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

Holiday.cz is a Czech Republic-based online travel and holiday booking platform operated by Agentura Paseo. The website offers a variety of services including holiday packages, last minute deals, flight tickets, and accommodation bookings. It targets a general audience interested in travel and leisure within the Czech market. The platform integrates multiple advertising networks and analytics tools, leveraging WordPress CMS with SEO optimizations to maintain a competitive online presence. Technically, the site demonstrates moderate performance and good mobile optimization, with a solid but improvable security posture. The absence of publicly available WHOIS data suggests privacy protection, which is common but reduces transparency. Privacy and cookie policies are not clearly found, indicating an area for compliance improvement.

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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

      Missing Strict-Transport-Security header

      Forces HTTPS connections

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

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 business operates in the hospitality sector, focusing on travel and holiday services. It maintains partnerships with several related Czech portals, enhancing its market reach. The business model revolves around aggregating travel offers and facilitating online bookings, likely generating revenue through advertising and affiliate commissions. The website's content and structure indicate a medium-sized enterprise with a consistent brand presence. However, the lack of explicit contact information and privacy policies may affect user trust and regulatory compliance. The company appears to have a stable market position within the Czech travel industry, supported by a network of related sites under the Agentura Paseo umbrella.

Security posture

The website employs HTTPS and integrates security-related scripts such as Google reCAPTCHA, indicating a baseline security awareness. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not confirmed in the provided content and should be verified or implemented. No sensitive data exposure or vulnerable libraries were detected in the HTML. The absence of clear incident response contacts and security policies suggests limited transparency in security governance. Overall, the security posture is moderate but could be enhanced by formalizing security policies, improving header configurations, and providing clear user privacy and security information.

Recommendations

  1. Implement and publicly display comprehensive privacy and cookie policies with user consent mechanisms to ensure GDPR compliance.
  2. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Provide clear contact information including emails and phone numbers for customer support and incident response.
  4. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
  5. Enhance transparency by publishing WHOIS or registrant information where possible or explaining privacy protection rationale.

Technical notes

Notes

The website is built on WordPress CMS, utilizing Yoast SEO Premium for search optimization and Google Tag Manager for analytics and marketing integration. Advertising is managed through Google Adsense and Seznam Ads networks. The site uses modern web fonts and JavaScript libraries like jQuery and Flatpickr for enhanced user experience. Performance is moderate with good mobile responsiveness and basic accessibility features. The technical infrastructure is typical for a medium-sized online travel portal but could benefit from performance tuning and accessibility improvements. Hosting provider details are not explicitly found in the content. Overall, the technical setup supports the business needs but leaves room for modernization and security hardening.
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.
