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.

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

Daibau.cz operates in the Real Estate sector, focusing on construction and renovation services. Its business model revolves around facilitating connections between customers and verified local service providers, leveraging customer reviews and project inquiries to drive engagement. The platform has a strong presence in the Czech market and extends its reach through sister sites in multiple European countries. Key competitive advantages include a large verified provider base, extensive customer ratings, and integrated pricing tools. The company appears medium-sized with a professional brand identity and consistent content quality. Partnerships with regional sister sites enhance its market coverage and service localization.

Security posture

The website maintains a good security posture with mandatory HTTPS, cookie consent management, and CSRF protection cookies. However, it lacks explicit HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended to mitigate common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The use of third-party tracking scripts like Google Analytics and Facebook Pixel is managed with user consent. Incident response and security policy documentation are not publicly available, indicating an area for improvement in transparency and readiness.

Recommendations

  1. Implement Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options HTTP headers to enhance security.
  2. Publish clear security policy and incident response procedures accessible to users.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Consider publishing vulnerability disclosure and data protection officer contact information.

Technical notes

Notes

The website uses a modern tech stack including jQuery, lazy loading for images, Google Fonts, and analytics/tracking tools such as Google Tag Manager and Facebook Pixel. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate, with room for improvement in loading speed and accessibility compliance. No CMS was explicitly detected, suggesting a custom or proprietary platform. SEO is well addressed with proper meta tags and Open Graph data. Hosting provider details are not discernible from the content. Overall, the technical implementation supports a professional and functional user experience.
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.
