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

The website www.luxusni-lyzovani.cz operates as an online travel agency specializing in luxury ski vacations primarily in the European Alps, targeting Czech-speaking customers. It offers hotel bookings and ski packages in Austria, Italy, France, and other destinations, supported by clear contact information and customer support via phone. The business appears to be a small-sized entity named Delta Reisen, with a professional and consistent brand presentation. Technically, the site uses modern JavaScript libraries such as jQuery and OpenLayers, integrates Google Tag Manager and Facebook Pixel for analytics and marketing, and is built on the CeSYS travel agency platform. The website is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security-wise, the site enforces HTTPS and uses cookie consent mechanisms but lacks explicit security headers and published privacy or terms of service policies. The absence of WHOIS data reduces domain trustworthiness, though no malicious or suspicious content is detected. Overall, the site is functional and professional but would benefit from enhanced privacy compliance and security transparency.

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.

Priority findings

8 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

      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

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 company positions itself in the niche luxury ski travel market within the Czech Republic, focusing on premium ski destinations in the Alps. Its competitive advantage lies in specialized offerings, detailed destination data, and bundled services including Covid insurance. The business model is commission-based online travel bookings. The target customers are affluent Czech travelers seeking high-end ski vacations. The presence of multiple destination filters and detailed hotel parameters indicates a mature booking platform. Growth potential exists through expanded marketing and enhanced digital presence. Partnerships with hotels and ski resorts are implied but not explicitly listed. The company maintains a moderate level of trust signals but lacks public certifications or compliance documentation.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and cookie consent implemented, indicating awareness of privacy regulations. However, the absence of a published privacy policy, terms of service, and incident response information are notable gaps. Security headers such as Content-Security-Policy and X-Frame-Options are not detected, which could expose the site to certain web-based attacks. No vulnerable or outdated libraries are evident, and no sensitive data is exposed in the HTML. The use of third-party analytics and tracking pixels is transparent but should be accompanied by clear user consent and data retention policies. Overall, the security maturity is adequate for a small travel agency but requires improvements to meet higher compliance standards.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve transparency and compliance.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear incident response and vulnerability disclosure information to enhance trust.
  4. Improve accessibility features to broaden user inclusivity and meet standards.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize user tracking.

Technical notes

Notes

The website is built on the CeSYS travel agency platform and leverages popular JavaScript libraries including jQuery and OpenLayers for mapping. It uses Slick Slider for content carousels and integrates Google Tag Manager and Facebook Pixel for analytics and marketing. The site is served over HTTPS with a moderate performance profile and good mobile responsiveness. SEO is supported by proper meta tags and structured navigation. However, there is no explicit CMS identified beyond CeSYS, and hosting provider details are not disclosed. The site could benefit from enhanced accessibility and performance optimizations. No critical technical debt or risks were identified, but security header implementation is recommended.
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.
