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

HyperReality.cz is a well-established Czech real estate portal operated by BigZoom, a.s., offering a wide range of property listings including apartments, houses, commercial properties, land, and holiday homes. The platform targets individuals and businesses interested in buying or renting real estate primarily in the Czech Republic, with some listings abroad. The website features extensive listings and integrates various tools such as price maps and directories of real estate agencies, positioning itself as a key player in the Czech real estate market. Technically, the website employs a modern technology stack with integrations including Google Analytics, Google Tag Manager, Hotjar, Gemius, and multiple advertising and retargeting services. It uses HTTPS with good SSL configuration and includes a consent management platform for cookie compliance. However, it lacks some security headers and explicit privacy and terms of service pages, which are important for compliance and user trust. From a security perspective, the site shows a mature posture with encrypted connections and no visible vulnerabilities or exposed sensitive data. The use of multiple third-party scripts necessitates ongoing security audits to mitigate risks. The absence of WHOIS data due to privacy protection is common and does not detract significantly from the site's legitimacy, given the professional presentation and trust signals. Overall, HyperReality.cz is a credible and professional real estate portal with good technical and security foundations but would benefit from enhanced transparency in privacy policies and security practices to improve compliance and user trust.

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.

Priority findings

8 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

  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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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

HyperReality.cz operates in the competitive Czech real estate market, leveraging a comprehensive online platform to aggregate and present property listings. Its business model centers on advertising and lead generation for real estate agencies and private sellers. The site’s extensive use of analytics and advertising technologies indicates a data-driven approach to user engagement and monetization. The presence of partner directories suggests a strong ecosystem of real estate professionals. The company’s large size and established brand presence provide competitive advantages, though the lack of visible direct contact information may limit some user trust. Growth opportunities include expanding international listings and enhancing user experience through improved transparency and security compliance.

Security posture

The website demonstrates a solid security posture with enforced HTTPS and no visible exposure of sensitive data. The integration of a consent management platform aligns with GDPR requirements, although the absence of a published privacy policy and terms of service is a compliance gap. The lack of security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. The extensive use of third-party scripts increases the attack surface, necessitating regular security reviews. No incident response or security contact information is provided, which could hinder timely vulnerability reporting and mitigation. Overall, the site is secure but could improve compliance and resilience by addressing these gaps.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages prominently linked on the website.
  2. Implement and configure essential security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information for security incidents and designate a Data Protection Officer if applicable.
  4. Regularly audit and update third-party scripts to minimize vulnerabilities and ensure compliance with privacy regulations.
  5. Enhance accessibility features and conduct periodic security training to foster a strong security culture.

Technical notes

Notes

The website uses a modern and diverse technology stack including Google Analytics, Tag Manager, Hotjar, Gemius, and multiple advertising platforms, indicating a mature digital marketing infrastructure. It integrates mapping APIs from Google and Mapy.cz to enhance user experience. The site is mobile optimized and uses web fonts for consistent branding. Performance is moderate, with potential improvements in loading times due to multiple third-party scripts. No CMS is explicitly detected, suggesting a custom or proprietary platform. The absence of security headers and explicit privacy documentation are technical debt areas. Overall, the infrastructure supports business goals but requires enhancements in security and compliance to reduce risks.
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.
