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 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. 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

Deutsche Börse AG's website reveals a mature business model centered on financial market infrastructure, serving a diverse audience including institutional investors, asset managers, and media. The company leverages a broad ecosystem of subsidiaries and partners to deliver integrated services such as trading platforms (Xetra, Eurex), clearinghouses (Clearstream), and market data providers (ISS STOXX). The presence of sustainability and corporate governance content indicates alignment with regulatory and investor expectations. The career portal and media sections support talent acquisition and public relations efforts, respectively. The company’s long domain age and consistent branding reinforce its established market presence.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism, reflecting compliance with basic security and privacy standards. Use of Matomo analytics suggests a privacy-aware approach to user tracking. However, the absence of DNSSEC and security headers like Content-Security-Policy and X-Frame-Options indicates potential areas for enhancement. No explicit security policies or incident response contacts were found, which could improve transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security posture is good but could be strengthened with additional best practices and disclosures.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy clearly linked on the website to improve GDPR compliance transparency.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  4. Provide explicit security policy and incident response information, including dedicated contact channels for security issues.
  5. Consider publishing a security.txt file or vulnerability disclosure policy to encourage responsible reporting.

Technical notes

Notes

The website uses a modern and clean technical stack with HTML5, CSS3, and JavaScript, including asynchronous loading of scripts and modular JavaScript files. The use of easyXDM for iframe communication and Matomo for analytics indicates a focus on modularity and privacy. Hosting appears stable and performant, likely managed internally or via Deutsche Telekom AG. The site is mobile-optimized and accessible, with good SEO metadata and Open Graph tags. Performance is moderate, with potential for optimization in script loading and image compression. No CMS was explicitly detected, suggesting a custom or proprietary solution.
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.
