HTTPS enforcement, and cookie consent compliance. However, explicit security headers could be improved, and no public incident response or vulnerability disclosure policies were found. No vulnerabilities or suspicious indicators were detected in the website content. Overall, KÜS DATA GmbH presents a trustworthy and professional online presence with a solid security posture and compliance awareness. Strategic improvements in security header implementation and incident response transparency would further enhance their security maturity.

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

5 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

  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
    • 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';…

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.

Business context

Business profile

KÜS DATA GmbH operates within the technology sector, focusing on secure data center services and managed IT solutions. Their business model is B2B, targeting enterprises and organizations needing reliable and secure IT infrastructure. The company benefits from a strong group affiliation with several sister companies under the KÜS brand, enhancing their ecosystem and service offerings. Revenue streams likely include colocation rentals, managed services subscriptions, and hosting fees. The presence of certifications and a professional website indicates a stable and growth-oriented business. Partnerships and sister sites suggest a collaborative approach to market expansion and service diversification.

Security posture

The security posture of KÜS DATA GmbH is robust, supported by internationally recognized certifications (ISO 27001, DIN EN 50600) and a secure data center infrastructure. The website enforces HTTPS and uses cookie consent tools, indicating compliance with GDPR and data protection laws. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a public incident response contact or security.txt file limits transparency in vulnerability handling. Security headers could be more explicitly configured. Overall, the company shows a mature security culture appropriate for its industry and clientele.

Recommendations

  1. Implement and verify comprehensive HTTP security headers such as X-Frame-Options and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish an incident response policy or dedicated security contact page to improve transparency and readiness for security events.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure and improve trust with security researchers.
  4. Enhance website accessibility features to comply with recognized standards and improve user experience for all visitors.
  5. Maintain regular security audits and update third-party plugins and libraries to mitigate potential vulnerabilities.

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.
