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

STAVBY SPOL. S R.O. operates the website www.dverestavby.cz, providing door and flooring products along with installation services primarily in the Czech Republic. The company targets residential and commercial customers seeking quality doors, fittings, and flooring solutions. The website demonstrates a professional presence with detailed product offerings, virtual tours, and downloadable catalogs, positioning the company as a specialized regional provider with partnerships such as Sapeli. Technically, the website employs modern JavaScript libraries, Google Tag Manager for analytics, and Google reCAPTCHA for form security, indicating a moderate level of digital maturity. The site is mobile-optimized and SEO-friendly but lacks some advanced security headers and cookie consent mechanisms. Security posture is generally good with HTTPS enforced and no visible vulnerabilities, though improvements in security headers and privacy compliance are recommended. The absence of WHOIS data limits domain trust assessment but the website content and contact details suggest legitimacy. Overall, the site is safe, professional, and well-structured, suitable for its target market.

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

    • 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 in the real estate and construction sector, focusing on door and flooring sales and installation services. Its business model combines product retail with service delivery, including consultations and virtual tours to enhance customer experience. The presence of partner logos and detailed contact information supports credibility and market positioning. The website content is tailored to Czech customers, with localized addresses and language. The company appears to be small-sized with a focused regional presence. The partnership with Sapeli and other suppliers indicates a strong supplier ecosystem. The downloadable catalogs and blog content suggest active marketing and customer engagement strategies. No direct revenue or financial data is available, but the comprehensive service offering and digital presence indicate a stable business operation.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA to protect form submissions, which are positive security practices. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap that could expose the site to clickjacking, MIME sniffing, or other attacks. No sensitive data is exposed in the HTML, and no vulnerable libraries were detected. The site lacks a published security policy or incident response contacts, which could improve transparency and readiness. GDPR compliance is partially addressed via a privacy policy PDF, but no cookie consent mechanism is implemented, which is a compliance risk. Overall, the security posture is good but could be enhanced by implementing recommended headers, cookie consent, and incident response information.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and inform users about cookie usage.
  3. Publish a security policy and incident response contact information to improve transparency and preparedness.
  4. Consider creating a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Regularly review and update third-party libraries and scripts to avoid vulnerabilities and maintain security hygiene.

Technical notes

Notes

The website uses a modern tech stack including jQuery, Fancybox, Glide.js for UI components, Google Maps API for location display, and Google Tag Manager for analytics and tracking. The site is mobile-optimized with responsive design and good navigation clarity. Performance is moderate, with preloading of CSS and asynchronous loading of scripts to improve speed. The site lacks a detected CMS, suggesting a custom or static site architecture. Accessibility features are basic but present. SEO is supported by canonical tags, meta robots, and structured data (JSON-LD BreadcrumbList). The absence of some security headers and cookie consent mechanisms indicates areas for technical improvement. Hosting provider and domain age are unknown due to missing WHOIS data.
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.
