Centrum vzorových domů (cvzd.cz) is a Czech Republic based company specializing in the exhibition and sale of modern and classic family houses. Established in 2015 and operated by CANABA a.s., it positions itself as the largest permanent year-round exhibition of family houses in the country, targeting individuals and families planning to build or buy homes. The website offers detailed information about various model houses, free project documentation, and consultation services, supported by a professional and user-friendly digital presence. Technically, the site employs modern frameworks such as Bootstrap and jQuery, integrates Google Tag Manager and reCAPTCHA for security and analytics, and uses a cookie consent management platform to comply with privacy regulations. Security posture is solid with HTTPS and form protections, though some security headers could be enhanced. Overall, the site demonstrates a mature digital infrastructure aligned with business goals and regulatory compliance.

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

5 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

  2. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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, focusing on showcasing and facilitating the construction of family houses. Its business model revolves around providing customers with tangible house models, free project plans, and direct construction services, creating a comprehensive customer journey from inspiration to realization. The market position is strong within the Czech Republic, leveraging partnerships with design and web agencies to maintain a professional brand image. Revenue streams likely include house sales, project documentation fees, and construction contracts. The target customers are prospective homeowners seeking modern, energy-efficient housing solutions. The partnership ecosystem includes design and marketing firms, enhancing the company's market reach and service quality.

Security posture

The website exhibits a good security maturity level with enforced HTTPS, integration of Google reCAPTCHA v3 to protect forms from spam and abuse, and a comprehensive cookie consent mechanism ensuring GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. There is no visible incident response or security policy information, which could be beneficial for transparency and preparedness. Overall, the security posture is adequate for the business type but could be enhanced with additional headers and a published security policy.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a security policy and incident response contact information to improve transparency and readiness.
  3. Regularly update all third-party libraries and scripts to their latest secure versions.
  4. Enhance accessibility features to meet WCAG standards for broader user inclusivity.
  5. Consider adding a security.txt file to facilitate responsible vulnerability disclosures.

Technical notes

Notes

The website is built on a modern technology stack including Bootstrap 5.3.3 for responsive design, jQuery and jQuery UI for interactive elements, and Google Tag Manager for analytics and marketing integrations. Hosting and domain registration are managed by Active24, a reputable provider. Performance is moderate with asynchronous loading of scripts and optimized images. The site is mobile-optimized with responsive layouts and accessible navigation. SEO is supported by appropriate meta tags and structured content. Technical debt appears low, but the absence of a known CMS suggests a custom or bespoke solution which may require dedicated maintenance resources. Overall, the technical infrastructure supports the business needs effectively with opportunities for incremental improvements.
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.
