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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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 direct sales and installation business model with a strong regional footprint in the Czech Republic, supported by 14 physical branches and a premium showroom. Their market position is that of an established mid-sized player emphasizing quality, design, and customer service. The target audience includes homeowners and developers seeking premium window and door solutions. Revenue streams likely derive from product sales, installation services, and consultation fees. The company leverages partnerships with suppliers of aluminum, plastic, and wooden window systems, including frameless designs. The website's content and structure support lead generation and customer engagement, with clear calls to action for showroom visits and inquiries. No evidence of parent or subsidiary companies was found. The company demonstrates consistent branding and trust signals such as experience and physical presence.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and Google reCAPTCHA protecting forms. Cookie consent is managed via CookieHub, indicating awareness of privacy regulations. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No vulnerability disclosure or incident response contacts are published, which limits transparency in security incident handling. No exposed sensitive data or vulnerable libraries were detected in the provided content. The site would benefit from publishing a privacy policy and terms of service to improve compliance and user trust. Overall, the security maturity is moderate with room for improvement in policy transparency and header implementation.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve GDPR compliance and user trust.
  2. Implement and configure security headers such as CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Add explicit incident response contact channels (e.g., security@ or abuse@ email addresses) to improve transparency and readiness.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and optimize performance.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap 5.3.3 for responsive design, Font Awesome for icons, Leaflet for interactive maps, and Google services for analytics and tag management. Cookie consent is handled by CookieHub, indicating compliance efforts. The site is mobile-optimized with good accessibility and SEO practices evident from meta tags and structured navigation. Performance is moderate, likely influenced by multiple external scripts and tracking pixels. No CMS was explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not disclosed. The site uses JavaScript-based autocomplete for search inputs, enhancing user experience. Technical debt appears low, but adding security headers and privacy documentation would modernize the security posture further.
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.
