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

HotelyPenziony.cz is a Czech Republic-based online platform specializing in providing a comprehensive directory and booking service for various types of accommodations including hotels, pensions, cottages, and campsites. Operated by ČESKÝ INTERNET s.r.o., the website targets tourists and travelers seeking reliable and affordable lodging options across the Czech Republic. The platform offers price comparison, reservation capabilities, and regional tourist information, positioning itself as a trusted regional hospitality resource since 2010. Technically, the website employs a modern technology stack including Google Analytics, Microsoft Clarity, Smartlook, and Google Tag Manager for analytics and user behavior tracking. It uses asynchronous script loading and consent management tools to comply with privacy regulations. The site is mobile-optimized with good SEO practices and a user-friendly interface, although no specific CMS or hosting provider details were identified. From a security perspective, the site enforces HTTPS and uses consent management for cookies, but lacks explicit security headers and documented security policies or incident response procedures. No vulnerabilities or exposed sensitive data were detected. The WHOIS data is unavailable, likely due to privacy protection, which is common and does not significantly detract from the site's legitimacy given the professional presentation and business information. Overall, HotelyPenziony.cz demonstrates a solid business presence with good technical implementation and privacy compliance. Strategic improvements could include enhancing security headers, publishing a security policy, and increasing transparency around incident response to further strengthen trust and security posture.

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

11 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

    • 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

Business profile

HotelyPenziony.cz operates as a regional hospitality directory and booking platform in the Czech Republic, leveraging its parent company ČESKÝ INTERNET s.r.o. The business model centers on providing a searchable database of accommodations with price comparison and reservation features, monetized likely through advertising and listing fees. The site maintains partnerships with related Czech internet services and integrates social media for brand engagement. Its target customers are domestic and international tourists seeking diverse lodging options. The platform's longevity since 2010 indicates market stability and brand recognition. The presence of multiple analytics and marketing tools suggests active user engagement tracking and optimization efforts. However, the lack of visible certifications or advanced security disclosures may limit appeal to more security-conscious clients.

Security posture

The website maintains a moderate to good security posture with enforced HTTPS and use of consent management tools aligning with GDPR requirements. The absence of key security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No direct evidence of vulnerabilities or exposed sensitive data was found. The site lacks a published security policy or incident response contact, which could hinder rapid response to security incidents. The use of multiple third-party analytics and advertising scripts introduces potential risk vectors that require ongoing monitoring. Overall, the security maturity is adequate for the business type but could be enhanced by adopting best practices in HTTP security headers and transparency around security governance.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts to minimize vulnerabilities from external dependencies.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider obtaining and displaying relevant security or privacy certifications to boost user trust.

Technical notes

Notes

The website uses a combination of modern JavaScript libraries and analytics tools such as Google Analytics, Microsoft Clarity, Smartlook, and Google Tag Manager, indicating a mature approach to user behavior analysis and marketing. The presence of asynchronous script loading and consent management reflects attention to performance and privacy compliance. The site is mobile-optimized with responsive design elements and uses popular UI components like Chosen for select inputs and Slick Carousel for banners. However, no specific CMS or hosting provider was identified, which may indicate a custom or proprietary platform. Performance is moderate, with potential for improvement in loading speed and accessibility compliance. The technical stack is well-suited for the business model but could benefit from enhanced security configurations and modernization of legacy scripts.
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.
