The platform emphasizes direct contact between renters and property owners, eliminating commission fees and intermediaries. It offers a comprehensive catalog of properties across various regions and thematic categories, targeting families, groups, and individuals seeking vacation rentals.

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. 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

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 operates in the hospitality sector, focusing on direct rentals of holiday homes without intermediaries, which is a competitive advantage in reducing costs for renters and owners. Its market position is niche but well-established within Czech and Slovak vacation rental markets. The business model relies on property owner registrations and user searches for accommodations, supported by partner sites in related accommodation and real estate sectors. The website's extensive catalog and thematic filters cater to diverse customer needs, including seasonal and activity-based rentals. Growth potential lies in expanding property listings and enhancing digital marketing. The partnership ecosystem includes well-known Czech rental and real estate platforms, enhancing credibility and reach. However, the lack of visible direct contact information and incomplete WHOIS data may impact user trust and regulatory compliance.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and use of reputable analytics and tracking services. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options is a gap that could expose the site to certain web-based attacks. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism, which is a compliance risk under GDPR. Incident response and security policy information are not publicly available, indicating limited transparency in security governance. Overall, the security posture is adequate for a hospitality listing site but requires enhancements to meet higher compliance and security standards.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Deploy a cookie consent banner/mechanism to comply with GDPR and improve user privacy transparency.
  3. Publish a clear security policy and incident response contact information to improve trust and readiness.
  4. Enhance WHOIS domain registration information to improve domain legitimacy and trustworthiness.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website uses a traditional web stack with jQuery 1.9.1 and lazy loading for images, FontAwesome for icons, and integrates Google Tag Manager and Facebook Pixel for analytics and marketing. The site is hosted behind Cloudflare, providing CDN and security benefits. Performance is moderate with asynchronous loading of scripts. The site is not explicitly mobile-optimized but has basic responsiveness. SEO is supported by proper meta tags, Open Graph tags, and JSON-LD structured data for search actions. Accessibility features are basic, with room for improvement in ARIA roles and semantic HTML. The absence of a modern CMS or framework is noted, which may limit scalability and maintainability. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced accessibility.
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.
