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

S - STAV s.r.o. is a Czech Republic-based construction company specializing in building family and apartment houses, renovations, and machine-applied plasters and coatings. The company positions itself as a reliable partner with long-term experience and trusted suppliers, targeting individuals and businesses seeking quality construction and renovation services. The website is professionally designed, mobile-optimized, and provides clear navigation and relevant content in Czech language. Technical infrastructure includes modern libraries such as Bootstrap, jQuery, and Swiper.js, with HTTPS enforced and cookie consent implemented, indicating a moderate level of digital maturity. However, the absence of WHOIS data limits the ability to fully verify domain legitimacy and company registration details. Security posture is adequate with HTTPS but lacks advanced security headers and incident response information. Privacy compliance is supported by visible privacy and cookie policies aligned with GDPR requirements. Overall, the website presents a trustworthy and professional image but would benefit from enhanced security practices and transparency in domain registration.

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

      Third-party services without privacy policy

      Detected services: YouTube, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

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 residential building and renovation services. Its business model revolves around direct service provision with a focus on quality and customer satisfaction, supported by partnerships with well-known suppliers. The presence of customer testimonials and partner logos suggests a stable local market position. The website targets Czech-speaking customers, primarily in the Czech Republic, and appears to be a small-sized enterprise. No information about founding year or parent/subsidiary companies is available. The company leverages digital presence mainly for marketing and customer engagement without extensive tracking or advertising. The lack of social media links and analytics tools indicates a conservative digital marketing approach.

Security posture

The website enforces HTTPS, which is mandatory for secure communications. However, it lacks important security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options, which could improve protection against common web attacks. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The cookie consent mechanism is implemented, supporting privacy compliance. There is no evidence of a vulnerability disclosure policy or incident response contact, which are recommended for improving security maturity. The absence of WHOIS data is a concern for domain legitimacy verification and may indicate privacy protection or registration issues. Overall, the security posture is moderate but could be improved with additional security controls and transparency.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against web vulnerabilities.
  2. Publish a vulnerability disclosure policy and provide clear incident response contact information to improve security transparency and readiness.
  3. Regularly audit and update third-party libraries to mitigate risks from vulnerable dependencies.
  4. Enhance WHOIS domain registration transparency to improve trust and legitimacy perception.
  5. Consider integrating analytics and social media channels to improve marketing reach while maintaining privacy compliance.

Technical notes

Notes

The website uses a modern front-end technology stack including Bootstrap 4.2.1 for responsive design, jQuery for DOM manipulation, Swiper.js for carousels, and YouTube iframe API for embedded videos. Google Fonts are used for typography. CookieConsent2 is implemented for cookie management. The site loads external resources from reputable CDNs and partner domains. Performance is moderate with no obvious blocking scripts or errors. Mobile optimization is good, and SEO meta tags including Open Graph tags are properly configured. No CMS or hosting provider information is discernible from the HTML content. The site lacks advanced accessibility features but provides basic compliance. Overall, the technical implementation is solid with room for improvement in security and analytics integration.
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.
