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

Letiště Praha, a.s. operates the Václav Havel Airport Prague, the primary international airport serving the Czech capital. The company provides comprehensive airport services including passenger flights, cargo handling, parking, VIP lounges, and transportation facilitation. It holds a leading market position in Central Europe with a large operational scale and a strong brand presence. The website is professionally designed, mobile-optimized, and rich in content, targeting travelers, airlines, and local businesses. Technically, the website is built on Drupal 10 and integrates multiple modern analytics and marketing tools such as Google Analytics, Microsoft Clarity, Adform, and Bloomreach Exponea. The site demonstrates good performance and accessibility standards, with comprehensive privacy and cookie policies supported by a consent management platform. External service integrations for booking and transportation are clearly linked. From a security perspective, the site enforces HTTPS and maintains privacy compliance with GDPR. However, the absence of WHOIS data and security.txt files slightly reduces trustworthiness. No critical vulnerabilities or exposed sensitive data were detected. The site could improve by implementing security headers and publishing a vulnerability disclosure policy. Overall, Letiště Praha's digital presence is robust and professional, supporting its business operations effectively. Strategic improvements in security transparency and WHOIS data availability would enhance trust and compliance further.

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

5 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube, Cloudflare

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

  3. 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 · found on this site
  • 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

Letiště Praha is positioned as a major transportation hub in Central Europe, serving millions of passengers annually. Its business model revolves around airport operations, including passenger and cargo services, commercial retail, parking, and VIP amenities. The company leverages partnerships with local businesses and service providers to enhance customer experience. The website reflects a mature digital strategy with integrated marketing and analytics tools, supporting customer engagement and operational efficiency. Growth indicators include new flight routes and service expansions. The company maintains a strong partnership ecosystem and demonstrates commitment to sustainability and customer service excellence.

Security posture

The website exhibits a mature security posture with HTTPS enforcement and privacy compliance. The presence of privacy and cookie policies with consent mechanisms indicates GDPR awareness. No exposed credentials or sensitive data were found in the HTML content. However, the lack of visible security headers and absence of a published security.txt file or vulnerability disclosure policy are gaps. Incident response contact information is limited and could be more explicit. Overall, the security maturity is good but can be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a security.txt file to provide clear vulnerability disclosure guidelines and contact information for security researchers.
  3. Enhance visibility and accessibility of incident response and abuse contact channels on the website.
  4. Work with the domain registrar to ensure WHOIS data is complete and publicly available to improve domain trustworthiness.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance with evolving regulations.

The website is built on Drupal 10, a modern and widely supported CMS, indicating a current technology stack. It uses popular JavaScript libraries and frameworks such as Select2 for UI enhancements and LazySizes for image loading optimization. Analytics and marketing integrations include Google Analytics, Microsoft Clarity, Adform, and Bloomreach Exponea, reflecting a sophisticated approach to user behavior tracking and marketing automation.

Performance is moderate, with potential for improvement through optimization of third-party scripts and caching strategies. No critical technical debt or outdated technologies were detected.
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.
