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.

Priority findings

6 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. Security headers

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

VELUX maintains a strong competitive advantage through its global brand recognition, extensive product range, and professional service network. The business model combines manufacturing with direct retail and professional support, including installer and dealer networks. The website reflects a strategic focus on customer education, product modernization, and sustainability. Partnerships with specialized domains such as veluxeshop.cz and podklady.velux.cz enhance the ecosystem, supporting both end consumers and professionals. Growth indicators include active marketing campaigns, seasonal promotions, and content marketing via a magazine section. The company demonstrates a commitment to digital transformation and customer-centric services, positioning itself well in the home improvement and construction sectors.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and cookie consent compliance aligned with GDPR. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a public vulnerability disclosure policy or security.txt file and lack of explicit incident response contact details represent gaps in transparency and readiness. The use of third-party scripts and analytics is managed with consent mechanisms, reducing privacy risks. Overall, the security measures are robust but could be enhanced by formalizing vulnerability reporting and incident response processes to build greater trust and compliance assurance.

Recommendations

  1. Publish a security.txt file or dedicated vulnerability disclosure page to facilitate responsible reporting.
  2. Add explicit incident response contact information, such as a security or abuse email address.
  3. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  4. Enhance transparency by publishing security certifications or compliance attestations if available.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website is built on a modern technology stack featuring Vue.js for frontend interactivity and Sitecore CMS for content management. It integrates Algolia for search functionality and Google Tag Manager for analytics and marketing tags. Performance is optimized with preloading fonts and images, asynchronous script loading, and responsive design for mobile devices. Accessibility considerations are evident, with semantic HTML and ARIA attributes. SEO is supported by comprehensive meta tags, Open Graph data, and structured JSON-LD schema. The technical infrastructure supports a fast, user-friendly experience with scalable content delivery. Opportunities exist to further enhance technical robustness by implementing advanced security headers and continuous performance monitoring.
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.
