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

KdeChciBydlet.cz is a Czech Republic-based real estate portal specializing in new apartments and family houses for sale, primarily focusing on developer projects. Operated by DALTEN media s.r.o., the site offers a catalog of residential projects, market news, and related services targeting individuals and families seeking new housing. The portal has an established market presence since 2007 and maintains partnerships with related real estate and construction service providers. Technically, the website uses legacy JavaScript libraries such as jQuery 1.11.3 and integrates common analytics and marketing tools including Google Analytics and Facebook SDK. While the site enforces HTTPS and implements cookie consent mechanisms, it lacks some modern security headers and uses outdated libraries that may pose security risks. Privacy and cookie policies are present and linked to a related domain operated by the same company, indicating reasonable GDPR compliance. Overall, the site is professionally designed with good content relevance and user experience, though technical modernization and enhanced security practices are recommended to improve resilience and trust.

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

9 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

      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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The portal operates as a niche real estate listing and advertising platform, monetizing primarily through advertising and partnerships with real estate service providers. Its target audience includes homebuyers interested in new developments in the Czech Republic. The company behind the site, DALTEN media s.r.o., is a medium-sized entity with a stable market position. The business model leverages curated developer project listings, market news, and advertising space. Partnerships with related domains such as realitymix.cz and utulne.cz enhance content offerings and market reach. The site’s longevity since 2007 and consistent branding support credibility. However, the absence of direct contact emails or phone numbers on the main page suggests a preference for contact via dedicated pages or forms, which may impact immediate user engagement.

Security posture

The website demonstrates a moderate security posture with mandatory HTTPS enabled and cookie consent mechanisms in place. However, the use of outdated JavaScript libraries like jQuery 1.11.3 introduces potential vulnerabilities. The absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No exposed sensitive data or obvious vulnerabilities were detected in the HTML content. Incident response and security policy documentation are not publicly available, indicating room for improvement in transparency and preparedness. Overall, the security maturity is adequate for a content-driven portal but requires updates and enhancements to align with best practices and regulatory expectations.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Enhance accessibility and mobile optimization to improve user experience across devices.
  5. Regularly audit and update privacy and cookie policies to maintain GDPR compliance and user trust.

Technical notes

Notes

The website is built on a custom or unknown CMS platform using legacy JavaScript libraries such as jQuery 1.11.3 and jQuery Migrate 1.2.1, alongside LightGallery for image display. It integrates Google Analytics, Google Tag Manager, and Facebook SDK for analytics and marketing. The site uses multiple CSS stylesheets and favicons for branding consistency. Hosting details are not explicitly disclosed but the domain registrar is REG-WEBGLOBE. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with meta tags and Open Graph tags present but no JSON-LD structured data detected. The site uses asynchronous loading for analytics scripts and has a cookie consent banner with granular consent options. Technical debt is indicated by outdated libraries and missing security headers, suggesting modernization opportunities to improve security and performance.
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.
