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

Koupelny JaS is a Czech retail and wholesale company specializing in ceramic tiles, bathroom equipment, and accessories. Established in 1992, it operates multiple physical stores across the Czech Republic and offers services including delivery, 3D bathroom design, and professional installation. The website is well-structured, providing detailed product catalogs and clear contact information, supporting its market position as a reputable regional player in the bathroom retail sector. Technically, the site uses modern JavaScript libraries and tracking tools such as Google Analytics 4 and Sklik.cz, with good mobile optimization and user experience. Security posture is moderate with HTTPS usage and cookie consent mechanisms, but lacks visible advanced security headers. The absence of WHOIS data reduces domain trustworthiness, though the website content and contact details appear legitimate. Overall, the site presents a professional and trustworthy front for its business operations.

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

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

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 targets both retail customers and business clients in the Czech Republic, leveraging a hybrid business model of wholesale and retail sales. Its competitive advantage lies in its extensive physical presence, comprehensive product range, and value-added services like graphic design and installation. The partnership with external virtual bathroom platforms enhances customer engagement. The business shows signs of maturity with consistent branding and a clear market niche in bathroom products. Revenue streams likely include product sales, design services, and installation. The company maintains a strong ecosystem of suppliers and partners, as evidenced by the supplier logos and linked domains. Strategic observations suggest focusing on digital marketing and expanding online presence could further strengthen market position.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is implemented, and cookie consent mechanisms indicate GDPR awareness. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site uses third-party tracking scripts which should be regularly audited for security. Incident response and security policy information are not publicly available, indicating potential gaps in transparency and readiness. Overall, the security posture is adequate for a retail website but could benefit from enhanced security controls and published policies.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response plan to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts to avoid vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Verify and update WHOIS registration details to improve domain trustworthiness and legitimacy.

Technical notes

Notes

The website uses a modern front-end stack with JavaScript and CSS, leveraging Swiper.js for interactive sliders and Google Tag Manager for analytics and marketing. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate, with potential for optimization in loading times and resource management. The CMS is not explicitly identified, suggesting a custom or proprietary solution. SEO is well addressed with meta tags and structured navigation. Technical risks include the absence of visible security headers and incomplete WHOIS data, which could impact trust and security posture. Opportunities exist to modernize infrastructure, improve security configurations, and enhance accessibility compliance.
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.
