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

The company operates a specialized e-commerce platform focused on custom window and door products, leveraging a configurator tool to enable customers to tailor products to their needs. Their market position is strong within the Netherlands, supported by over 150,000 window frames sold and a dedicated business customer program. Revenue streams likely include direct sales through the webshop and project support services for larger orders. The partnership ecosystem includes technology providers like Storyblok and Cookiebot. Growth indicators include a comprehensive product catalog and active customer reviews. Strategic observations suggest opportunities to enhance trust by publishing detailed privacy and security policies and expanding incident response transparency.

Security posture

The website employs HTTPS with strong SSL configuration and implements key security headers such as Content-Security-Policy and Strict-Transport-Security, indicating a solid security foundation. Cookie consent is actively managed, supporting GDPR compliance efforts. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms represents gaps in security maturity. No exposed sensitive data or vulnerable libraries were detected. The current posture is good but could be improved by formalizing security governance documentation and communication channels.

Recommendations

  1. Publish a comprehensive privacy policy page detailing GDPR compliance and data handling practices.
  2. Add terms of service and security policy documents accessible from the website footer.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Provide clear incident response contact information, including dedicated security or abuse email addresses.
  5. Regularly review and update security headers and cookie consent mechanisms to maintain compliance and trust.

Technical notes

Notes

The website is built on a modern React/Next.js framework with Storyblok as the CMS, ensuring a scalable and maintainable infrastructure. Performance is optimized with preloading of fonts and images, and the site is mobile responsive with good accessibility features. Analytics and marketing tools are integrated via Google Tag Manager and Mopinion, with cookie consent managed by Cookiebot. No critical technical debt or vulnerabilities were identified. Hosting details are not explicitly disclosed but the use of CDN and external services suggests a robust hosting environment. Opportunities exist to enhance technical documentation and transparency around security and privacy.
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.
