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

TUI Poland Sp. z o.o. operates the website www.tui.cz as a leading travel agency offering a wide range of all inclusive and last minute vacation packages, tours, and charter flights to popular destinations worldwide. The company positions itself as the number one travel agency in Europe, targeting general consumers seeking organized travel experiences. The website is professionally designed with good content quality and consistent branding, supported by official social media channels and a clear customer service contact number. Technically, the website leverages modern web technologies including React and Next.js frameworks, with integrations for Cookiebot for cookie consent management, Google Analytics, and Hotjar for analytics and user behavior tracking. The site demonstrates good mobile optimization and SEO practices, although accessibility features could be improved. Performance is moderate, with a comprehensive set of meta tags and structured data enhancing search engine visibility. From a security perspective, the website enforces HTTPS with strong SSL configuration and includes standard security headers. Cookie consent mechanisms are implemented in compliance with GDPR, and privacy policies are comprehensive and accessible. However, the absence of WHOIS data and lack of explicit security policy or incident response information represent gaps in transparency and trustworthiness. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website presents a low-risk profile with strong business credibility and privacy compliance. Strategic recommendations include publishing a dedicated security policy, incident response contacts, and vulnerability disclosure information to enhance trust and compliance. Improving accessibility and adding a terms of service page would further strengthen the user experience and legal 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

3 findings rated critical or high. Fix these first.

  1. 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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

TUI Poland Sp. z o.o. operates in the hospitality sector as a major European travel agency. Its business model focuses on packaged travel services including all inclusive vacations, last minute deals, and charter flights. The company targets a broad consumer base interested in convenient and organized travel. Market positioning as Europe's number one travel agency suggests strong competitive advantages and brand recognition. The website's integration with multiple marketing and analytics platforms indicates a mature digital marketing strategy. The absence of WHOIS data is a notable anomaly but does not detract from the company's apparent market presence. The company maintains active social media engagement, supporting customer outreach and brand loyalty.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, robust SSL configuration, and implementation of key security headers such as Content-Security-Policy and Strict-Transport-Security. Cookie consent is managed via Cookiebot, ensuring GDPR compliance. No exposed sensitive data or vulnerable libraries were identified in the HTML content. However, the lack of a published security policy, incident response contacts, or vulnerability disclosure program limits transparency and preparedness perception. The WHOIS data absence raises concerns about domain registration transparency. Overall, the security posture is strong but could benefit from enhanced policy disclosures and incident readiness communication.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Establish and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance website accessibility features to improve compliance and user experience.
  5. Add a comprehensive terms of service page to clarify user rights and obligations.

Technical notes

Notes

The website is built on a modern technology stack using React and Next.js frameworks, enabling server-side rendering and improved SEO. It employs Cookiebot for cookie consent management and integrates Google Analytics and Hotjar for detailed user behavior analytics. The site uses web fonts and optimized images for performance. While the hosting provider is not explicitly identified, the presence of AWS-related cookies suggests cloud infrastructure usage. Performance is moderate with good mobile optimization and SEO meta tags. Accessibility is basic and could be improved. No CMS is explicitly detected, indicating a custom or framework-based solution. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
