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. 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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      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

      What to do: Implement a Content-Security-Policy appropriate for your application

      • 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

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 operates in the real estate sector, targeting property buyers, renters, and real estate agencies in the Czech Republic. Its business model revolves around listing properties, offering free advertising slots for agencies, and providing value-added services such as legal and mortgage assistance. The platform leverages partnerships with legal and construction firms to enhance service offerings. The presence of job postings indicates organizational growth and stability. The website's content and structure reflect a medium-sized enterprise with consistent branding and a clear focus on the Czech market, supported by international property listings. The company maintains a professional online presence with trust signals such as SSL, privacy policies, and contact transparency.

Security posture

The website enforces HTTPS and integrates Google reCAPTCHA v3 to mitigate automated abuse. Cookie consent is implemented via a reputable third-party service, enhancing privacy compliance. However, the absence of DNSSEC and some recommended security headers (CSP, X-Frame-Options) suggests room for improvement in defense-in-depth. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency in security governance. Overall, the security posture is good but could be enhanced by adopting additional security headers, DNSSEC, and formalizing incident response procedures.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated security policy page and provide incident response contact information to improve transparency and trust.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance with standards and user experience for all users.

Technical notes

Notes

The website is built using Next.js and React, indicating a modern and scalable front-end architecture. Hosting appears to leverage Cloudflare for DNS and CDN services, improving performance and security. Google Tag Manager and reCAPTCHA v3 are integrated for analytics and bot protection. The site uses external CSS from Adobe Typekit and cookie consent scripts from CookieYes. Performance is moderate with good mobile optimization. SEO is supported by proper meta tags and structured data embedded in JSON. Accessibility is basic but could be improved. The technical stack is well chosen for a real estate platform, balancing user experience and security.
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.
