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

CyberDay.lu is a professionally maintained website representing an annual cybersecurity awareness event organized by the Fondation Restena in Luxembourg. The event is positioned as a key cybersecurity knowledge-sharing platform within the European Cyber Security Month and is partially funded by the European Union’s Digital Europe programme. The website targets cybersecurity professionals and stakeholders in Luxembourg and Europe, providing event schedules, speaker information, and registration details. The business model is event-driven, supported by public funding and institutional backing. Technically, the website is built on WordPress 6.8 with common web technologies such as jQuery, Bootstrap, and Font Awesome. The site demonstrates moderate performance and good mobile optimization but lacks advanced accessibility features. SEO optimization is basic, and no advanced analytics or tracking tools are detected, indicating a privacy-conscious approach or minimal user tracking. From a security perspective, the site uses HTTPS with good SSL configuration but lacks important security headers such as Content-Security-Policy and X-Frame-Options. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of privacy and cookie policies represents a compliance gap with GDPR requirements. Incident response and security policy information are not publicly available, which could be improved to enhance trust and transparency. Overall, CyberDay.lu presents a trustworthy and professional online presence for a niche cybersecurity event. The risk profile is low given the nature of the content and organizational backing. Strategic improvements in privacy compliance, security headers, and accessibility would strengthen the site’s security posture and regulatory adherence.

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

8 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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. 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

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

CyberDay.lu operates as a specialized event platform under the Fondation Restena, focusing on cybersecurity awareness in Luxembourg and Europe. Its competitive advantage lies in institutional support and EU funding, positioning it as a credible and authoritative event in the cybersecurity domain. The business model is centered on event organization and knowledge dissemination rather than commercial sales. The target audience includes cybersecurity professionals, government entities, and IT communities. The partnership with Restena Foundation and Cybersecurity Luxembourg enhances its ecosystem and outreach. Growth indicators include annual event continuity and EU program funding. The website content and structure support a professional image aligned with its mission.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible vulnerabilities or exposed sensitive data. However, the lack of security headers and absence of published security policies or incident response procedures indicate areas for improvement. GDPR compliance is partial due to missing privacy and cookie policies and no consent mechanism. The site does not appear to collect extensive user data or use tracking technologies, reducing privacy risks. Incident response readiness and security culture indicators are not publicly visible, suggesting potential gaps in transparency. Overall, the security posture is adequate for an informational event site but could benefit from enhanced security controls and compliance documentation.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add a cookie consent mechanism to inform users and obtain consent for any tracking.
  3. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the site against common web attacks.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Enhance website accessibility features to improve inclusivity and compliance with accessibility standards.

Technical notes

Notes

The website is built on a mature WordPress platform version 6.8, leveraging popular libraries such as jQuery, Bootstrap 3.3.6, Font Awesome 4.7.0, Slick Carousel, and Magnific Popup. The site uses a responsive design with good mobile optimization and moderate performance. SEO practices are basic with meta tags present but no advanced structured data or Open Graph tags detected. No analytics or tracking scripts were found, indicating minimal data collection. The hosting provider is not explicitly identified but the domain uses Restena name servers, suggesting hosting by or through Restena Foundation. The site lacks modern security headers and advanced accessibility features, representing opportunities for technical modernization and risk reduction.
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.
