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

Reality Klatovy is a specialized regional real estate listing platform focused on the Klatovy district in the Czech Republic. Operated by ČESKÝ INTERNET s.r.o., the website aggregates property listings for sale and rent, including offerings from verified real estate agencies and private sellers. It provides users with advanced search filters, broker catalogs, and relevant real estate articles, positioning itself as a trusted local resource for property seekers. The business model centers on providing a comprehensive online marketplace for real estate transactions in the region, leveraging partnerships with larger real estate networks to enhance its offerings. Technically, the site employs modern web technologies including Vue.js, jQuery, and integrates Google Analytics and Tag Manager for tracking and marketing purposes. The presence of a cookie consent mechanism and privacy policy indicates attention to privacy compliance. Security posture is solid with HTTPS enforced and basic security headers present, though there is room for improvement by adding advanced headers and publishing security policies. The absence of WHOIS data due to privacy protection is common for small businesses and does not detract from the site's legitimacy given the professional content and clear business information. Overall, the website demonstrates a mature digital presence suitable for its market niche, with good user experience and trust indicators.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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';…

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 individuals and businesses interested in buying, selling, or renting properties in the Klatovy district. Its competitive advantage lies in its regional focus combined with integration into larger real estate networks, offering a broad inventory of listings. Revenue likely derives from advertising, featured listings, and partnerships with real estate agencies. The platform supports growth through content such as articles and broker catalogs, enhancing user engagement. Partnerships with entities like realitniservery.cz and the parent company ČESKÝ INTERNET s.r.o. provide operational and technological support. The business maintains a small size but shows consistent branding and content quality, indicating stable market presence.

Security posture

The website enforces HTTPS, uses cookie consent management, and includes a privacy policy, reflecting a baseline compliance with GDPR and security best practices. However, it lacks advanced security headers such as Content-Security-Policy and does not publish incident response or vulnerability disclosure policies. No visible vulnerabilities or exposed sensitive data were detected. The security score is moderate, with recommendations to enhance header implementation and publish security documentation to improve transparency and resilience. The absence of a security.txt file and incident response contacts suggests limited formal security governance, typical for small businesses but an area for improvement.

Recommendations

  1. Implement additional HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen browser security.
  2. Publish a security.txt file and incident response policy to provide clear channels for vulnerability reporting and improve trust.
  3. Enhance accessibility features to improve compliance and user experience for all users.
  4. Consider adding explicit terms of service and data protection officer contact information to improve compliance transparency.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure GDPR compliance.

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.
