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

DE-CIX Management GmbH operates a globally recognized network of Internet Exchange Points (IXPs), providing premium interconnection services across Europe, the Middle East, Africa, Asia, and the Americas. The company is a leader in the telecommunications sector, offering a broad portfolio of services including peering, private interconnects, cloud connectivity, and security solutions. Their website reflects a mature business with a strong market position and a focus on network operators, enterprises, and cloud providers as their primary audience. Technically, the website is built on the Neos CMS platform using the Flow PHP framework, integrating modern technologies such as Google Tag Manager and Sentry for analytics and error tracking. The site is well-optimized for performance, mobile responsiveness, and accessibility, with comprehensive SEO metadata and structured data enhancing discoverability. From a security perspective, the website enforces HTTPS and employs cookie consent mechanisms compliant with GDPR. While explicit security headers are not fully visible in the HTML, the overall posture is strong with no exposed sensitive data or vulnerabilities detected. However, the absence of a published security policy or vulnerability disclosure program suggests areas for improvement. Overall, the website demonstrates high professionalism, trustworthiness, and compliance with privacy regulations. The lack of WHOIS data is likely due to privacy protection and does not detract from the legitimacy of the business. Strategic recommendations include enhancing security header implementation, publishing formal security and incident response policies, and establishing a vulnerability disclosure framework.

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

DE-CIX holds a leading position in the global Internet Exchange market, leveraging a broad geographic footprint and a diverse service portfolio. Their business model centers on providing neutral, carrier- and data center-independent interconnection services that enable efficient network peering and cloud connectivity. Revenue streams likely include service subscriptions, premium peering, and infrastructure offerings. The company targets network operators, enterprises, cloud providers, and data centers, supported by a strong partner ecosystem evident from multiple linked partner domains. The website's content and branding reinforce DE-CIX's reputation as a trusted and innovative player in telecommunications interconnection.

Security posture

The website exhibits a mature security posture with enforced HTTPS, GDPR-compliant cookie consent, and use of modern monitoring tools like Sentry. No critical vulnerabilities or exposed sensitive information were found in the HTML content. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not clearly present or documented, which could be enhanced. The absence of a public security policy, incident response contact, or vulnerability disclosure program limits transparency and may impact trust among security-conscious stakeholders. Overall, the security maturity is good but could benefit from formalized policies and improved header configurations.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data protection officer contact details and data retention policies.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize tracking footprint.

Notes

The website is built on a modern and robust technical stack featuring Neos CMS and the Flow PHP framework, supported by advanced JavaScript libraries for analytics and interactive content (AmCharts, Blaze Slider). Performance is optimized with asynchronous script loading and CDN usage (Cloudflare Insights). The site is mobile-optimized with responsive design and accessibility considerations. SEO is well addressed through meta tags, Open Graph, and JSON-LD structured data. No technical debt or deprecated technologies were detected. Opportunities exist to further enhance security headers and formalize technical documentation for security and privacy.
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.
