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

The website www.reality-jindrichuv-hradec.cz operates as a regional real estate listing platform focused on the Jindřichův Hradec district in the Czech Republic. It aggregates property listings for sale and rent, including offerings from verified real estate agencies and private sellers. The platform also provides catalogs of brokers and agencies, along with relevant real estate articles, targeting individuals and businesses interested in local real estate transactions. The parent company, Český Internet s.r.o., is a Czech internet service provider and digital solutions company, lending credibility and operational support to the site. Technically, the website employs modern web technologies such as Vue.js and jQuery, integrates Google Analytics and Google Tag Manager for analytics, and uses a consent management platform to comply with privacy regulations. The site is served over HTTPS, ensuring encrypted communications. The design is professional, mobile-optimized, and offers a good user experience with clear navigation and relevant content. However, some security best practices such as implementing security headers and publishing security policies are missing. From a security perspective, the site shows a moderate security posture with HTTPS enabled and no exposed sensitive data. The presence of cookie consent mechanisms and a privacy policy indicates GDPR compliance efforts. The lack of WHOIS data due to privacy protection is common and justified for this business type. No critical vulnerabilities or suspicious patterns were detected. Overall, the site is trustworthy and professionally maintained but could improve security headers and incident response transparency. The overall risk assessment is low, with recommendations to enhance security headers, add a security.txt file, and provide clearer contact channels such as phone numbers and terms of service. These improvements would strengthen user trust and compliance posture while maintaining the site's role as a key regional real estate marketplace.

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';…

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 operates in the real estate sector, focusing on a regional market niche in the Jindřichův Hradec district. Its competitive advantage lies in aggregating verified listings from multiple real estate agencies and private sellers, providing a comprehensive property search experience. The business model is primarily advertising and lead generation for real estate agents and agencies, supplemented by content marketing through articles. The target customers are local buyers, sellers, renters, and real estate professionals. Growth indicators include a sizable catalog of brokers and agencies and frequent new listings. The partnership ecosystem includes Český Internet s.r.o. as the parent company and realitniservery.cz as a key partner network. Strategic observations suggest focusing on expanding digital marketing, improving security and compliance transparency, and enhancing user engagement features to strengthen market position.

Security posture

The website demonstrates a moderate security maturity level with HTTPS encryption and cookie consent mechanisms in place. No critical vulnerabilities or exposed sensitive data were found in the HTML content. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security indicates room for improvement. There is no visible security policy or incident response information, which limits transparency and preparedness. GDPR compliance is supported by the privacy policy and consent management but could be enhanced with clearer data retention disclosures. The use of third-party scripts and analytics is managed with consent, reducing privacy risks. Overall, the security posture is adequate for a small to medium business but should be improved to meet higher standards and user expectations.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to mitigate common web attacks.
  2. Publish a security.txt file and a clear incident response policy page to improve transparency and facilitate vulnerability reporting.
  3. Add visible and verified company phone numbers to enhance contact options and trustworthiness.
  4. Develop and publish terms of service and detailed privacy notices including data retention policies to strengthen compliance.
  5. Regularly audit and update third-party scripts and dependencies to minimize security risks and maintain performance.

Technical notes

Notes

The website uses a combination of Vue.js and jQuery for frontend interactivity, supported by multiple plugins for UI components such as multiple select dropdowns, lazy loading images, and date pickers. Analytics are implemented via Google Analytics and Google Tag Manager, with additional tracking pixels from Facebook and Twitter. The site is served over HTTPS with a valid SSL certificate, ensuring secure data transmission. The design is responsive and mobile-friendly, with good SEO practices including meta tags and Open Graph data. However, the absence of a detected CMS suggests a custom or proprietary platform. Performance is moderate, with some optimization opportunities in script loading and caching. Accessibility is basic but could be improved with ARIA attributes and keyboard navigation support. Overall, the technical infrastructure is solid but could benefit from modernization and enhanced security configurations.
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.
