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

3 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 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
    • 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 operates as a critical infrastructure provider in the telecommunications sector, focusing on Internet Exchange Points (IXPs) that enable efficient peering and interconnection among networks globally. Its business model revolves around providing neutral, carrier- and data center-independent interconnection services, facilitating network optimization and cloud connectivity for enterprises and service providers. The company leverages partnerships with regional IXPs and data centers to expand its footprint. Revenue streams likely include service subscriptions, interconnection fees, and value-added services such as cloud routing and security features. The target customer segments include large enterprises, ISPs, cloud providers, and network operators. The presence of a partner ecosystem and extensive location coverage indicates a growth-oriented strategy with strong competitive advantages in scale and neutrality.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, modern security headers, and a comprehensive cookie consent mechanism aligned with GDPR requirements. The use of Sentry for error monitoring indicates proactive incident detection capabilities. However, the absence of publicly available security policies, incident response procedures, and vulnerability disclosure channels suggests areas for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the website content. The security culture appears professional but could benefit from enhanced communication of security governance and contact points for security incidents.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide contact details for a Data Protection Officer or security team to enhance compliance and communication.
  4. Add clearly labeled company phone numbers and direct contact emails to improve accessibility for business and security inquiries.
  5. Regularly audit and update third-party scripts and tracking tools to mitigate potential security risks.

Technical notes

Notes

The website is built on a modern technology stack featuring the Neos CMS and Flow PHP framework, supported by JavaScript for dynamic content and Google Tag Manager for analytics. The site is well-optimized for performance and mobile devices, with good accessibility and SEO practices evident from meta tags and structured data. The use of Sentry for error tracking enhances operational reliability. No technical debt or outdated technologies were observed. Opportunities exist to further modernize by integrating explicit security and compliance automation tools and enhancing direct integration with partner services.
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.
