DAV, a.s. is a Czech construction and demolition company with over 30 years of experience, providing comprehensive services including demolition, construction of new buildings, reconstruction, and earthworks. The company employs approximately 100 staff and operates with its own machinery and technical equipment, positioning itself as a reliable general contractor in the Czech market. The website reflects a professional and consistent brand image with clear contact information and references to certifications, enhancing trustworthiness. Technically, the website uses a modern but standard tech stack including jQuery, jQuery UI, Slick Carousel, and Lightbox. It is mobile optimized and provides a good user experience with clear navigation and relevant content. SEO and accessibility are adequately addressed, though some improvements could be made in accessibility features and performance optimization. From a security perspective, the site uses HTTPS and implements cookie consent mechanisms compliant with GDPR. However, security headers are not explicitly detected in the HTML content, and there is no visible incident response or vulnerability disclosure information. The site does not expose sensitive data and uses common analytics and marketing tools responsibly. Overall, the website is secure, compliant, and professionally maintained, supporting the company's credibility. Recommendations include enhancing security headers, publishing incident response contacts, and considering a security.txt file to improve transparency and security posture.

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

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.

Business context

Business profile

DAV, a.s. holds a stable position in the Czech construction and demolition sector, leveraging over three decades of experience and a workforce of about 100 employees. Its business model focuses on providing end-to-end construction services, including demolition, new builds, and renovations, often acting as a general contractor. The company emphasizes quality and certifications (ISO 9001, 14001, 45001), which serve as competitive advantages. The target customers are likely commercial and residential developers, industrial clients, and public sector entities. The company maintains active social media profiles and a professional website showcasing references, which supports marketing and client acquisition efforts. There is no indication of parent or subsidiary companies, suggesting an independent medium-sized enterprise.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and cookie consent is implemented in compliance with GDPR. The absence of visible security headers such as Content Security Policy or HSTS is a minor gap. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of explicit incident response contact information and vulnerability disclosure mechanisms limits transparency and readiness for security incidents. The use of third-party analytics and marketing scripts is managed with user consent, reducing privacy risks. Overall, the security posture is adequate for the business type but could be improved with additional security best practices and incident response disclosures.

Recommendations

  1. Implement security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish explicit incident response contact information (e.g., security@ or abuse@ email) to improve transparency and readiness.
  3. Consider creating and hosting a security.txt file to facilitate vulnerability reporting and improve security communication.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website uses a traditional but stable technology stack centered on jQuery and jQuery UI, supplemented by Slick Carousel for sliders and Lightbox for image display. The HTML and CSS are valid and well-structured, supporting good SEO and mobile responsiveness. Performance is moderate, with potential for optimization in script loading and caching. No CMS is explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not disclosed in the HTML content. The site includes meta tags for viewport and description, aiding SEO. Accessibility is basic but could be improved with ARIA roles and better keyboard navigation support. Overall, the technical implementation is solid but could benefit from modernization and enhanced security practices.
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.
