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

      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

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 targets buyers and sellers of real estate in the Czech Republic and abroad, operating a freemium business model with free basic listings and paid premium packages. Its competitive advantage lies in a large active listing base, integrated auction services, and value-added features like anonymous advertising and specialist sales assistance. Partnerships with other real estate platforms and a dedicated auction portal enhance its ecosystem. The company appears medium-sized with a stable foundation and a focus on digital marketing and user engagement. Growth indicators include a high volume of active listings and daily transactions. The partnership with Transparent Reality and the use of a professional web development firm indicate strategic alliances supporting operational excellence.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of Google reCAPTCHA to mitigate automated abuse. Cookie consent and privacy policies indicate GDPR awareness and compliance. However, the lack of a published security policy or incident response contacts limits transparency and preparedness communication. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of multiple third-party scripts requires ongoing vigilance to prevent supply chain risks. Overall, the security maturity is good but could be improved by formalizing security governance documentation and incident response channels.

Recommendations

  1. Publish a dedicated security policy page outlining security controls and commitments.
  2. Add clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance website accessibility features to improve compliance and user inclusivity.
  5. Regularly review and update third-party scripts and dependencies to mitigate supply chain vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack including Leaflet.js for interactive maps, FontAwesome for icons, Google Analytics and Tag Manager for analytics, and Google reCAPTCHA for bot protection. It loads resources asynchronously to improve performance and includes a cookie consent mechanism for privacy compliance. The site is mobile optimized with responsive design and clear navigation. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details were not discernible from the HTML content. Performance is moderate with room for optimization. The site uses multiple external domains for scripts and advertising, which requires careful management to maintain security and privacy standards.
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.
