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

eUbytko.cz is an established online accommodation booking platform focused on the Czech Republic market. It offers a wide range of lodging options including apartments, pensions, hotels, cottages, and wellness resorts, targeting tourists and travelers seeking vacation stays within the country. The website features rich content, including categorized accommodation listings, travel guides, and blog articles, enhancing user engagement and decision-making. Technically, the site employs modern JavaScript libraries such as jQuery, Owl Carousel, and Google Tag Manager, with asynchronous script loading to optimize performance. SEO is supported through structured data (JSON-LD) and Open Graph metadata, improving search engine visibility. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though explicit privacy and terms of service pages are not clearly found. The WHOIS data is privacy protected, which is common and justified for this business type. Overall, the site demonstrates a mature digital presence with good usability and trust indicators.

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

6 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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

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, serving as a marketplace connecting accommodation providers with travelers. Its business model revolves around listing properties and facilitating bookings, likely generating revenue through commissions or listing fees. The site targets a broad audience including families, couples, and groups interested in various vacation types such as wellness, active holidays, and nature stays. The presence of social media channels and a mobile app indicates efforts to expand reach and improve customer experience. The company appears to be a medium-sized entity with a strong regional focus in the Czech Republic. No parent or subsidiary companies were identified. The content quality and branding are consistent, supporting a trustworthy market position.

Security posture

The website enforces HTTPS and uses security best practices such as asynchronous script loading and cookie consent management. However, explicit security headers like Content-Security-Policy or X-Frame-Options were not confirmed in the provided data, suggesting room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a security.txt file or vulnerability disclosure policy indicates limited formal incident response readiness. Privacy compliance is partial, with cookie consent present but no clear privacy policy page found. Overall, the security posture is good but could be enhanced by publishing comprehensive policies and implementing additional HTTP security headers.

Recommendations

  1. Publish a clear and comprehensive privacy policy page accessible from the homepage.
  2. Add terms of service and cookie policy pages with explicit user consent mechanisms.
  3. Implement and disclose HTTP security headers such as Content-Security-Policy and X-Frame-Options.
  4. Create and publish a security.txt file to facilitate vulnerability reporting and incident response.
  5. Regularly audit third-party libraries and scripts for vulnerabilities and update them promptly.

Technical notes

Notes

The website uses a modern front-end stack with jQuery and various plugins for UI components like carousels, date pickers, and tooltips. Google Tag Manager and Google Analytics are integrated for tracking and analytics. The site loads resources asynchronously to improve performance and includes responsive design elements for mobile optimization. Structured data in JSON-LD format enhances SEO. However, no specific CMS or hosting provider was identified from the data. Performance is moderate with good mobile optimization but basic accessibility features. The site could benefit from enhanced accessibility compliance and performance tuning to improve user experience further.
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.
