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

    • 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

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 business model centers on providing a centralized platform for real estate listings and agency promotion, generating revenue likely through advertising and premium listings. The presence of regional subdomains and partnerships with numerous agencies indicates a broad market reach and strong ecosystem integration. The company leverages multiple marketing and analytics tools to optimize user engagement and advertising effectiveness. The platform's scale and content depth suggest a mature operation with significant market penetration in the Czech real estate industry.

Security posture

The website enforces HTTPS and employs common tracking and marketing scripts loaded asynchronously to minimize performance impact. However, explicit security headers are not detected, and no public security policy or incident response contacts are found, indicating room for improvement in security transparency and hardening. The cookie consent mechanism is present, supporting basic privacy compliance. No vulnerabilities or exposed sensitive data were identified in the analyzed content. Overall, the security posture is moderate but could benefit from enhanced headers and formalized security disclosures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages to improve legal compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen protection against common web attacks.
  3. Publish a security.txt file and provide clear incident response contact information to facilitate vulnerability reporting and improve security posture.
  4. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize unnecessary data collection.

Technical notes

Notes

The website uses a modern JavaScript framework (Vue.js) combined with Symfony backend components, indicating a contemporary and maintainable tech stack. It employs module preload and import maps for efficient resource loading. The site integrates multiple analytics and marketing tools including Google Tag Manager, Facebook SDK, and Gemius, reflecting a data-driven approach. Performance is moderate with asynchronous script loading and preconnect hints. Mobile optimization is good, and SEO meta tags are well implemented. No CMS is explicitly detected, suggesting a custom or proprietary solution. Hosting provider details are not available from the provided 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.
