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

7 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
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      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 company operates in the retail and manufacturing sectors, focusing on plastic windows and doors. Its business model combines direct online sales with a configurator for custom products, appealing to a broad audience including professionals and end consumers. The firm benefits from a strong parent company brand, TT HOLDING, and maintains partnerships with CMS and development providers. Customer testimonials and certifications like Heureka enhance credibility. The company shows growth potential with a multi-country presence and a focus on customer service and technical support.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of Google reCAPTCHA to protect forms, and a comprehensive cookie consent mechanism aligned with GDPR. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of explicit security headers such as CSP and HSTS is a minor gap. There is no public security policy or incident response information, which could be improved to enhance transparency and readiness. Overall, the security measures are appropriate for the business type and size.

Recommendations

  1. Implement and explicitly configure security headers like Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.
  5. Enhance mobile performance optimizations and accessibility features to maintain excellent user experience.

Technical notes

Notes

The website is built on OMNIX CMS and uses a combination of jQuery and modern JavaScript modules. It integrates multiple analytics and marketing tools including Google Analytics, Microsoft Clarity, and Google Tag Manager. The site loads asynchronously many scripts to optimize performance. The design is responsive and accessible with clear navigation and structured content. There is room for improvement in explicit security header implementation and possibly in hosting transparency. Overall, the technical infrastructure supports a robust and scalable e-commerce platform.
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.
