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

Letenky.cz is a Czech-based online travel affiliate platform specializing in offering cheap flight tickets, hotel bookings, car rentals, and travel insurance. The website targets budget-conscious travelers primarily in the Czech Republic, providing access to discounted and last-minute travel deals from over 800 companies. The business model relies on affiliate partnerships and travel deal aggregations, positioning itself as a niche player in the local travel market. Technically, the site is built on WordPress with Bootstrap and jQuery, integrating third-party affiliate widgets such as Pelikan flights. The site demonstrates good mobile optimization and a professional design, though accessibility features are basic. Security posture is moderate with HTTPS enabled and cookie consent implemented, but lacks important security headers and explicit privacy or security policies. No contact information or terms of service pages were found, which may impact user trust and compliance. Overall, the domain registration data aligns well with the website content, indicating a legitimate small business startup in the travel sector.

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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL 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

  4. 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 Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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

The platform operates as an affiliate marketing site in the transportation and hospitality sectors, focusing on flight and vacation package deals. Its competitive advantage lies in aggregating offers from a large number of airlines and travel providers, targeting Czech-speaking customers seeking affordable travel options. The business model is commission-based through affiliate links. The website links to multiple partner domains, indicating a broad partnership ecosystem. Growth potential depends on expanding affiliate relationships and improving user trust through enhanced transparency and compliance. The absence of direct contact details and formal policies may limit credibility with more cautious customers.

Security posture

The website employs HTTPS, ensuring encrypted communication, and implements a cookie consent banner supporting GDPR compliance. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and HSTS, which are important for mitigating common web attacks. No explicit security or incident response policies are published, and no dedicated security contact channels are provided. The absence of these elements suggests a basic security maturity level appropriate for a small affiliate site but with room for improvement to reduce risk exposure and enhance user trust. No vulnerabilities or malware indicators were detected in the provided content.

Recommendations

  1. Implement essential security headers including Content-Security-Policy, X-Frame-Options, and HSTS to strengthen web security.
  2. Publish a clear privacy policy and terms of service to improve legal compliance and user trust.
  3. Add visible and verified contact information including support emails and phone numbers to enhance credibility.
  4. Establish and communicate an incident response process with dedicated security contact channels.
  5. Conduct regular security audits and update all software components to mitigate vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress CMS with Bootstrap for responsive design and jQuery for interactivity. It integrates third-party affiliate widgets for flight deals, enhancing functionality. Performance is moderate with no major issues detected, though no advanced analytics or tracking services were found. SEO is supported by proper meta tags and structured navigation. Accessibility is basic and could be improved. The hosting provider is not explicitly identified from the content. Overall, the technical infrastructure is adequate for a small affiliate travel site but could benefit from enhanced security and accessibility features.
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.
