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

The website represents the CYBERSECURITY Week Luxembourg 2025, a national campaign coordinated by the Luxembourg House of Cybersecurity. It aims to promote cybersecurity awareness and foster collaboration within the Luxembourg cybersecurity ecosystem through key events such as the Luxembourg GRC Conference and hack.lu. The campaign targets cybersecurity professionals and the wider community interested in cybersecurity topics. The website content is well-structured, professionally designed, and consistent with the organization's branding. Technically, the site uses modern web technologies including React, Bootstrap, and FontAwesome, with good mobile optimization and moderate performance. The site is served over HTTPS with no visible security vulnerabilities or exposed sensitive data. However, some security best practices like security headers and cookie consent mechanisms are missing or not visible in the provided content. From a security posture perspective, the site demonstrates a good baseline with HTTPS and no evident vulnerabilities. The presence of legal and data protection notices in PDF format indicates attention to compliance, though explicit security policies and incident response information are absent. The WHOIS data aligns well with the website's claims, showing consistent registration and no privacy protection, enhancing trustworthiness. Overall, the website is a credible, professional platform for cybersecurity awareness events in Luxembourg, with room for improvement in privacy compliance and security policy transparency.

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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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.

Technical appendix

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

Business context

Business profile

The Luxembourg House of Cybersecurity operates as an essential entity within the national cybersecurity ecosystem, coordinating awareness campaigns and events. Its market position is that of a national leader in cybersecurity awareness, leveraging partnerships with key organizations such as hack.lu. The business model focuses on event coordination and community engagement rather than direct commercial services. The target audience includes cybersecurity professionals, ecosystem members, and the general public interested in cybersecurity. The organization benefits from a strong partnership ecosystem and maintains a consistent brand identity. Growth indicators include recurring annual events and special editions like the Expo Osaka 2025 participation.

Security posture

The website exhibits a mature security posture with HTTPS enforced and no visible sensitive data exposure. However, the absence of security headers and a dedicated security policy page suggests opportunities for enhancement. No vulnerability disclosure or incident response contacts are provided, which could limit responsiveness to security issues. GDPR compliance is supported by linked data protection notices, but cookie consent mechanisms are missing. Overall, the security culture appears professional but could benefit from formalized policies and improved transparency.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and enhance user privacy transparency.
  2. Publish a dedicated security policy and incident response information page to improve security posture and user trust.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security at the server level.
  4. Enhance accessibility features to improve inclusivity and compliance with accessibility standards.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible vulnerability reporting.

Technical notes

Notes

The website is built using React with Bootstrap and FontAwesome for UI components and styling, indicating a modern and maintainable tech stack. Google Fonts are used for typography. The site loads JavaScript asynchronously and defers scripts for performance optimization. The site is mobile optimized with responsive design. No CMS or hosting provider information is explicitly detected. Performance is moderate, with potential for improvement in SEO and accessibility. No analytics or tracking scripts are detected, suggesting minimal user tracking. The site uses standard web fonts and icons, and the code structure is clean without visible errors.
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.
