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

LuxCSD S.A. operates as a licensed central securities depository under the Central Securities Depositories Regulation (CSDR), providing issuer and investor services primarily in fixed income and equity securities. The company offers custody, settlement, and asset servicing solutions, targeting custodian banks, issuers, and distributors. Affiliated with the Deutsche Börse Group, LuxCSD holds a reputable market position with STEP eligibility and multi-jurisdictional issuer services. The website reflects a professional and well-structured digital presence with good content quality and navigation. Technically, the website employs modern JavaScript libraries and analytics tools such as Matomo, alongside a cookie consent management system ensuring GDPR compliance. The infrastructure appears stable and moderately optimized for performance and mobile use, though explicit security headers and detailed hosting information are not evident from the data provided. From a security perspective, the site uses HTTPS and session cookies for secure user sessions, with a cookie consent banner indicating privacy awareness. However, the absence of visible security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and security maturity. The WHOIS data is notably missing or inaccessible, which raises concerns about domain registration legitimacy despite the professional business content. Overall, LuxCSD presents a credible and professional financial services platform with solid compliance and user experience. Strategic recommendations include enhancing security header implementation, publishing explicit security and incident response policies, and verifying domain registration details to strengthen trust and reduce risk.

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 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 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, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

LuxCSD is positioned as a specialized financial market infrastructure entity focusing on securities depository and settlement services. Its competitive advantage lies in regulatory licensing under CSDR, STEP eligibility, and affiliation with Deutsche Börse Group, enabling it to serve a niche market of issuers and custodians across multiple jurisdictions. The business model revolves around providing issuer and investor CSD services, asset servicing, and connectivity solutions, generating revenue through service fees to financial institutions. The website's partner ecosystem includes Clearstream, BCL, and the ECB, indicating strong institutional relationships. Growth indicators include recent service launches under Guernsey law and sustainability initiatives. The company targets institutional clients requiring secure and efficient securities settlement and custody solutions.

Security posture

The current security posture of the LuxCSD website is moderate. HTTPS is enforced, and session management cookies are used appropriately. The presence of a cookie consent mechanism aligns with privacy regulations. However, the lack of visible security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces the overall security robustness. No explicit security policies, incident response contacts, or vulnerability disclosure programs are published, which limits transparency and preparedness for security incidents. The missing WHOIS data for the domain is a concern, potentially indicating registration issues or privacy protection that is not justified for a regulated financial entity. No vulnerabilities or exposed sensitive data were detected in the provided content. Enhancing security headers, publishing security policies, and establishing clear incident response channels would improve the security maturity significantly.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response information on the website.
  3. Establish and publicize a vulnerability disclosure program or security.txt file.
  4. Verify and update WHOIS domain registration information to ensure transparency and trust.
  5. Enhance data protection officer contact visibility and privacy compliance documentation.

Technical notes

Notes

The website uses a modern JavaScript-based front end with jQuery and custom scripts. It integrates Matomo analytics for visitor tracking and Cookie-Script for consent management, indicating a focus on privacy compliance. The site is hosted likely on infrastructure related to Deutsche Börse Group, with no explicit CMS detected. Performance is moderate with responsive design and accessibility features implemented. However, the absence of detailed security headers and explicit hosting information suggests potential technical debt or areas for modernization. The search form uses AJAX autocomplete, enhancing user experience. Overall, the technical implementation supports the business needs but could benefit from enhanced security and performance optimizations.
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.
