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

Chalupyachaty.cz is a Czech Republic based online platform specializing in verified holiday rentals of cottages, chalets, and similar recreational properties. The website offers direct contact to property owners, ensuring updated availability and verified reviews, targeting families and groups seeking trustworthy vacation accommodations. Technically, the site uses a traditional web stack with jQuery, jQuery UI, Google Tag Manager for analytics, and MapLibre GL for map visualization, hosted behind Cloudflare DNS. Security posture is moderate with HTTPS enabled but lacks advanced security headers and uses outdated JavaScript libraries. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the domain is well-established since 2003, supporting business legitimacy. Strategic improvements in privacy compliance and security hardening are recommended.

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

10 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. 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"

    • 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 platform occupies a niche in the Czech hospitality market by focusing on verified direct rentals of cottages and chalets, differentiating itself through manual selection and owner direct contact. Its business model avoids intermediaries, likely reducing costs for renters and owners. The partnership with related sites like e-chalupy.cz and e-penziony.cz expands its market reach. The target audience includes domestic tourists seeking reliable and authentic lodging options. The website's longevity since 2003 indicates stable operations, though the small size suggests a focused rather than expansive market presence.

Security posture

The website demonstrates a basic security posture with HTTPS enforced and Cloudflare DNS usage. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are important to mitigate common web attacks. The use of an outdated jQuery version (1.12.4) may expose the site to known vulnerabilities. No explicit incident response or vulnerability disclosure policies are present, and no security contact emails are found. Privacy compliance is insufficient, with no visible privacy or cookie policies, which may expose the business to regulatory risks under GDPR. Overall, security maturity is moderate but requires enhancements to meet best practices.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Upgrade JavaScript libraries, especially jQuery, to the latest secure versions to mitigate vulnerabilities.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Establish and publish a vulnerability disclosure policy and security contact information to improve incident response readiness.
  5. Enhance mobile optimization and accessibility features to improve user experience and SEO.

Technical notes

Notes

The website uses a classic web technology stack including jQuery 1.12.4, jQuery UI 1.11.4, Google Tag Manager for analytics, and MapLibre GL JS for interactive maps. Hosting is behind Cloudflare DNS, which provides DNS security and performance benefits. The site has valid meta tags and SEO-friendly content in Czech language. Performance is moderate with room for improvement, especially in mobile responsiveness and accessibility. The site lacks modern frontend frameworks or CMS indications, suggesting a custom or legacy build. Technical debt is indicated by outdated libraries and missing security headers. Opportunities exist to modernize the stack, improve security, and enhance user experience.
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.
