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

The VELUX Group website represents a well-established global manufacturer specializing in roof windows, sun tunnels, blinds, and shutters designed to improve indoor environments with natural light and fresh air. The company targets homeowners, builders, architects, and commercial building professionals, emphasizing sustainability and healthy building practices. The website is professionally designed with clear navigation, mobile optimization, and comprehensive content that supports the brand's market position as a leader in daylight solutions. Technically, the site leverages a mature technology stack including ASP.NET CMS, jQuery, Font Awesome, and integrates multiple marketing and analytics tools such as Google Tag Manager, Cookiebot, Hotjar, and Visual Website Optimizer. The presence of cookie consent mechanisms and privacy policies indicates a strong commitment to privacy compliance, including GDPR adherence. Performance is moderate with good mobile responsiveness and SEO practices. Security posture is solid with HTTPS enforced and use of CSRF tokens, though explicit security headers are not clearly visible in the HTML source. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data is missing or unavailable, which reduces domain transparency and trust slightly, but the overall website and business indicators suggest legitimacy. Overall, the website is secure, privacy-conscious, and professionally maintained, supporting a reputable global manufacturing business. Strategic improvements include enhancing security headers and verifying domain registration details for improved trust.

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 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';…

  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

VELUX Group operates in the manufacturing sector with a focus on building products that enhance indoor environments through daylight and fresh air. The company has a strong global presence with localized websites and commercial subdomains, indicating a broad market reach. Their business model combines product manufacturing with digital tools and sustainability initiatives, targeting both residential and commercial markets. The use of multiple marketing and analytics platforms suggests a data-driven approach to customer engagement and growth. Partnerships with local blind shops and commercial distributors further strengthen their market ecosystem. The company’s long history and consistent branding position it as a trusted leader in its niche.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, CSRF protection, and cookie consent mechanisms. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options in the HTML source is a gap that could be addressed to enhance protection against common web attacks. The extensive use of third-party scripts and marketing tools necessitates ongoing vulnerability management. No incident response or security policy pages were found, which could be improved to demonstrate security governance. The missing WHOIS data reduces transparency but may be due to privacy protection services. Overall, the security posture is good but could benefit from additional header implementations and published security policies.

Recommendations

  1. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a dedicated security policy and incident response information to improve transparency and trust.
  3. Regularly audit and update third-party scripts and marketing tools to mitigate potential vulnerabilities.
  4. Verify and publish domain registration details or provide a WHOIS privacy justification to enhance domain trustworthiness.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on an ASP.NET CMS platform with a front-end leveraging jQuery and Font Awesome for UI components. It integrates multiple third-party marketing and analytics services including Google Tag Manager, Cookiebot, Hotjar, and Visual Website Optimizer, indicating a sophisticated digital marketing infrastructure. The site is mobile optimized and uses lazy loading for images, though some images showed loading errors in the snapshot. Performance is moderate, with room for improvement in loading speed and accessibility. The presence of structured navigation and meta tags supports SEO efforts. Technical debt appears low, but continuous monitoring of third-party dependencies is recommended to maintain security and performance.
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.
